About ProofMark Studio
ProofMark Studio is a working hub for proofing, converting, signing, and transforming PDFs. It composes independent sibling apps behind a single catalog UI, so every tool keeps its own repo, test suite, and release cadence while the hub stays thin.
What ships today
- A React catalog of 49 tool tiles across Organize, Convert, Edit, Sign, Proof, AI, and Workflow groups.
- Per-tile feature flags (
TOOL_<SLUG>_ENABLED=false) that demote a live tile to a paused stub in under a minute — no redeploy required. - A structured
/api/toolscontract that the React catalog reads at runtime, so the UI can never drift from the registry.
Philosophy
- Composition over monolith. ProofMark PDF, Text Inspection, and future siblings are independent FastAPI processes; the hub routes and redirects, nothing more.
- Small verifiable steps. Every phase has a failing test first, a promotion commit, and a tag when the exit gate is met.
- Observability over cleverness. Every decision point logs
[tag] messageso silent failures have nowhere to hide.
