DevShelf is an open-source, community-driven directory indexing 565+ verified developer tools, free public APIs, AI coding agents, and Model Context Protocol (MCP) servers with zero paywalls.
Unlike static awesome-lists that accumulate broken links, DevShelf uses continuous GitHub Actions automated CI telemetry to ping documentation endpoints, verify SSL certificates, and check API uptime.
AI coding agents (such as Claude Desktop, Cursor, and Windsurf) can query DevShelf via:
- MCP Server: Run
npx devshelf mcpto expose DevShelf search tools natively over Model Context Protocol. - REST API: Make HTTP GET requests to
https://devshelf.ritualdev.in/api/v1/tools.json.
DevShelf isn't a static markdown list. It runs directly inside your terminal, in your web browser, and as a native tool inside your AI assistant:

Most developer resource lists (public-apis, free-for-dev) suffer from link rot, abandoned projects, and sneaky "free 14-day trials". DevShelf solves this with 3 unfair advantages:
| Dimension | 🧟 Static Awesome Lists & Repos | 🚀 DevShelf |
|---|---|---|
| Endpoint Health | 40%+ broken links & dead APIs sitting for years | 🛡️ Automated CI Health Checks ping every endpoint continuously |
| Trial-Bait Protection | Riddled with "14-day trials" & bait-and-switch pricing | 🚫 Strict Zero-Paywall Audit — 100% free forever tiers or MIT/Apache FOSS |
| Developer Access | Read-only markdown tables; constant browser tab flipping | ⚡ Zero-Install CLI (npx devshelf) & fuzzy TUI right in your terminal |
| AI Agent Native | None (manual copying and pasting into chat) | 🤖 Official MCP Server (npx -y @ritualdev-lab/devshelf mcp) for Claude, Cursor, & Zed |
| Data Programmability | Static markdown formatting | 📡 Free CORS JSON REST API (/api/v1/tools.json) with no keys needed |
| Creator Backing | Submissions sit unreviewed for months with zero recognition | 📢 Social Amplification Guarantee — merged tools get featured on X & LinkedIn |
DevShelf does not rely on subjective claims or stale markdown lists. Catalog integrity is grounded in three separate, automated verification tiers and an explicit sponsor transparency policy:
-
🌐 Reachable Web Endpoint (
lastCheckedAt)- Automated HTTP probe and DNS resolution tests tracking 200 OK and canonical 301/308 redirects.
- Resilient against Cloudflare / Vercel anti-bot challenge false-positives.
- Enforces an automated 14-day grace period before any broken URL enters sunset delisting.
-
🔌 Working API & Service Health (
lastVerifiedAt)- Automated endpoint connectivity and payload validation for public APIs and developer services.
- Ensures mock APIs, inference endpoints, and tool APIs return parseable data matching their schemas.
-
💳 Verified Zero-Paywall & Pricing Policy (
pricingVerifiedAt)- Automated regex and human audit heuristic scans for trial-bait detection.
- Enforces permanent free access: mandatory upfront credit cards or expiring 14-day trial traps are rejected.
-
🎖️ Sponsor & Partner Independence Disclosure
- Editorial Independence: Sponsored partner tools, directory spotlight slots, and patron badges are strictly labeled with
[Sponsored]or[Patron Backed]tags. - Sponsoring does not bypass audits: Sponsored tools must meet the exact same reachability and zero-paywall criteria as organic entries.
- Organic search rankings, categorization, and recommendation algorithms remain 100% unbiased.
- Editorial Independence: Sponsored partner tools, directory spotlight slots, and patron badges are strictly labeled with
Turn your AI coding assistant into a free developer tool & API search engine! DevShelf implements the official Model Context Protocol (MCP) over stdio:

# Or run stdio server directly for Cursor, Claude Desktop, Windsurf, or Zed
npx -y @ritualdev-lab/devshelf mcp{
"mcpServers": {
"devshelf": {
"command": "npx",
"args": ["-y", "@ritualdev-lab/devshelf", "mcp"]
}
}
