nablr
AI-powered SDLC governance via Model Context Protocol.
nablr (pronounced like "enabler") connects to your AI assistant (Cursor, Claude Desktop, Windsurf) and enforces quality gates across your entire software delivery lifecycle — 18 expert personas, 12 built-in scanners, full workflow orchestration.
Documentation: docs.nablr.dev
Why nablr
AI assistants accelerate typing, not engineering.
| What they promised | What actually happens |
|---|---|
| Ship faster | More code, same bugs |
| Higher quality | AI-generated tech debt |
| Reduce costs | Increased rework cycles |
nablr is the orchestration layer that fixes this: quality enforcement, workflow context, and persistent state injected directly into your AI assistant via MCP.

Security
nablr makes exactly one category of outbound call: license validation to nablr-api.nablrco.workers.dev:443. Your code never leaves your machine.
Paid assets are pre-cached to ~/.nablr_cache/assets/ on activation — all subsequent prompt generation works fully offline.
# Verify no unexpected network calls
uv run python scripts/airgap_proof.py
