Errors found, fixed, shipped & verified in production

It watches production and sweeps your codebase, database & hosting — for the bugs you’ve hit and the ones you haven’t.

You set how far it goes, from suggestions to fully autonomous. Anything that fails its post-merge check reverts itself.

Start to finish

From your repo to a fix proved in production.

Illustrative workflow, covering the first three steps. You choose where the merge decision sits, and verification evidence reflects only the checks available for the change.

  4. It ships

    Merged to main — immediately, or after your approval. You set which.

  5. It proves the error is gone

    Checked against live production after the deploy. If that fails, the change reverts itself.

The project

Every fix on one board.

Each error stays linked to triage, branch work, available checks, and the reviewed pull request in one place — nothing hidden.

The To200 pipeline board — errors moving through Incoming, Analyzing, Planned, and Fixing toward a reviewed pull request.

Built to be trusted

Your autonomous reliability engineer.

Not another dashboard. To200 reads the failure, diagnoses a likely cause, writes a branch-only fix, runs available checks, and opens a pull request within the limits you set.

It shows its reasoning

Every task opens with a written assessment — root cause, the plan, and a confidence score. Read the why before anything ships.

It shows the evidence

To200 runs the checks available in the repository and attaches the results, assessment, and confidence to the pull request.

It ends at a change, not an explanation

An investigation ends when someone can explain the failure. To200 keeps going: a branch-only fix, the checks available in the repository, and a pull request carrying the assessment and verification evidence. What reaches review is a diff you can merge, not a diagnosis you still have to implement.

You set how far it goes

Choose when To200 may triage, write a repair branch, and open a pull request. Human review stays between the PR and main by default; Scale and High volume owners can deliberately enable merge-to-main under repository rules.
