The product
Six capabilities, one platform, no dashboards to live in. The short version is below; the full detail is in the docs.
Monitoring
Logs, traces, and metrics over standard OpenTelemetry, no proprietary agent. Auto-instrumentation covers your framework, your database, and your outbound calls, and LLM calls show up as spans in the same trace. Any language OpenTelemetry speaks, Fixter speaks.
docs: telemetry →Debugging
Query your telemetry from Claude Code, Cursor, or any MCP client. Ask what broke, get the answer with evidence. Prefer clicking? The app has live tail and search. Prefer SQL? That works too.
docs: debugging →Alerting
Define alerts in plain language, and Fixter previews each rule against your real history before you save it. Meanwhile its own detectors run from day one: error bursts, anomalies against learned baselines, error budget burn. Everything lands in Slack, only when it matters.
docs: alerting →Investigations
An alert lands in a Slack channel Fixter watches, and an AI agent investigates on the spot: it queries your logs and traces and replies in the thread with the root cause, who is affected, and what to do. Pull it into Claude Code with one command and finish the fix, or let Fixter open a ready for review pull request (beta).
docs: investigations →Issues
Errors and exceptions are captured and grouped by root cause: one line per problem, with counts and affected users, not a thousand duplicates. And because issues live in the same telemetry as your logs, traces, and metrics, each one links straight to its trace. More than exception tracking, and no separate tool to run.
Uptime monitoring
Scheduled probes hit your endpoints from the outside, down to every 30 seconds, with uptime and latency tracked over time. So you catch an outage even when there is no traffic. And it is not just HTTP: Fixter probes your MCP servers the way an agent would call them, handshake, tools and all.
docs: uptime, API & MCP testing →Trust
Your code stays yours.
Monitoring and alerting run entirely on the telemetry you send. They never touch your code. Investigations work on telemetry alone too, but grant them read access and they get sharper: the agent sees the code paths behind the failure and hands you a fix that actually fits your codebase. Your repository is cloned into a secure sandbox, used only to solve that problem, and deleted right after.
