PraxlComparison
Praxl vs rulesync
27 tools, daily releases, no team layer.
rulesync is the most mature open-source CLI in this category — 994+ GitHub stars, daily commits, the widest AI tool coverage (27 adapters), and one of the cleanest TypeScript codebases in the OSS skill-management space. If you live in the terminal and just need a single source of truth for AI tool configs, it's the strongest choice. Praxl optimizes for a different shape: visual editing, team collaboration, and a managed cloud you can also self-host.
rulesync is a TypeScript CLI maintained by Daisuke Yoshikawa with backing from GMO. It treats your project's .rulesync/ directory as the canonical source and regenerates per-tool config files (CLAUDE.md, .cursorrules, .github/copilot-instructions.md, and 24 more). It can also fetch rule sets from public GitHub repos and exposes an MCP server so Claude Code can edit rules conversationally.
Feature comparison
| Feature | Praxl | rulesync |
|---|---|---|
| AI tools supported | –9 (Claude Code, Cursor, Codex, Copilot, Windsurf, Gemini, OpenCode, OpenClaw, Claude.ai) | ✓27+ (incl. Cline, Kilo, Roo, Junie, Factory Droid, Rovodev, Antigravity, JetBrains, Warp, Replit, Zed) |
| Sync model | ✓Bidirectional cloud ↔ local (edit anywhere) | –Regenerate from project source (one-way) |
| Visual web editor | ✓Monaco editor in browser, accessible from any device | –None — terminal + your text editor |
| Team workspaces | ✓Organizations with role-based access (up to 10) | –None — relies on Git for sharing |
| AI quality review | ✓5-dimension scoring (clarity, specificity, structure, completeness, actionability) | –None |
| Marketplace | ✓ClawHub integration (13,700+ skills) | –None — fetch from any GitHub repo |
| Persistent agent | –Background CLI daemon for live sync | ✓Run on demand, no daemon |
| Token storage | –~/.praxl/token mode 0600 | ✓Env vars only — nothing persisted |
| File extension allowlist | ✓Yes — blocks executables and unknown binaries | –None — accepts any extension |
| basePath sandbox | ✓Default dot-folders only + opt-in trust-path | –Path traversal check only |
| Audit log | ✓~/.praxl/audit.log records all server actions | –Operational log only, no security trail |
| Setup | –npm install -g praxl-app + connect (or Docker self-host) | ✓npm install -g rulesync (single command) |
| Release velocity | –Versioned releases as features ship | ✓Daily commits, v7.x with constant minor bumps |
| Toolchain discipline | –TypeScript + Vitest + ESLint | ✓Effect-TS + secretlint + oxlint + cspell + strict-dependencies |
| Shell execution surface | –Minimal (one spawn for browser open) | ✓Zero child_process calls — fully shell-free |
Why choose Praxl
- ✓Visual Monaco editor accessible from a browser — no terminal required
- ✓Bidirectional sync: edit a skill in the web app and it appears on disk; edit locally and it syncs back
- ✓AI quality review scores every skill on 5 dimensions and suggests fixes
- ✓Team organizations with role-based access (owner/admin/member/viewer)
- ✓Defense-in-depth security: extension allowlist, basePath sandbox, audit log, dual validation layers
- ✓Built-in marketplace with 13,700+ ClawHub skills, one-click install
Why choose rulesync
- •27+ AI tools supported — the widest coverage in the open-source category
- •Zero persistent agent: runs on demand, no daemon, nothing to compromise at rest
- •CLI-only architecture — even self-managed setup needs nothing more than `npm install -g rulesync` (Praxl self-host requires Docker + Postgres)
- •Most disciplined toolchain in OSS skill-management (Effect-TS + secretlint + oxlint)
- •Daily release cadence (v7.x), GMO corporate backing
- •Shell-free architecture: zero child_process calls, smaller attack surface by design
The verdict
If your top priority is the broadest AI tool coverage and you live in the terminal, rulesync is the strongest open-source choice — its 27 adapters and toolchain discipline are real advantages we don't try to match. Where Praxl wins is the layer above the CLI: a visual editor for non-terminal workflows, AI review of skill quality, team workspaces with RBAC, and a defense-in-depth security model with extension allowlists, basePath sandbox, and audit log. Many teams will benefit from running both — rulesync for tools Praxl doesn't yet adapt to, Praxl for the platform layer where teams actually collaborate.
