What is act101?
act101 empowers engineers to refactor and port code across 163 languages with precision. It’s designed for individual developers and teams who want to ensure their AI coding agents produce reliable, tested changes without guesswork. By analyzing code, executing refactors, and providing deterministic merge verdicts, act101 transforms the coding process into a structured and verifiable workflow.
The platform operates in three stages: Analyze, Act, and Attest. First, it analyzes the codebase with 41 analyzers to identify potential issues. Then, it applies one of 183 refactor operations, ensuring changes are made efficiently. Finally, it attests to the changes with a clear verdict and rollback options, allowing developers to maintain control over their code quality. With act101, you can trust that every modification is backed by thorough analysis and testing.
Best for: Individual engineers and codebase owners seeking reliable AI refactoring.

What is Relpin?
Relpin is a platform for internal tools. Apps are real TypeScript/React or Python code. You edit them in the browser, next to a code editor, an AI assistant, live preview, a terminal, Python workflows on a canvas, and a Postgres database scoped to your organisation.
Releases are content-addressed. Every publish is canonicalized, SHA-256 hashed and pinned to exact schema versions, so the build you tested is the build that ships.
Promotion runs DEV to TEST to PROD behind approval gates. TEST needs one approval. PROD needs two, and whoever requested the release cannot approve it. Promotion fails closed if the schema has drifted since the plan.
Each organisation gets its own Postgres database with row-level audit, not a shared one. Mutations, releases and deployments are recorded with the actor and the before/after values.
Most app builders stop once the UI is generated. The part they skip is production data access with no environment separation, no approvals and no audit trail. That is the part Relpin covers.
Open beta. Free plan, paid from EUR 29 per month. Runs in the browser, nothing to install.
Best for: Engineering, ops and platform teams that build internal tools against production data. Most useful where audits, compliance or access control already matter.
