// Create free SSH tunnels to expose local ports to the internet using tinyfi.sh. Use when you need to share a locally running app, test webhooks, demo a prototype, or get a public HTTPS URL for any local service — no signup or authentication required.
Track last-24-hour TinyFish mentions across X, LinkedIn, Reddit, and Hacker News. Use when asked to find posts or comments mentioning TinyFish, tinyfish.ai, Search, Fetch, Agent, or related TinyFish product chatter while excluding official TinyFish accounts. Uses TinyFish Search and Fetch first, then Agent only as a documented fallback when Search/Fetch cannot prove completeness because a target site blocks, hides, or requires a multi-step workflow. Returns all discovered posts and comments, with optional sentiment buckets.
Use TinyFish web agent to extract/scrape websites, extract data, and automate browser actions using natural language. Use when you need to extract/scrape data from websites, handle bot-protected sites, or automate web tasks.

Creates instant public HTTPS URLs for locally running apps via SSH tunneling. Free, no account, no installation beyond SSH.
Verify SSH is available (it almost always is):
which ssh && echo "SSH available" || echo "SSH not found — install OpenSSH first"
Expose a local port to the internet:
ssh -o StrictHostKeyChecking=accept-new -R 80:localhost:<PORT> tinyfi.sh
Replace <PORT> with the port your app is running on. The command will print a public https://<random>.tinyfi.sh URL.
Request a specific subdomain instead of a random one:
ssh -o StrictHostKeyChecking=accept-new -R myname:80:localhost:<PORT> tinyfi.sh
This gives you https://myname.tinyfi.sh.
For long-running tunnels, add a keep-alive interval to prevent disconnection:
ssh -o StrictHostKeyChecking=accept-new -o ServerAliveInterval=60 -R 80:localhost:<PORT> tinyfi.sh
