Local browser verification for coding agents

TaskTape Replay

Reproduce the bug. Prove the fix. Keep the check.

Give Claude Code or Codex a visible browser it can control through MCP. TaskTape preserves the evidence, builds the bug report, and exports a Playwright check your team owns.

Apple Silicon beta. Local-only sessions. No account required.

Yours to keep Report, evidence, and Playwright code Runs on your Mac

One session preserves

From report to regression check

Your agent does the reproduction. You approve the truth.

TaskTape gives coding agents the browser tools they need while keeping the expected result under human control.

  1. 01

    Connect

    Add TaskTape as a local MCP server in Claude Code or Codex.

  2. 02

    Reproduce

    Your agent opens the local app and follows the bug from start to failure.

  3. 03

    Review

    Confirm what should happen before saving the regression check.

  4. 04

    Replay

    Run it in TaskTape or export ordinary Playwright code for your repository.

Proof you can inspect

A failed check shows where reality diverged.

Each replay keeps the expected result beside the observed browser state. Open the activity log for actions, screenshots, console output, requests, and the full trace.

  • Evidence stays on your machine
  • Expected outcomes require review
  • Exported tests run without an LLM
  • Every replay keeps a run record
