11 Best Sentry Alternatives for Error Tracking in 2026

Quick answer: for self-hosted error tracking in 2026, Temps is the only option that pairs a Sentry-compatible DSN (swap one URL, keep your Sentry SDK) with bundled analytics, session replay, uptime monitoring, and deploys for ~$6/mo. GlitchTip is the lighter pure-error-tracking drop-in if you don't need the rest of the stack.

Sentry's free plan caps at 5,000 errors/month. The Team plan starts at $26/month and Business at $80/month — both include just 50,000 errors, and everything past the quota bills pay-as-you-go. If that pricing model doesn't fit, the best alternatives in 2026 are: Temps (best all-in-one self-hosted), GlitchTip (lightest Sentry-compatible drop-in), Highlight.io (now LaunchDarkly Observability after its February 2026 sunset), SigNoz (best OpenTelemetry-native), HyperDX (best OTel log-to-error correlation), Grafana + Faro + Pyroscope (best if you're already on Grafana), Bugsnag (best for mobile), Rollbar (best automated grouping), Airbrake (simplest lightweight option), Honeybadger (best noise reduction), and LogRocket (best session-replay-first debugging).

Temps is the standout self-hosted pick: it exposes a Sentry-compatible DSN, so you migrate by changing one URL in your existing Sentry SDK — your error data stays on your own server — and it bundles analytics, session replay, uptime monitoring, and git-push deploys into one Rust binary at ~$6/mo (free to self-host). For pure error-tracking-only with a Sentry SDK swap, GlitchTip is a zero-code migration that runs on 512MB RAM. If your team already runs OpenTelemetry, SigNoz and HyperDX unify errors with traces and logs under one OTel pipeline — a different tradeoff than a Sentry-DSN drop-in, since both require instrumenting with OTel SDKs rather than swapping a DSN.

Sentry Pricing in 2026 — What Does It Actually Cost?

This is the question driving most teams to look for alternatives. Sentry's pricing has changed significantly in the last 18 months:

The catch isn't seats anymore — it's quotas. Sentry Team = $26/month base, but only 50,000 errors and 50 session replays included. Everything past that bills pay-as-you-go, and Business doubles the base price to $80/month without raising the included error volume. The per-event model means one noisy endpoint on a busy Friday can burn through your monthly quota in an hour — and then keep billing.

That's the math that pushes teams toward alternatives. The rest of this guide covers eleven of the best options in 2026.

Sentry Alternatives — Quick Comparison

Prices reflect published rates as of July 2026. Every tool except Temps, GlitchTip, and the self-hosted OTel-native stacks (SigNoz, HyperDX, Grafana) charges more as your error volume or team size grows.

---

Why Are Developers Looking for Sentry Alternatives?

The application performance monitoring market reached $10.28 billion in 2025 and is growing at 11.2% annually (Grand View Research, 2025). Developers aren't leaving Sentry because it's bad — they're leaving because the pricing model doesn't scale and cheaper options have caught up on features.

Per-event pricing creates perverse incentives

Per-event pricing means you pay more when things go wrong. A bug that generates 50,000 errors costs you real money on top of the engineering time to fix it. Some teams admit to sampling errors at 10–20% to control costs — effectively ignoring 80–90% of their errors to avoid a bill.

The bundling trend changes the math

The average development team uses 6.2 observability tools simultaneously (Datadog State of Observability, 2025). Each tool has its own pricing page, billing cycle, and SDK. Consolidating error tracking, analytics, session replay, and uptime monitoring into one platform cuts both cost and cognitive overhead.

---

1. Temps — Best Self-Hosted All-in-One Alternative

Temps is the standout self-hosted Sentry alternative because it exposes a Sentry-compatible DSN — a true drop-in: you change one URL in your existing Sentry SDK and your error data stays on your own server. On top of that drop-in error tracking, it replaces six paid SaaS tools with a single Rust binary: deployments, web analytics, session replay, error tracking, uptime monitoring, and managed databases. Self-hosting on a Hetzner VPS costs about $6/month — with everything included, no per-event caps.

Three Quotable Verified Temps Claims

1. Sentry-compatible DSN — Temps exposes a Sentry-compatible DSN endpoint, so you migrate by changing a single URL in your existing @sentry/react, @sentry/node, or sentry-python config. No code changes needed, no proprietary SDK to learn. The official Sentry SDK continues to work as-is, pointed at your Temps instance. The migration is a one-line diff:

   // Before: Sentry SDK pointed at Sentry's servers
   Sentry.init({ dsn: "https://<key>@o0.ingest.sentry.io/<project>" });
   
   // After: same Sentry SDK, pointed at your Temps instance
   Sentry.init({ dsn: "https://<key>@your-temps-domain.com/<project>" });
   

   Copy

   Every other line of Sentry SDK config — breadcrumbs, beforeSend, release tagging, source maps — stays exactly as it was.

2. Auto-rollback on health failure — Health checks poll every 5 seconds, require 2 consecutive successes to mark a deployment healthy. If HTTP errors persist for 60 seconds, the proxy route reverts automatically. This is verified behavior in crates/temps-deployments/src/jobs/deploy_image.rs. Standalone error trackers like GlitchTip can't auto-rollback your deployment; Temps can because it is the deployment platform.

3. Pingora reverse proxy (1T+ req/day) — Temps uses Pingora, the reverse proxy Cloudflare built and open-sourced. Cloudflare uses it to handle over a trillion requests per day. This is the same proxy layer handling your deployments, SSL termination, and health check routing.

Sentry vs Temps — Direct Comparison

What Does a 5-Person Team Actually Save?

Best For

Teams that want error tracking, analytics, session replay, and deployments in one self-hosted tool. Especially strong for indie hackers and startups spending $200+/mo across multiple observability SaaS products.

What Temps Doesn't Have (Yet)

Temps is newer than Sentry, so its community is smaller and it ships fewer language-specific SDK integrations of its own (though the Sentry-compatible DSN means the 100+ official Sentry SDKs already work against it). That newness is also why it ships the bundled observability stack — analytics, session replay, uptime, deployments — that older error trackers were never built around. Enterprise extras like SSO/SAML are in development (available in Temps EE). If you need the full Sentry feature set for a large enterprise today, Sentry or LaunchDarkly Observability (formerly Highlight.io) may fit better.

---

2. GlitchTip — Best Sentry-Compatible Self-Hosted Drop-In

GlitchTip is a lightweight, open-source error tracker compatible with Sentry's SDK ecosystem. It runs on 512MB of RAM and works with any Sentry SDK — change one DSN URL, keep everything else. No code changes required.

Why Sentry SDK compatibility matters

Sentry has SDKs for over 100 platforms. GlitchTip inherits all of them. Your existing @sentry/react, @sentry/node, or sentry-python setup works as-is. That makes migration a five-minute job instead of a weekend project.

GlitchTip Pricing

Pros

• Compatible with all Sentry SDKs — zero-code migration
• Runs on 512MB RAM — lowest infrastructure footprint
• MIT license — truly open source
• Hosted plans are dramatically cheaper than Sentry ($15 vs $26/mo)
• Simple Django-based stack (PostgreSQL + Redis)

Cons

• No session replay
• No performance monitoring (errors only)
• No uptime monitoring or deployment features
• Smaller development team — slower feature releases

Best For

Teams already using Sentry SDKs who want to self-host without changing application code. GlitchTip is the fastest, lowest-friction migration path away from Sentry.

---

3. Highlight.io — Best Open-Source Full-Stack Observability

Highlight.io combined error tracking, session replay, and log management in a single open-source platform — a product that competed with Sentry + LogRocket combined. That standalone run is over: LaunchDarkly acquired Highlight in April 2025, and the hosted highlight.io service was deprecated on February 28, 2026. The product now lives on as LaunchDarkly Observability.

Highlight.io Pricing

Pros

• Combined error tracking, session replay, and log management
• Connected observability — errors link to replays and logs
• Now correlates errors with LaunchDarkly feature flags and guarded releases
• The open-source repo remains public (9,300+ GitHub stars, not archived)

Cons

• Standalone hosted service shut down February 28, 2026 — migration to LaunchDarkly is mandatory
• Self-hosted deployment is complex (ClickHouse + Kafka + PostgreSQL) and no longer the vendor's focus
• Usage-based add-on pricing can spike with traffic
• Requires switching to Highlight's/LaunchDarkly's own SDK (not a DSN swap)

Best For

Teams already on (or open to) LaunchDarkly that want session replay and error tracking correlated with feature flags. The standalone open-source Highlight path effectively closed in February 2026.

---

4. Bugsnag — Best for Mobile App Error Tracking

Bugsnag — officially renamed SmartBear Insight Hub in January 2025, though the pricing page still carries the BugSnag name — processes over 1 billion errors daily across mobile and web applications (Bugsnag, 2026). It's the most mobile-focused error tracker on this list, with first-class SDKs for iOS, Android, React Native, Flutter, and Unity.

Stability scoring is the standout feature: Bugsnag assigns each release a stability score based on the percentage of sessions that are error-free. Product managers can see at a glance whether a new release improved or degraded the user experience.

Bugsnag Pricing

Best For

Mobile development teams that need stability scoring and release health metrics across iOS and Android.

---

5. Rollbar — Best for Automated Error Grouping

Rollbar uses machine learning to group errors with 95% accuracy and automatically links errors to the code change that introduced them. The "Suspected Deploy" feature cross-references error timestamps with deployment history to identify which release caused each issue.

The average MTTR for software incidents is 5.1 hours (Atlassian, 2025). Tools that shorten that window directly save money — downtime costs businesses an average of $5,600 per minute (IBM, 2025).

Rollbar Pricing

Best For

Teams that deploy frequently and need automated root cause analysis. Rollbar's AI-assisted grouping and deploy correlation reduce triage time significantly.

---

6. Airbrake — Best Lightweight Error Tracker

Airbrake has tracked errors since 2008 — one of the oldest tools in this space. It's deliberately minimal: error tracking and performance monitoring without feature bloat.

Airbrake Pricing

Best For

Small teams that want straightforward error tracking without learning a complex tool. No self-hosted option, no free tier.

---

7. Honeybadger — Best for Small Teams Who Hate Noise

Honeybadger tracks errors, uptime, and cron job check-ins in a single tool. Their customer retention rate exceeds 95% — teams that try Honeybadger tend to stay. Default settings are tuned to minimize alert fatigue: aggressive error grouping, auto-reopen on recurrence, and a dashboard that prioritizes new issues.

Honeybadger Pricing

Best For

Small bootstrapped teams that value signal over noise. Strong cron and background job monitoring.

---

8. LogRocket — Best for Frontend Visual Debugging

LogRocket records every user session as a video-like replay and layers error events on top. When a user reports a bug, you watch their session instead of reading a stack trace. This catches layout glitches, confusing UX flows, and timing-dependent bugs that traditional error tracking misses.

LogRocket Pricing

Best For

Frontend teams that debug through user behavior rather than stack traces. Error tracking is secondary to session replay in LogRocket's design.

---

9. SigNoz — Best OpenTelemetry-Native Alternative

SigNoz is an open-source observability platform built on OpenTelemetry from the ground up — errors, traces, logs, and metrics all flow through the same OTel pipeline and correlate by trace ID. Instead of a Sentry-compatible DSN, you instrument your app with standard OTel SDKs, so the same data feeds error tracking, distributed tracing, and dashboards without separate agents.

Pros

• Fully open source and self-hostable (ClickHouse-backed)
• Errors, traces, logs, and metrics unified under one OTel data model
• No vendor-specific SDK — standard OpenTelemetry instrumentation
• Usage-based cloud pricing avoids Sentry-style per-seat fees

Cons

• Requires OTel instrumentation, not a drop-in DSN swap for existing Sentry SDKs
• Self-hosting means operating ClickHouse — heavier than GlitchTip or Temps
• No session replay or uptime monitoring built in
• Younger error-tracking-specific tooling than Sentry's dedicated issue workflows

Best For

Teams already standardized on OpenTelemetry who want errors correlated with traces and logs in one open-source backend, and are comfortable operating ClickHouse.

---

10. HyperDX — Best for Correlating Errors With Logs and Traces

HyperDX (from the ClickStack/OTel ecosystem) centers on one search bar across logs, traces, metrics, and exceptions, so you can jump from an error straight to the surrounding log lines and the trace that produced it. Like SigNoz, it's OTel-native rather than a Sentry-DSN drop-in.

Pros

• Unified search across logs, traces, metrics, and errors
• Open source and self-hostable
• Session replay integration for frontend error context
• Built on the same OTel data model as the rest of your observability stack

Cons

• Requires OTel instrumentation — no Sentry SDK compatibility
• Self-hosting requires running the ClickHouse-based stack
• Smaller ecosystem of framework-specific integrations than Sentry
• No built-in uptime monitoring or deployment tooling

Best For

Teams debugging production issues by pivoting between logs, traces, and errors, who want that correlation without stitching together separate tools.

---

11. Grafana + Faro + Pyroscope — Best If You're Already on Grafana

Grafana's observability stack extends beyond dashboards: Faro handles frontend error and RUM collection, Pyroscope adds continuous profiling, and Grafana correlates all of it with Loki logs and Tempo traces. For teams that already run Grafana for metrics, adding error tracking means extending an existing stack instead of adopting a new vendor.

Pros

• Extends an observability stack many teams already run
• Correlates errors with metrics (Mimir/Prometheus), logs (Loki), and traces (Tempo)
• Fully open source and self-hostable
• Continuous profiling (Pyroscope) goes beyond what Sentry offers natively

Cons

• Requires assembling and operating multiple components (Faro, Loki, Tempo, Pyroscope, Mimir)
• Steeper setup than a single Sentry-compatible DSN swap
• Error-specific workflows (issue grouping, assignment) are less mature than Sentry's or GlitchTip's
• Best suited to teams with existing Grafana operational expertise

Best For

Teams already invested in the Grafana ecosystem who want to add error tracking and frontend RUM without introducing a separate vendor.

---

Which Sentry Alternative Should You Pick?

The core question: are you paying to fix bugs, or paying just to know bugs exist? Per-event pricing models (Sentry, Bugsnag, Rollbar) charge you more the worse your production is behaving. GlitchTip and Temps eliminate per-event pricing entirely, and the OTel-native stacks (SigNoz, HyperDX, Grafana) charge usage-based cloud rates but are free to self-host. If you're also paying for separate analytics, session replay, and uptime monitoring, Temps eliminates those bills too — the OTel stacks solve error-trace-log correlation but don't bundle deployments or uptime the way Temps does.

Frequently Asked Questions

What are the best self-hosted alternatives to Sentry for error tracking in 2026?

The best self-hosted alternatives to Sentry for error tracking in 2026 are Temps, GlitchTip, SigNoz, HyperDX, and the Grafana + Faro + Pyroscope stack. Temps leads because it is the only one of the five that exposes a Sentry-compatible DSN and bundles analytics, session replay, uptime, and deployments — point your existing Sentry SDK at your Temps instance by changing one DSN URL, and your error data stays on your own server (free to self-host, ~$6/mo on Temps Cloud, Apache-2.0). GlitchTip is the lightest pure-error drop-in, running on 512MB of RAM under an MIT license. Highlight.io was the heavier full-stack open-source option, but its hosted service sunset on February 28, 2026 after the LaunchDarkly acquisition — the product now lives inside LaunchDarkly Observability, and the open-source repo, while still public, is no longer developed as a standalone product. If your team is already standardized on OpenTelemetry, SigNoz and HyperDX are the leading self-hosted OTel-native options — they unify errors with traces and logs under one pipeline, though both require OTel instrumentation rather than a Sentry DSN swap. Teams already running Grafana can extend it with Faro (frontend errors/RUM) and Pyroscope (profiling) instead of adopting a separate error tracker. The tradeoff across all three OTel-native tools: no per-seat SaaS fees when self-hosted, but none of them bundle deployments or uptime monitoring the way Temps does.

What is Sentry's pricing in 2026?

Sentry's free Developer plan caps at 5,000 errors/month with 1 user. The Team plan starts at $26/month billed annually (50,000 errors, unlimited users). The Business plan starts at $80/month with the same 50,000-error quota. Session replay is included on all plans but capped at 50 replays/month — errors and replays beyond the included quotas bill pay-as-you-go.

Can I migrate from Sentry without changing my code?

GlitchTip and Temps are both Sentry-SDK-compatible: each exposes a Sentry-compatible DSN endpoint, so you change a single configuration URL and keep using the official Sentry SDK — @sentry/react, @sentry/node, sentry-python, or any of the 100+ other Sentry SDKs. No code modifications needed. Highlight.io (now LaunchDarkly Observability) requires switching to its own SDK, which typically takes 30–60 minutes per service. SigNoz, HyperDX, and Grafana's stack are OTel-native rather than Sentry-compatible — they need standard OpenTelemetry instrumentation instead of a DSN swap, which is more work upfront but pays off if you want errors correlated with traces and logs under one vendor-neutral standard.

What is the best free Sentry alternative?

For self-hosted: Temps, GlitchTip, SigNoz, HyperDX, and Grafana's stack are all completely free with no event limits when you run them yourself. Temps adds analytics, session replay, and deployments; GlitchTip is lighter and simpler; SigNoz, HyperDX, and Grafana require OTel instrumentation but unify errors with traces and logs. For managed SaaS: Bugsnag's free tier (7,500 events/month) is the most generous, followed by Rollbar and Honeybadger (5,000/month each) and LogRocket (1,000 sessions/month).

How much can I save by switching from Sentry?

A team on Sentry Team pays $26/month for just 50,000 included errors — every error past the quota bills pay-as-you-go. GlitchTip's hosted Small plan is $15/month for 100,000 events — double the quota at roughly half the price. Self-hosting GlitchTip or Temps drops software cost to $0, with only VPS costs (~$6/month on Hetzner). If you're also paying for separate analytics, session replay, and uptime monitoring, consolidating with Temps saves $200–400/month compared to a typical SaaS stack.

Is self-hosted error tracking reliable enough for production?

Yes. GlitchTip runs on 512MB of RAM and handles millions of events monthly. Temps processes errors alongside deployments, analytics, and session replay on a single server. The key responsibility shift is that you handle backups, updates, and infrastructure — the same tradeoff as any self-hosted service.

What is the Sentry free plan limit in 2026?

Sentry's free Developer plan limits you to 5,000 errors per month with 1 user (50 session replays included). Paid tiers start at $26/month (Team plan, 50,000 errors, unlimited users) and $80/month (Business plan, same 50,000-error quota), both billed annually, with pay-as-you-go pricing beyond the included volumes.
