Fakechat

This plugin provides a zero-dependency local chat UI for testing notification and messaging flows. It runs entirely on localhost, does not require API tokens or external services, and starts from a single command. You get a lightweight web UI that reads and displays messages, lets you type replies, and records message history to local files so you can replay scenarios.

It creates mock endpoints and a local receiver so you can POST messages, simulate webhooks, and inspect incoming payloads and headers in real time. The UI shows timestamps, sender IDs, and raw JSON for each message. You can configure fake users, preset system messages, and send batches of messages to exercise retries, rate limits, or formatting edge cases.

The tool logs all traffic to disk and shows a searchable history so you can trace a notification from send to display without flipping between logs and mail clients. It runs on a single machine and opens a browser tab for quick manual verification and exploratory testing.

Imagine working on a mobile app notification flow: you can run the local server, trigger webhooks from your backend, watch messages appear, tweak payloads, and verify client behavior without deploying or swapping between a staging server and a third-party sandbox. That saves time and keeps work focused on the message formats and error paths you care about.
