Appsmith

Appsmith builds internal dashboards fast: connect a data source, drop in prebuilt widgets, and let your ops team read and update records through a drag-and-drop UI. It talks to basically anything, Postgres, MySQL, MongoDB, REST, GraphQL, Google Sheets, so it's the glue for the admin panels nobody wants to hand-build.

The self-hosted Community Edition is the real product, not a crippled teaser: unlimited apps, unlimited users, Git version control, all the core widgets. It moved to a 2.x line in 2026, with an Ask AI assistant for building and debugging, and that upgrade is a breaking operational step. Installs older than v1.99 have to hop to 1.99 first, then to 2.0+, and the bundled MongoDB, Java, and Node versions all jumped. Budget time for the migration if you self-host.

Solo and small teams: self-host Community, it's free and capable. Teams that need SSO, audit logs, and granular roles: the cloud or self-hosted Business Edition runs $15/user/mo (a team of 10 is $150/mo). Large orgs with compliance needs: Enterprise starts at $2,500/mo for 100 users with SAML/OIDC and managed hosting. Compare against Budibase and ToolJet before you commit; they're close.

The catch: once internal tools get complex, the drag-and-drop hits a ceiling and custom logic means writing JavaScript inside their framework, which is more painful to debug than just writing code. If your team has real developers, you may outgrow it.
