01
Built as code, not locked inside a canvas
Apps are TypeScript or Python projects with reusable components, runtime boundaries, and deployable artifacts. Teams can inspect, version, and review what ships.
Internal tool builder
Internal tools need a builder. Production needs a release system.
Relpin is an internal tool builder for teams that want real code, governed data access, and pinned releases instead of another shadow-IT surface.

Category position
Use visual builders when the workflow is simple and low risk. Use Relpin when the tool touches production data, needs approvals, or has to survive audits.
How to evaluate
02
Promotion is a governed path
DEV, TEST, and PROD are separate release states. Production promotion can require approvals, separation of duties, and the exact artifact hash that was reviewed.
03
Data stays server-side
Internal tools can query governed data through server-side SQL and least-privilege runtime roles instead of exposing credentials in browser-side automations.
Evaluation checklist
- Dedicated data boundary per organization
- Pinned release artifact before production
- Approval gate for sensitive environments
- Audit trail for data changes and promotion decisions
- Escape hatch to real code when the tool grows

FAQ
Frequently asked questions.
Is Relpin an internal tool builder?
Yes. Relpin builds internal tools, but it is code-first and governance-first. The goal is not just to draw screens; it is to ship reviewed tools on governed data.
When is Relpin a better fit than a visual builder?
Relpin is a better fit when the app needs production data access, controlled promotion, auditability, or long-term maintainability by engineering and platform teams.
