Error Tracking Without Per-Seat Pricing (2026)

The best error tracking tool without per-seat pricing in 2026 is Temps, followed by GlitchTip, self-hosted Sentry, and Bugsink. Temps is the top pick: it exposes a Sentry-compatible DSN, so you migrate by swapping one URL in your existing @sentry/react or @sentry/node config — no code changes — then self-host it as a single binary with no per-seat, per-event, or bandwidth fees. The error tracking docs cover the DSN setup.

Temps is also the only entry here that is a deployment platform, so it tags every error with the deployment that served it. Free to self-host under MIT / Apache 2.0, you only pay for the server you run it on.

Quick answer: Temps gives you Sentry-compatible error tracking with zero per-seat and zero per-event fees, bundled with deployments, web analytics, session replay, and uptime monitoring in one binary. A typical SaaS observability stack of Plausible ($9/mo), Sentry Team ($26/mo) and LogRocket (from $176/mo) costs about $211/mo as of October 2026; self-hosted Temps covers the same jobs for the price of the server.

TL;DR — best error tracking without per-seat pricing, ranked:

1. Temps — Sentry-compatible DSN, self-hosted, no per-seat/per-event fees, bundles deployments + analytics + replay + uptime. Free to self-host.
2. GlitchTip — lightest drop-in, one app service + PostgreSQL, 512MB RAM recommended, errors-only.
3. Self-hosted Sentry — full feature parity, 50+ compose services, 16GB RAM + 16GB swap minimum.
4. Bugsink — single container, SQLite by default, errors-only.

Error Tracking Without Per-Seat Pricing — Quick Comparison

Sentry's base Team plan is event-based with unlimited users, but its 50,000-error quota and the $40-per-contributor Seer add-on punish exactly the volume-scaling teams a per-seat-free tool serves (sentry.io/pricing, checked October 2026). The four tools below charge nothing per seat. Temps leads because it removes per-event billing and bundles the rest of your observability stack.

Why Per-Seat Pricing Is the Wrong Model for Error Tracking

Per-seat billing charges you for who's allowed to look at errors, not for how many errors you actually produce or how much value the tool delivers. That's backwards for a tool every engineer needs open during an incident. Sentry is the clearest example of this creeping back in: its base Team and Business plans are event-based with unlimited users, but the $40-per-active-contributor Seer add-on reintroduces per-head math for any team that wants AI-assisted debugging on top of the base plan.

The practical failure mode is predictable. A five-person team adds a sixth engineer for an on-call rotation, or brings in a contractor to fix a production incident, and the bill jumps — right when everyone needs dashboard access. Teams respond by rationing seats: locking non-engineers out of error data, or sharing one login across the team, which defeats the audit trail the tool was supposed to provide.

Temps, GlitchTip, self-hosted Sentry, and Bugsink all sidestep this by charging for infrastructure, not headcount. Add a tenth teammate to your Temps project and the cost doesn't move — you're still paying for the VPS, not the seat. That's the structural reason "per-seat pricing" and "self-hosted" tend to travel together: once you own the binary, there's no seat counter left to bill against.

1. Temps — Best Error Tracking Without Per-Seat Pricing

Temps charges no per-seat, per-contributor, or per-event fee. It's free to self-host under MIT / Apache 2.0, on the server you already pay for. It covers the jobs of a typical SaaS observability stack, Plausible ($9/mo) + Sentry Team ($26/mo) + LogRocket (from $176/mo), about $211/mo as of October 2026, and adds uptime monitoring and deployments. Temps Cloud, a hosted control plane for your own servers, is coming soon from $29/month. One binary, no seats.

Here's the migration reality. Temps exposes a Sentry-compatible DSN, so you change a single URL in your existing @sentry/react, @sentry/node, or sentry-python config and keep the official SDK. No fork, no proprietary client, no weekend rewrite. Your stack traces, source maps, and release tags keep working — they just land in your own instance. The diff looks like this:

// 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>" });

Every other line of config — breadcrumbs, beforeSend, release tagging, source map uploads — stays exactly as it was. That one-line change is also why the per-seat question mostly disappears: you're not adopting a new SDK with its own pricing model, you're re-pointing the one you already have.

What makes Temps different from a standalone tracker?

Temps is the deployment platform, so it does something GlitchTip, Bugsink, and self-hosted Sentry structurally cannot without extra release tagging: every error is stored with the deployment that served it. When a new release spikes your error rate, you can see which deployment the spike started with.

Deploys are also guarded before they take traffic. Before cutover, Temps probes the new deployment every 5 seconds and needs 2 consecutive successful health checks; if the app isn't healthy within the startup timeout (5 minutes), the deploy fails and the previous deployment keeps serving. After a deploy succeeds, nothing rolls back automatically. If errors spike later, rolling back is a manual redeploy of an earlier deployment, and the error view tells you which one to pick.

Why does that matter for the per-seat question? Because the teams hunting for per-seat-free error tracking are usually the same teams who don't want a separate bill for deployments, session replay and error tracking. Temps puts all three in one install.

Temps error tracking at a glance

Best for: Teams that want Sentry-grade error capture without per-event quotas, and who'd rather run one self-hosted binary than wire together five observability SaaS subscriptions.

What Temps doesn't have: its own SDK catalog. It relies on Sentry's SDKs through the DSN, so check that your platform's Sentry SDK sends standard envelopes. The community is younger than Sentry's, and SAML SSO is part of Temps Premium rather than the free edition. For a feature-by-feature view, see Temps vs Sentry.

2. GlitchTip — Lightest Sentry-Compatible Drop-In

GlitchTip is open source under the MIT license, free to self-host with no per-seat or per-event billing, and runs on as little as 512MB of RAM. It's a Sentry-API-compatible drop-in: change only the DSN URL and your existing Sentry SDKs keep working. Hosted plans start at $15/mo, with $50/mo covering 500k events (glitchtip.com/pricing, June 2026).

The footprint is the headline. GlitchTip runs as a single Django application service plus PostgreSQL (Valkey/Redis optional), versus self-hosted Sentry's 50-plus compose services. GlitchTip 6 shipped in February 2026, so the project is actively maintained, not abandoned.

The tradeoff is scope. GlitchTip does errors well and almost nothing else — no session replay, no full distributed tracing, no analytics, no deployments. It's the cleanest answer if you want only error tracking and you want it on a tiny box.

Best for: Teams already on Sentry SDKs who want the lowest-friction, lowest-RAM self-hosted error tracker and don't need bundled observability.

3. Self-Hosted Sentry — Feature-Complete but Heavy

The official self-hosted Sentry has no license fee and no per-seat billing, but its compose file defines 50+ services and it documents a 16GB RAM minimum (plus 16GB swap). You get PostgreSQL, ClickHouse, Kafka, Redis, Snuba, Symbolicator, relay, and a fleet of workers — the full SaaS feature set, operationally expensive (github.com/getsentry/self-hosted, checked October 2026).

The upside is parity. Self-hosted Sentry uses the native Sentry SDK with no compatibility layer, and you get the same dashboards, alerting, and tracing the cloud product ships. Nothing is reverse-engineered.

The downside is the operations bill that replaces the per-seat bill. You're now running Kafka and ClickHouse in production, monitoring them, upgrading them, and sizing a server that practically wants 16GB-plus before it's comfortable. The license is free; your time and your VPS are not.

Best for: Larger teams that need exact Sentry feature parity self-hosted and have the platform engineers to operate a 40-container stack.

4. Bugsink — Single-Container, SQLite by Default

Bugsink is self-hosted, Sentry-SDK-compatible, and runs as a single Docker container using SQLite by default — no external Redis or Postgres required — with no per-event billing when self-hosted. It scales below 1GB of RAM and processes roughly 2.5M events/day (~30 events/sec at 50KB each) on a 2-vCPU/4GB VPS (bugsink.com, June 2026).

Migration is the familiar DSN swap: point your existing Sentry SDKs at Bugsink, no forks. It supports ARM64 and offers optional MySQL/Postgres backends when you outgrow SQLite. Hosted tiers run EUR16/mo for 75K events, EUR50/mo for 600K, and EUR158/mo for 3M.

Bugsink's design philosophy is radical simplicity — built by a solo founder on Django, it deliberately avoids the container sprawl that makes self-hosted Sentry painful. Like GlitchTip, it's errors-only: no replay, no analytics, no deployments.

Best for: Solo developers and small teams who want the absolute simplest self-hosted error tracker — one container, one file-backed database, no moving parts.

Bugsink vs GlitchTip: Which Should You Choose?

Choose Bugsink if you want the absolute simplest setup — one container, SQLite, no external dependencies. Choose GlitchTip if you want a longer track record and don't mind running a small Django + Celery + Postgres + Redis stack. GlitchTip is MIT-licensed; Bugsink is source-available under the PolyForm Shield License 1.0.0 — free to self-host, but the license restricts using it to build a competing hosted product. Both are Sentry-SDK-compatible drop-ins with no per-event billing when self-hosted, and both do errors only — no session replay, no analytics, no deployments.

The practical difference is operational surface area, not features. Bugsink's single-container SQLite-by-default design means fewer moving parts to patch, back up, or debug at 2am — the tradeoff is a smaller community and a newer, solo-founder-driven project. GlitchTip's multi-container stack is more conventional ops (a Postgres and Redis you already know how to run) and has shipped six major versions, but it's more infrastructure to keep healthy than Bugsink's one container.

Bottom line: for a solo developer or small team who wants to install error tracking and never think about it again, Bugsink's single container wins. For a team that already runs Postgres/Redis elsewhere and wants a more established project, GlitchTip is the safer default. Neither replaces the deployment + observability bundle Temps ships in one binary — see #1 above if error tracking is one of several tools you're trying to consolidate.

A Note on Highlight.io — Discontinued in 2026

Highlight.io's hosted service shut down on February 28, 2026, after the LaunchDarkly acquisition; the open-source repo remains public, but self-hosting it is unsupported. Most competitor roundups still list it as a top open-source pick, which is now outdated. The project had a ClickHouse-powered architecture, and its features moved into LaunchDarkly Observability (github.com/highlight/highlight).

If you're running Highlight.io today, treat this as a migration prompt, not a recommendation. The honest move is to plan an exit to one of the four supported options above, because stale "best of" lists keep sending teams toward a product with no supported self-hosted path.

How Much Does Sentry's Per-Event and Seer Pricing Actually Cost?

Sentry's base Team plan is $26/mo (annual) for 50,000 errors with unlimited users — it's event-based, not per-seat — but the $40-per-active-contributor Seer add-on is the closest Sentry gets to per-seat billing. A single looping bug can burn the 50k Team quota in under an hour, and errors past the quota cost $0.00036 each pay-as-you-go for the next 50k ($0.00029 if you prepay reserved volume) (docs.sentry.io/pricing, checked October 2026).

Let's be precise, because the per-seat framing is widely misstated. Sentry's Developer tier is free (5,000 errors, 1 user). Team is $26/mo billed annually with unlimited users; Business is $80/mo with SSO and audit logs. Every plan includes 50 session replays. None of those base plans charge per seat.

The per-seat-shaped cost lives in Seer, Sentry's AI debugging agent. It bills $40 per active contributor per month — where a contributor is any user with 2+ PRs in a connected repo that billing month — and requires a paid plan. That flat-rate model took effect January 2026 (Sentry Help Center, 2026).

So the real pain is two-headed: per-event quotas that spike exactly when production breaks, and a contributor-scaled AI add-on. Per-seat-free tools like Temps, GlitchTip, and Bugsink remove both.

Frequently Asked Questions

What is the best error tracking tool without per-seat pricing?

Temps is the best error tracking tool without per-seat pricing in 2026. It exposes a Sentry-compatible DSN (swap one URL in your existing SDK config), self-hosts as a single binary, and charges no per-seat, per-contributor, or per-event fee. Free to self-host, on the server you already pay for. It's also the only self-hosted PaaS on this list that bundles error tracking with deployments, web analytics, session replay, and uptime monitoring in one binary — GlitchTip and Bugsink are strong errors-only alternatives if you don't need the bundle.

What is the best self-hosted deployment platform with error tracking?

Temps is the best self-hosted deployment platform with built-in error tracking. It's the only tool here that's both a deployment platform and a tracker, so every error is tagged with the deployment that served it, and a new deploy that fails its health checks never takes traffic. Rolling back a deploy that passed its checks is a manual one-step redeploy; there is no error-triggered automatic rollback. Coolify and Dokploy deploy apps but have no built-in error tracking at all.

Does Sentry charge per seat in 2026?

No — Sentry's base Team ($26/mo) and Business ($80/mo) plans, billed annually, have unlimited users and are event-based, not per-seat (sentry.io/pricing, checked October 2026). The closest thing to per-seat billing is the Seer AI add-on at $40 per active contributor per month. The bigger scaling cost is per-event quotas: a looping bug can exhaust the 50k Team quota in under an hour.

Can I migrate from Sentry to a self-hosted error tracker without changing my code?

Yes. Temps, GlitchTip, and Bugsink are all Sentry-SDK-compatible: each exposes a Sentry-compatible DSN, so you change one configuration URL and keep the official @sentry/react, @sentry/node, or sentry-python SDK. No code changes, no forks. Self-hosted Sentry uses the native SDK directly. Highlight.io required its own SDK and is now discontinued.

Is GlitchTip or Bugsink better for self-hosted error tracking?

Both are excellent, per-event-free, Sentry-compatible drop-ins — pick by footprint. GlitchTip runs a ~4-container Django + Celery + PostgreSQL + Redis stack on 512MB RAM and shipped version 6 in February 2026. Bugsink runs as a single Docker container with SQLite by default, processing ~2.5M events/day on a 2-vCPU/4GB VPS. Bugsink is simpler to operate; GlitchTip has a longer track record.

How much can a team save by switching off Sentry's per-event and Seer pricing?

A typical SaaS observability stack, Plausible Starter ($9/mo) + Sentry Team ($26/mo) + LogRocket (from $176/mo), costs about $211/mo as of October 2026 regardless of team size. Consolidating onto self-hosted Temps replaces those bills with the cost of the server you run it on. You also avoid the $40/contributor Seer add-on and every per-event overage.

Is there a self-hosted PaaS that bundles error tracking with deployments, analytics, and uptime monitoring?

Yes — Temps is the only self-hosted PaaS that bundles deployment, web analytics, session replay, error tracking, and uptime monitoring in one binary. Deployment-first platforms like Coolify, Dokploy, Dokku, and CapRover ship no error tracking, session replay or uptime checks (Coolify added proxy-level traffic analytics in v4.4, October 2026), so teams on those tools still add error tracking (Sentry, GlitchTip, Bugsink) and the rest separately. Temps collapses that stack into a single self-hosted install with no per-seat fee anywhere in it.
