Libretto turns browser flows into APIs
Libretto is an open-source toolkit and CLI for coding agents that combines a live browser, session recording, and network capture so agents can inspect pages, replay actions, debug workflows, and reverse-engineer hidden site APIs into more reliable automations.
// ANALYSIS
Hot take: this is less “browser automation” and more “browser-to-API extraction for agents,” which is the right abstraction when UI selectors are brittle and the real work is already happening behind the page.
- –It attacks a real failure mode in agent workflows: DOM-driven automation breaks often, while internal endpoints are usually more stable.
- –The network-capture angle makes it more useful than a generic browser runner because it can convert manual flows into direct request scripts.
- –The repo positions it as a practical tool for maintaining integrations, especially in systems like healthcare portals where APIs are missing or inaccessible.
- –The biggest upside is token efficiency: the agent can inspect and reason over compact snapshots instead of dumping full browser state every step.
