Created within the last 120 days — the newest entrants to the ecosystem.
The agent-payments ecosystem is young enough that a project launched four months ago can already be infrastructure. This collection tracks the newest entrants — repositories created within the last 120 days.
New here does not mean unproven: several of these have hundreds of stars already. But evaluate them with the usual care for young codebases, and check the production-ready collection when the stakes are high.
Selection criteria: repository created within the last 120 days, sorted newest first.

Every project in this collection meets these criteria: repository created within the last 120 days, sorted newest first. The list is computed from our live crawl of 1.5k+ open-source repositories — it is not hand-picked or pay-to-list.
The underlying data (stars, activity, new repositories) is refreshed by our crawler on a weekly cycle, so collections re-compute with each deployment.
