Self-Hosted Sentry Alternative | One Container | Telebugs
A lighter alternative to self-hosted Sentry for error tracking
Self-hosted Sentry gives you the full platform on your own infrastructure. Telebugs gives you the narrower path: Sentry SDK compatible error tracking, one Docker container, MCP, and a one-time license. Run the error tracker, not an observability platform.
Telebugs keeps the focus narrow and the experience simple. It offers one project setup screen and one lightweight service.
Quick answer: is Telebugs a good self-hosted Sentry alternative?
Yes, if your team mainly needs error tracking: exceptions, grouping, stack traces, breadcrumbs, releases, notifications, notes, retention, and a debugging workflow your developers can trust. Telebugs keeps the Sentry SDK migration path but replaces the full self-hosted Sentry stack with one focused application.
- Choose Telebugs when you want a lighter self-hosted error tracker with Sentry SDK compatibility and predictable pricing.
- Choose self-hosted Sentry when you need the broader Sentry platform on your own infrastructure and have the operations capacity to run it.
- Choose hosted Sentry when you want Sentry to operate the platform and you are comfortable with hosted pricing, data location, and account model.
In other words, Telebugs is not trying to be a self-hosted copy of every Sentry product. It is a self-hosted Sentry alternative for teams that want the error tracking workflow without the full platform footprint.
What official self-hosted Sentry requires
Sentry's self-hosted docs make the tradeoff clear. You can run Sentry on your own server, but you are running the Sentry platform, not just a small error inbox.
- Support model: Sentry says the self-hosted setup has no guarantees or dedicated support, with community support expected for most questions.
- Install path: Sentry recommends cloning the self-hosted repository, running
./install.sh, and starting the stack withdocker compose up --wait. - Minimum resources: Sentry lists 4 CPU cores, 16 GB RAM plus 16 GB swap, and 20 GB free disk space, with 32 GB RAM recommended.
- Disk I/O: Sentry notes that self-hosted deployments rely heavily on disk I/O because databases, message brokers, and other services run on one machine.
- Production setup: Sentry recommends a dedicated load balancer, TLS termination, health checks, URL-prefix configuration, and other production hardening.
- Scaling: Sentry says larger loads require more RAM and disk, and that scaling further likely means Kubernetes or another more complex tool.
- Licensing: Sentry documents current self-hosted code as Fair Source/FSL, not OSI open source for the current version.

The reality of self-hosting Sentry
Many teams start with official self-hosted Sentry because they want to keep error data on their own infrastructure and avoid hosted usage bills. The intention is reasonable. The operational surface is the part to evaluate carefully.
- The stack includes infrastructure components such as PostgreSQL, Redis, Kafka, pgbouncer, ClickHouse, Snuba, SeaweedFS, Symbolicator, Relay, workers, and web services.
- The docs describe self-hosted as a blueprint for how Sentry services connect, which is useful if you are willing to maintain a larger custom installation.
- Even when you own the data location, you still need to decide how to handle monitoring opt-in, beacon settings, external integrations, backups, retention, proxying, TLS, and upgrades.
- Some SaaS-side features are not available in self-hosted Sentry, including billing-tied features, Seer and other closed-source AI/ML features, and Sentry's hosted data storage location controls.
That may be exactly what you want if you need the complete platform. If you mostly need exceptions, grouping, stack traces, breadcrumbs, releases, notifications, notes, and retention, Telebugs keeps the useful Sentry SDK path while shrinking the backend to one focused application.
Hosted Sentry vs self-hosted Sentry vs Telebugs
| Question | Hosted Sentry | Self-hosted Sentry | Telebugs |
|---|---|---|---|
| Best fit | Managed observability with minimal infrastructure work. | Full Sentry platform on infrastructure you operate. | Focused self-hosted error tracking with a smaller operational footprint. |
| Operations | Sentry runs the service. | You run the full multi-service stack. | You run one Docker container. |
| SDK migration | Native Sentry SDK backend. | Native Sentry SDK backend. | Sentry SDK compatible. Change the DSN and keep the client setup. |
| Data control | Hosted account and vendor-managed infrastructure. | Your infrastructure, with the full platform stack. | Your infrastructure, focused on error tracking data. |
| AI workflow | Sentry's hosted AI features and integrations. | Self-hosted Sentry features, with hosted-only AI/ML differences documented by Sentry. | MCP support so approved AI coding tools can inspect Telebugs error context. |
| Support model | Hosted product support depends on plan. | Sentry documents no dedicated support for self-hosted. | Email support included with every Telebugs purchase. |
| Primary tradeoff | Least operations, hosted usage billing and vendor-managed data. | Maximum Sentry platform control, highest maintenance surface. | Focused error tracking control, much smaller maintenance surface. |
How Telebugs is different by design
Telebugs was built from the ground up with a different goal: give teams the core capability they actually need (collect, group, and get notified about errors) without forcing them to run an entire observability platform.
| Aspect | Self-hosted Sentry (typical) | Telebugs |
|---|---|---|
| Architecture | Multi-service Docker Compose stack with databases, brokers, storage, workers, Relay, Symbolicator, Snuba, and more. | Single Docker container |
| Install | Clone repo, run ./install.sh, then run Docker Compose. |
One command (handles Docker + TLS cert if needed) |
| Minimum hardware | 4 CPU cores, 16 GB RAM + 16 GB swap (32 GB recommended) per official docs | Runs well on 1–2 GB / 1–2 cores (see table on homepage) |
| Small hardware | Sentry recommends substantially more RAM and disk than a small error-tracking-only backend. | Full ARM64 Docker support |
| Updates | Manual self-hosted upgrades and operational coordination. | Automatic within major version; optional manual |
| Cost model | Free software + your infra + your time | $299 USD once, no Telebugs event quotas |
| Scope | Full observability platform (errors + performance + more) | Focused error tracking, done well |
| Commercial support | Sentry documents no guarantees or dedicated support for self-hosted. | Included email support. |
These comparisons are based on Sentry’s official self-hosted documentation and public self-hosted Docker Compose file. Individual needs still vary depending on event volume, retention settings, attachments, integrations, and the observability features you enable.
We also made specific engineering choices that help on real hardware. For example, the ingestion pipeline is designed so that large payloads do not bloat the job queue (see the detailed write-up of how we fixed a 95 GB queue problem that only surfaced because of how we use SQLite under the hood). That kind of operational thinking only happens when the system is small enough for one person to reason about end-to-end.
When self-hosted Sentry might still make sense
We are not saying self-hosted Sentry is always the wrong choice. There are situations where it is reasonable:
- You are a large organization that needs the full set of Sentry features (performance monitoring, profiling, session replays, etc.) and already has a dedicated platform/SRE team that can own the deployment.
- You have strict requirements that only the complete Sentry feature matrix satisfies today and you are willing to pay the operational cost.
- You are already deeply invested in the Sentry ecosystem (custom integrations, many plugins, advanced alerting rules) and the migration cost outweighs the simplification benefit for your team.
For most teams, especially small-to-medium engineering organizations, agencies, bootstrapped companies, or anyone who just wants reliable error tracking without building a second job, the cost/benefit math is different.
What you actually get with Telebugs
Telebugs is a complete, production-grade error tracking system that is intentionally smaller:
- Sentry SDK compatible error tracking. Change the DSN and your existing error-reporting integrations keep working (see the Sentry SDK compatible error tracking page).
- Automatic grouping with custom fingerprinting and manual merge when you need it.
- Releases and source map support so you can actually read production stack traces.
- Notifications via email, PWA push (installable on phones), and webhooks (Slack, Discord, custom).
- Collaboration tools: error notes, ownership, bulk actions, muting/snoozing with rules.
- Data retention policies you control, a full REST API, and the ability to run completely offline if needed. See the retention and compliance guide.
- MCP error tracking for AI coding tools, so approved clients can inspect error groups, reports, backtraces, breadcrumbs, and notes.
- A clean, fast UI built with Hotwire (very low JavaScript) that works well even on modest hardware.
One Telebugs license covers a single domain. You can track errors from as many projects and applications as that instance can handle. Telebugs does not bill per event; your practical limit is the server, storage, and retention policy.

Frequently asked questions
Is self-hosted Sentry worth it?
It can be worth it if you need the full Sentry platform, want it on your own infrastructure, and have the team capacity to operate the stack. If you mainly need error tracking, a focused self-hosted Sentry alternative like Telebugs can be much simpler.
What is a lighter alternative to self-hosted Sentry?
Telebugs is a lighter alternative when the job is production error tracking. It keeps Sentry SDK compatibility but runs as one Docker container instead of the full self-hosted Sentry service stack.
How much hardware does self-hosted Sentry need?
Sentry's self-hosted documentation lists minimum resources of 4 CPU cores, 16 GB RAM plus 16 GB swap, and 20 GB free disk space, with 32 GB RAM recommended. Actual needs depend on event volume, retention, disk I/O, and optional features.
Does self-hosted Sentry have dedicated support?
Sentry's self-hosted docs say self-hosted comes with no guarantees or dedicated support. For Telebugs, email support is included with every purchase.
Is self-hosted Sentry open source?
Sentry documents current self-hosted Sentry as Fair Source under the Functional Source License, not OSI open source for the current version. Telebugs is also not OSI open source; it is commercial software with source provided after purchase.
How much hardware do I really need for Telebugs?
Most small-to-medium workloads run comfortably on 1–2 GB of RAM and 1–2 CPU cores. The exact numbers depend on your error volume and retention settings. We publish rough scaling estimates on the homepage based on real measurements.
If you’ve been through the self-hosted Sentry journey and are looking for a lighter alternative, see our page on being tired of self-hosting Sentry.
Can I keep using Sentry SDKs with Telebugs?
Yes. Telebugs accepts Sentry SDK error events, so most app integrations can keep the same SDK setup and change the DSN to point at your Telebugs server.
Can I migrate from self-hosted Sentry to Telebugs?
Yes for new error reporting. Create a Telebugs project, copy the DSN, update one app or environment first, and verify a real test exception. Historical Sentry data does not automatically import, so most teams keep the old instance available temporarily for reference.
Can I run Telebugs on a cheap VPS or even a Raspberry Pi?
Yes. Many people run it on low-cost VPS providers (DigitalOcean, Hetzner, etc.) and on ARM devices. The Docker image supports ARM64 out of the box.
What happens when I need more features later?
Many teams never do. Focused error tracking solves the majority of “we don’t know what’s broken” problems. If you eventually need distributed tracing, profiling, or other observability signals, you can run Telebugs alongside another tool for those specific needs while keeping error tracking simple and unlimited.
Does Telebugs support MCP for AI debugging?
Yes. Telebugs supports MCP, so authorized AI coding tools can inspect structured error context from your Telebugs server, subject to the scopes and access you approve.
Is Telebugs open source?
No. It is commercial software with a one-time purchase model. You receive the full source after purchase and are free to modify it for your own use (subject to the license). We chose this model because it lets us focus on building one excellent, well-supported product without the pressures of open-source infrastructure maintenance at scale.
How do updates work?
Each installation phones home once per day to check for updates within the same major version. Updates are free. You can disable the check and update manually if you prefer. Major version upgrades (1.x → 2.x) are optional and may have a cost.
Want reliable error tracking without turning it into a second job?
Review installation expectations, compare pricing, or request a private demo. When you are ready, buy Telebugs and run it on your own server.
