How StackPicks keeps GitHub data fresh

You don't need to do anything — this runs on autopilot.

  1. A cron job hits /api/cron/scrape-github every 24 hours at 2 AM IST.
  2. It pulls live stars, forks, language, license, and last-push for every published repo.
  3. Fresh values are written to Supabase.
  4. Repo pages auto-revalidate via Next.js ISR on the next visit.

What's coming next

  • Weekly refresh — new repos every Sunday; new MCPs same-day on major launches
  • **Instagram posts** — 5 per week on @stackpicks.dev, starting Mon Jun 8
  • Premium changelog — weekly deep-dives for ₹99 lifetime members

Frequently asked questions

How often does StackPicks refresh GitHub data?+

Daily. A cron job hits /api/cron/scrape-github every 24 hours and pulls live stars, forks, language, license, and last-push timestamps for every published repo. The numbers on each repo page are never more than a day stale. Pages auto-revalidate on the next request via Next.js ISR — no manual deploy needed for stats to update.

Which new repos were added on June 5, 2026?+

12 new picks: DuckDB and ClickHouse (analytics), All-Hands-AI/OpenHands (autonomous coding agent), modelcontextprotocol/servers (Anthropic's reference MCP servers), DeepSeek V3 (open-weights LLM), Convex backend, lobe-chat (self-hosted ChatGPT), Skyvern (LLM browser automation), ToolJet (open-source Retool), Langfuse, Helicone (LLM observability), and Qwik (resumable framework).

Which new MCP servers were added?+

8 production-ready MCPs: AWS (Bedrock, S3, Lambda, Cost Explorer), Cloudflare (Workers, R2, D1, DNS), Meta Ads (official, launched April 29), Groq (sub-100ms inference), DeepSeek, DuckDB (SQL over flat files), Langfuse (LLM traces), and ClickHouse (real-time analytics). All include install commands and auth notes on the /mcp directory.

How do I install one of the new MCPs?+

Open the MCP page at /mcp, click the server you want, and copy the install command (npx, uvx, or remote URL). Paste it into your Claude Desktop or Cursor MCP config file, restart the client, and the tools show up. Each MCP page lists which auth (API key, OAuth, none) it needs.

How can I suggest a new repo or MCP?+

Use the submit form at /submit-repo. We review submissions weekly. To qualify, the project must be open source (MIT, Apache, BSD, or AGPL), have commits in the last 60 days, have real users (not a toy project), and fit a category that exists in our taxonomy. We do not list paid-only tools, abandoned forks, or proof-of-concept demos.
