Appsmith

Appsmith is an open source (Apache-2.0) low-code platform for building internal tools, admin panels and workflow applications on top of 25+ databases and any REST or GraphQL API. It runs self-hosted via Docker, Kubernetes or Helm, or as Appsmith Cloud. Its agent surface is a first-party Model Context Protocol server bundled into the Appsmith image and fronted at /mcp, exposing 61 tools that build and edit applications under the calling user's own permissions; it ships disabled by default and requires a per-user mcp_ token. Appsmith publishes no public REST API reference: the platform API at /api/v1 is undocumented editor traffic and its springdoc OpenAPI surface is disabled by default and authenticated when enabled.

Appsmith publishes 3 APIs on the APIs.io network: Applications API, Datasources API, and Workspaces API. Tagged areas include Low-Code, Open-Source, Internal Tools, Workflow-Automation, and Developer Tools.

The Appsmith catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Appsmith’s developer surface includes authentication, documentation, changelog, CLI, getting-started guide, support, engineering blog, and 33 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/appsmith: open an issue to ask a question, or submit a pull request to add artifacts.
