brawsr: Checkpoint, Rewind, and Fork Browser Agent Sessions
NoFlounder9565 · reddit · 2026-08-13
brawsr is a session management tool for browser automation agents (currently in public alpha) that solves the pain of restarting long tasks from scratch after a failure. It introduces three core features:
- Checkpoint: Snapshot the full live browser state, including memory, at any point mid-run.
- Rewind: If a step fails, jump back to the last checkpoint and retry instead of restarting the entire task (like re-logging in).
- Fork: Branch a single checkpoint into multiple independent parallel sessions—ideal for Best-of-N exploration or running batch evals from an identical authenticated starting point.
It is compatible with popular frameworks like Playwright, browser-use, and LangChain.
