BetterWright

One persistent browser for AI agents with compressed snapshots, diffs, proof screenshots, TypeScript SDK, and MCP server.

BetterWright is a persistent browser runtime built specifically for AI agents, enabling them to interact with the web without managing browser sessions directly. Instead of dumping entire pages into the context window, BetterWright returns compressed accessibility tree snapshots sized for LLM context limits, with diff mode that surfaces only what changed between steps. Agents issue snippets of Playwright code; BetterWright drives the session and returns structured result envelopes. Proof screenshots serve as verifiable artifacts rather than raw pixel dumps. A TypeScript SDK, MCP server, and CLI exec command offer multiple integration paths, all sharing one persistent session underneath.
