API Dash is a beautiful AI-powered open-source cross-platform API client built with Flutter, available on Desktop (macOS, Windows, Linux) and Mobile. It provides HTTP and GraphQL request creation, response visualization, folder and collection organization, code generation for multiple languages, and support for 40+ MIME types including image, audio, and PDF preview. Developed by the foss42 organization, API Dash is a lightweight alternative to Postman and Insomnia with an active open source community.
API Dash publishes 2 APIs on the APIs.io network, including API Dash, and 1 more. Tagged areas include API Client, Open-Source, Flutter, Desktop, and Mobile.
API Dash’s developer surface includes authentication, documentation, support, changelog, sandbox, API reference, getting-started guide, and 30 more developer resources.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it
carries 10 points of the composite. It is scored from the published contracts
themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already
holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in
front of it, and the first time that check is skipped a duplicate record is created.
Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet,
not penalised by it.
The six quality facets above are damped to 80 points between them,
because the conditional facet above carries the other
20. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 80% 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/api-dash: open an issue to ask a question, or submit a pull request to add artifacts.
