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 Rust binary with no per-seat, per-event, or bandwidth fees.
Temps is also the only entry here that is a deployment platform, so it links every error to the deployment SHA that introduced it. Free to self-host under the Apache 2.0 license, or ~$6/mo on Temps Cloud (Hetzner cost + 30%).
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 Rust binary. A 5-person team paying ~$378/mo across separate SaaS observability tools drops to ~$6/mo on Temps Cloud, or $0 self-hosted (temps.sh, June 2026).

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, June 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.
| Tool | Type | Pricing model | Per-seat fee | Per-event fee | Self-hosted footprint | Sentry SDK compatible | Bundled observability | Cost (5-person team) |
|---|---|---|---|---|---|---|---|---|
| Temps | Bundled PaaS | Flat / VPS-only | No | No | Single Rust binary | Yes (DSN swap) | Analytics + replay + uptime + deploys | ~$6/mo or free |
| GlitchTip | Open source | Flat / hosted tiers | No | No (self-host) | ~4 containers, 512MB RAM | Yes (DSN swap) | None | Free or $15/mo hosted |
| Self-hosted Sentry | Open source | Free (infra heavy) | No | No (self-host) | 40+ containers, 16GB RAM | Yes (native) | Errors + tracing only | Free + heavy infra |
| Bugsink | Self-hosted | Flat / hosted tiers | No | No (self-host) | 1 container, SQLite default | Yes (DSN swap) | None | Free or EUR16+/mo hosted |
| Discontinued | N/A | N/A | N/A | ClickHouse (shut down) | Own SDK | Errors + replay (gone) | Migrate off |

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.
Temps charges no per-seat, per-contributor, or per-event fee — it's free to self-host under the Apache 2.0 license, or ~$6/mo on Temps Cloud (Hetzner cost + 30%). That ~$6 covers a typical SaaS stack that runs about $378/mo: error tracking, analytics, session replay, uptime monitoring, and deployments (temps.sh, June 2026). One binary, one bill, 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.
Temps is the deployment platform, so it does something GlitchTip, Bugsink, and self-hosted Sentry structurally cannot: it links every error to the deployment SHA that introduced it. When a new release spikes your error rate, Temps already knows which commit shipped it.
It goes further with auto-rollback. Health checks poll every 5 seconds and need 2 consecutive successes to mark a deployment healthy; if HTTP errors persist for 60 seconds, the proxy route reverts automatically. That's verified behavior in crates/temps-deployments/src/jobs/deploy_image.rs. A standalone tracker can tell you production is on fire — Temps can put the fire out and roll you back.
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 can't justify a separate $100/mo deploy tool, a $99/mo replay tool, and a $26/mo error tool. Temps collapses all of them.
| Capability | Temps |
|---|---|
| Per-seat / per-contributor fee | None |
| Per-event pricing | None |
| Sentry SDK compatible | Yes (one-URL DSN swap) |
| Error → deployment SHA linking | Yes |
| Auto-rollback on error spike | Yes (5s poll, 60s revert) |
| Bundled analytics / replay / uptime | Yes |
| Self-hosted footprint | Single Rust binary |
| Cost (5-person team) | ~$6/mo or free |
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 yet: A smaller SDK catalog than Sentry's 100+ platforms, and a younger community. If you need niche language SDKs or enterprise SSO today, weigh that — SSO/SAML ships in Temps EE.
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 a Django + Celery + PostgreSQL + Redis stack — roughly 4 containers, versus self-hosted Sentry's 40-plus. 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.
The official self-hosted Sentry has no license fee and no per-seat billing, but it spins up 40+ Docker containers and documents a 16GB RAM minimum. You get PostgreSQL, ClickHouse, Kafka, Zookeeper, Redis, Snuba, Symbolicator, relay, and a fleet of workers — the full SaaS feature set, operationally expensive (github.com/getsentry/self-hosted, June 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.
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.
Highlight.io's standalone open-source product shut down on February 28, 2026, after the team's LaunchDarkly acquisition, so it's no longer a viable self-hosted error tracker. Most competitor roundups still list it as a top open-source pick — that's now outdated. The project had 10,000+ GitHub stars and a ClickHouse-powered architecture, but the standalone service folded into LaunchDarkly Observability (github.com/highlight/highlight, June 2026).
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. We're flagging it explicitly because stale "best of" lists keep sending teams toward a product that no longer exists in self-hostable form.
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 overage runs about $0.000290/event (sentry.io/pricing, June 2026).
Let's be precise, because the per-seat framing is widely misstated. Sentry's Developer tier is free (5,000 errors, 1 user, 30-day retention). Team is $26/mo with unlimited users; Business is $80/mo with SSO and audit logs. 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. For a deeper Sentry-pricing breakdown, see our 8 best Sentry alternatives guide.
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 Rust binary, and charges no per-seat, per-contributor, or per-event fee. Free self-hosted, or ~$6/mo on Temps Cloud. 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.
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 it links every error to the deployment SHA that introduced it and can auto-rollback a bad deploy (5s health polls, 60s revert). Coolify and Dokploy deploy apps but have no built-in error tracking at all.
No — Sentry's base Team ($26/mo) and Business ($80/mo) plans have unlimited users and are event-based, not per-seat (sentry.io/pricing, June 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.
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.
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.
A 5-person team running separate observability SaaS — Sentry, analytics, session replay, uptime, and deployments — typically spends around $378/mo (temps.sh, June 2026). Consolidating onto self-hosted Temps drops that to ~$6/mo on Temps Cloud, or $0 plus VPS cost when fully self-hosted. You also eliminate the $40/contributor Seer add-on and every per-event overage.
Yes — Temps is the only self-hosted PaaS that bundles deployment, web analytics, session replay, error tracking, and uptime monitoring in one Rust binary. Deployment-only platforms like Coolify, Dokploy, Dokku, and CapRover ship none of the observability layer, so teams on those tools still pay separately for error tracking (Sentry, GlitchTip, Bugsink) and everything else. Temps collapses that stack into a single self-hosted install with no per-seat fee anywhere in it.
