03API, SDKs and integration
Appsmith connects to databases, SaaS tools, LLMs, and REST or GraphQL APIs. Developers assemble interfaces with drag-and-drop widgets, then customize behavior and data handling with JavaScript. The platform also supports HTML, CSS and external libraries, and can generate widget or workflow code from natural-language prompts. Its Git workflow supports repository syncing, branches, reviews and deployment through CI/CD.
Retool connects apps directly to production data sources using existing permissions. Its builder accepts natural-language prompts, and teams can import React apps by uploading a ZIP or syncing with GitHub. Retool also describes building with its MCP server or CLI and deploying into a governed environment. The homepages do not specify SDK names or a public platform API contract, so confirm those requirements with the vendors. Retool links to a full integrations list but does not give a count; Appsmith names its supported connection categories.
04Open source, self-hosting and lock-in
Appsmith describes itself as open source and says any edition can run in your infrastructure, including air-gapped deployments. The licence name is not published on its homepage, so verify licence terms before embedding or redistributing it. Its Git-based workflows provide a route for managing app changes in repositories and deploying merged updates.
Retool supports cloud, self-hosted and air-gapped deployments on Enterprise. Its homepage does not identify an open-source licence. Neither homepage describes a full data-export or migration path, so ask what can be exported, in which formats, and whether app definitions, workflows and permissions move with the data. Both products connect to production systems, but their builders and deployment workflows differ; plan for migration work if your app logic becomes specific to either platform.
