Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Traceforge makes agent runs reproducible.
It records what actually happened across terminal, MCP, and browser tools, packages the run into a portable trace bundle, helps you inspect where it failed, and turns real failures into regression fixtures and tests.
Why
Modern agent workflows are powerful, but hard to trust.
- terminal output is incomplete
- MCP calls are buried in protocol logs
- browser failures are hard to reproduce
- expensive incidents rarely become tests
- teams fix failures once, then see them return later
Traceforge solves one narrow problem well:
capture -> inspect -> replay -> export test
It is not another agent framework. It is the verification layer for the agent ecosystem.
What You Get
- unified traces from terminal, MCP, and browser runs
- a local trace viewer with timeline, artifacts, and failure boundaries
- replay that re-runs a flow and checks where it diverges
- export to reusable regression fixtures and test templates
- shareable trace bundles for debugging and collaboration
