How we match

Choose the kind of thing you made and the features you need. The results respond to the capabilities recorded in our directory.

Each result explains its fit or mismatch. Unverified commercial-use permission is marked for a terms check. Unknown free features don’t count as confirmed fits.

Apps can run in the browser, as serverless functions, or on a persistent server. For apps, choose a runtime. For AI agents, choose an agent service, MCP server, or code sandbox. For sites and files, choose web pages or file links. A sandbox or serverless endpoint is not a continuously running process. In each group, select several to see hosts that support any selected option. Leave them blank to explore broadly; your agent can check the runtime before publishing. Docs & media candidates also need an exact file-format and size check. Commercial mode removes records with documented personal or non-production restrictions; it does not certify permission on other hosts.

Open a host to read its limits and sources. The agent brief packages your choices and those limits into instructions you can paste into your agent. It does not publish anything.

Each record has its own review date (October 11–November 14, 2026); deployments, privacy, support, and uptime have not been tested. There are no paid placements or affiliate links in this edition.
