ALMOST

A weekend of work, and real gaps remain.

Builds internal tools by dragging components onto a canvas and binding them to queries against your own databases and APIs, with permissions and audit logs around them.

Promptfree, for everyone, and the only version there is
Build me an internal admin panel generator, driven by a config file rather than a canvas.

STACK
- Astro with a Node adapter, server-rendered, no client framework
- Read-only replica of the production database wherever possible

THE CONFIG
- One YAML file per screen: a named query, the columns to show, and the actions available
- Queries are named SQL files with typed parameters, checked into the repository — never SQL from the browser
- The README must state that arbitrary query execution is deliberately impossible

SCREENS
- Table with server-side pagination, sorting and filtering by declared columns only
- A detail view per row, and forms generated from the declared writable fields

ACTIONS, WHICH IS WHERE DAMAGE HAPPENS
- Every action declares: the SQL it runs, the role that may run it, and whether it is reversible
- Irreversible actions require a typed confirmation of the record's name, not an OK button
- Every action logged append-only: who, when, which row, which parameters, and the result

PERMISSIONS
- Roles in the config; a screen and an action each name the roles allowed
- Authentication delegated to your existing single sign-on, never a second password

SAFETY
- A statement timeout on every query, and a row cap on every table view
- Writes go to the primary, reads to the replica, and the config says which is which

Include a README on adding a screen, the audit log format, and the review process for a new action.

What you lose

  • A drag-and-drop editor that reaches a working admin screen in minutes
  • Connectors to every database and API, with credentials held outside your codebase
  • Permissions and audit logs on who ran which query against production
  • Version history and staging environments for internal tools
  • The ability to hand an internal tool to a colleague who is not a developer

If you would rather not build

  • Forest Admin — paid, generated admin panels over an existing database

Why this verdict

our own opinion · changed only by a person

52/100

Verdict kinda at 52: a config-driven admin panel is a strong weekend and is safer than a canvas, because arbitrary queries are impossible by construction. The trade is who can build a screen — with Retool it is anybody, and here it is whoever can open a pull request.
