peep() from any code

Send any value with colors, labels, tables, JSON, timing, traces, counters and pause. Plain PHP, Symfony, Slim and WordPress work too.

API reference

Laravel out of the box

Queries, jobs, events, cache, the HTTP client, views, requests, logs, exceptions, mail and dump(), with no code at all.

Laravel guide

Query debugging

Every query with its bindings and time, slow and duplicate (N+1) badges, switched on and off from the viewer while the app runs.

Query debugging

Mail and SMS catcher

Catch what your app sends over SMTP, a Laravel mailer, and Mailgun-, Twilio- and Vonage-style APIs, in a real inbox.

Mail and SMS

Webhook simulator

Call your app back with signed Mailgun, Twilio and Vonage events, from templates, with retries and a delivery log.

Webhooks

Logs tab

Your app's log files as colored entries, with the exception's stack, context trees, live watching and filters.

Logs

Desktop app or browser

A native app for macOS, Windows and Linux with tray, hotkey and notifications, or the viewer in a browser tab.

Desktop app

Debugging by AI agents

A debug report, a CLI and an MCP server give Claude Code, Codex, Cursor and others what Peep caught, as text.

AI agents

Safe by default

Off in production, and it never slows down or breaks your app when the viewer is closed.
