Self-Hosted Error Tracker: Self-hosted error tracking tool built with Rails

What it does

Telebugs is a self-hosted error tracking system designed as an alternative to Sentry. It accepts Sentry SDK events, so applications can report errors using the same SDKs they already use. The only change required is updating the DSN (data source name) to point to a Telebugs instance instead of Sentry's cloud service. The tool collects errors, groups related reports together, prioritizes issues by frequency, and sends alerts via push, email, Slack, Discord, Teams, or webhooks. It displays backtraces, breadcrumbs, request details, local variables, and custom context. Resolved errors remain tracked and reopen automatically if the issue occurs again.

Who it is for

Telebugs targets teams running applications that already use Sentry SDKs but want to keep error data on their own infrastructure. The product appeals to organizations uncomfortable with cloud-hosted error tracking for compliance, privacy, or data sovereignty reasons. It is also relevant to teams frustrated with the operational overhead of self-hosted Sentry, which requires managing multiple services and dependencies.

Pricing

How it stands out

The core differentiation is simplicity through focus. While self-hosted Sentry includes observability features beyond error tracking (performance monitoring, code coverage, and more), Telebugs deliberately omits these features. The product runs as a single container rather than a distributed system of services. This reduces the infrastructure required to monitor and upgrade the system. The creator built this after years at BugSnag and Airbrake, so the interface is described as polished. Telebugs maintains SDK compatibility with Sentry, meaning teams do not need to change application code or remove existing instrumentation.

What a founder should check

Prospective builders should verify how many teams actually find self-hosted Sentry's operational burden prohibitive enough to justify switching. The creator claims to have already sold copies, but the total addressable market for self-hosted error tracking versus cloud alternatives remains unclear. Second, switching costs matter: even though Telebugs accepts Sentry SDKs, teams must migrate historical error data, reconfigure alerting rules, and adjust workflows. Understanding what percentage of prospects complete this migration is important. Third, the moat is narrow. Sentry could simplify its self-hosted offering or release a lightweight edition, and any cloud-based observability platform could add a self-hosted option. The single-container architecture is not proprietary. Pricing pressure from Sentry or open-source competitors should be evaluated.
