free-for.dev

free-for.dev lists software and hosted services with free developer tiers, scoped to what the maintainers consider useful for infrastructure developers, system administrators and DevOps practitioners rather than every free offering on the internet. Entries are organized under headings including cloud providers' always-free limits, analytics, APIs and ML, artifact repositories, CI and CD, CMS, code quality, log management, monitoring, source code hosting and authentication.

To be listed, a service must offer an ongoing free tier rather than a time-limited trial, and if the tier is time-bucketed it must last at least a year; the list also screens for security basics such as not restricting TLS to paid plans. Entries come from pull requests reviewed by the maintainers, and the list is explicitly opinionated about what counts as in scope.
