Apistaq
What it is
Apistaq is an API governance control plane for platform teams that derives versioning, rate-limit policies, SDKs, and developer portals from OpenAPI specifications. It tracks spec changes, identifies breaking changes, and supports per-version documentation, deprecation notices, and sunset dates. Rate limits can use token bucket, sliding window, or fixed window algorithms, with policies inherited globally or at tag and endpoint levels. Apistaq generates TypeScript, Python, and Go SDKs that can be published to npm, PyPI, and pkg.go.dev; SDK generation is available on Builder and Platform plans. Its generated portal can include an interactive explorer, versioned documentation, SDK links, and spec-derived changelogs. Specs can be provided through GitHub, GitLab, Bitbucket, a direct URL, or manual YAML or JSON upload. Apistaq says it does not proxy API traffic and is not an API gateway. The Free plan is $0 per month and includes up to three APIs, 1M requests per month, and one portal, with basic versioning for up to three versions per API and global rate limits. Builder costs $149 per month; Platform costs $399 per month.
For and against
For
- Tracks spec changes and detects breaking changes.
- Supports three rate-limit algorithms.
- Generates TypeScript, Python, and Go SDKs.
- Accepts specs from repositories, URLs, or uploads.
- Free plan includes up to three APIs.
Against
- Free plan versioning is limited to three versions per API.
- Free plan includes global rate limits only.
- SDK generation is limited to Builder and Platform.
The verdict
Apistaq derives API governance tools and a developer portal from OpenAPI specs, without proxying API traffic. Its free tier provides a defined starting scope, while SDK generation requires a paid plan.
Who it suits
It is aimed at platform engineers, including those at fintech companies, B2B SaaS platforms, and developer-tool companies. Teams that need SDK generation should consider Builder or Platform, since it is not included in the Free plan.
