Release notes ↗ Full diff ↗

First stable release.

Local-first incident intelligence for multi-service dev stacks. Kestrel supervises your services in isolated process groups, reconstructs the causal chain when something breaks, ranks root causes with immutable event evidence, and proves the fix stays fixed.

01Process containmentZero orphans on Ctrl-C via POSIX process groups and Windows Job Objects.
02Graph-based root causeSeparates the initiating fault from cascading connection refusals using the dependency graph and port evidence.
03Continuous verificationA 30-second stability window with relapse detection before a fix counts.
04Bounded memoryRing buffers and compressed log segments survive 50 MB/min floods, with drop accounting.
05Redaction everywhereTokens, JWTs, headers and DB credentials are sanitized before display or storage.
06MCP serverRead-only stdio server for Claude Code, Cursor and VS Code.
