OpenCola

OpenCola is a non-profit organization building free, open-source, local-first software as an alternative to corporate social media and cloud platforms. Its application keeps a user's data on their own device by default, offering personal search, offline content archives, multiple personas, trust-based connections via tokens, information-centric collaboration, and community moderation. The project is grounded in four principles: transparency, accountability, personal control, and security (cryptographic verification). It is a revival of the original OpenCola (1999), and the current release is a local desktop application rather than a hosted service. OpenCola publishes no public web API, developer portal, SDK, or OpenAPI at this time; this profile captures its identity and open-source posture for the API Evangelist network.

OpenCola is profiled on the APIs.io network. Tagged areas include Company, Open Source, Decentralization, Local-First, and Personal Data.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/opencola: open an issue to ask a question, or submit a pull request to add artifacts.
