Best TypeScript agent infrastructure

The open-source agent infrastructure written in TypeScript, from the Agent Search Engine index — ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. Every project here is TypeScript-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by gateway (13k stars), with steel-browser and byterover-cli close behind. Rankings shift as projects gain stars and ship commits.
