WARNING
Running the browser runner on GitHub Actions' free tier for 24/7 production workloads conflicts with GitHub's Terms of Service (Actions is for CI/CD, not servers). For always-on use, prefer a self-hosted runner on your own machine or a small paid VPS. A spare GitHub account only isolates risk for experiments — it doesn't make ToS-violating usage compliant.
Social (fxembed-worker)
| Piece | Free | Paid |
|---|---|---|
| Cloudflare Workers 🟢 | 100k req/day, no card | $5/mo → 10M req/mo |
| X/Twitter API key | Not needed — the worker runs logged-out | — |
No X API key, no signup, no tokens for normal use.
The app itself
AgentX is free and open source (github.com/gogibeta/AgentX). No account, no subscription, no ads — forever.
Docs site hosting
| Piece | Free | Paid |
|---|---|---|
