What Users Say About Impeccable

👍 What Users Love

✓Solves a real and specific problem — 'AI-generated UI looks like AI' — with a deterministic detector (46 rules, no LLM, no API key), so it costs nothing to run and produces reproducible results in CI.
✓One-command install across the entire mainstream agent stack (Claude Code, Cursor, Copilot, Gemini CLI, Codex CLI, Windsurf, and more) is unusually well-executed — most 'agent skills' work on one provider only.
✓Apache 2.0 with 45k+ GitHub stars and a credible author (Paul Bakaus, jQuery UI) — free forever with real community traction and no vendor-lock risk.

👎 Common Concerns

⚠It's opinionated by design — teams with an established design system may find some rules (e.g. gray-on-colored contrast, gradient bans) conflict with their brand and need muting.
⚠The deterministic rules catch surface issues but can't judge taste, layout hierarchy, or brand fit — you still need designers or the LLM commands for the harder call.
⚠No MCP support: integration is via provider-specific skill installers and hooks, so if you're on a provider that isn't yet supported (or a custom agent framework), you'll wrap the CLI yourself.
