Apistaq
What Apistaq is
Apistaq is an API governance control plane that builds versioning controls, rate-limit policies, SDKs, and a developer portal from an OpenAPI 3.1 specification. It tracks specification changes, flags breaking changes, and supports version-specific documentation, deprecation notices, and sunset dates. Rate limits can use token bucket, sliding window, or fixed window algorithms, with global, tag-level, or endpoint-level policies. Generated SDKs support TypeScript, Python, and Go, with publishing options for npm, PyPI, and pkg.go.dev. SDK generation is available on Builder and Platform plans. The portal can include an interactive explorer, versioned documentation, SDK links, and spec-derived changelogs. OpenAPI inputs can come from GitHub, GitLab, Bitbucket, a URL, or manual YAML or JSON upload. Apistaq says it does not proxy API traffic and is not an API gateway. The Free plan costs nothing and includes up to three APIs, 1M requests per month, and one portal; its versioning is limited to three versions per API and global rate limits. Builder costs $149 a month, and Platform costs $399 a month.
Who it suits
Apistaq is aimed at platform engineers, including those at fintech companies, B2B SaaS platforms, and developer-tool companies. It suits teams governing APIs from OpenAPI specifications rather than routing API traffic through a gateway.
