Inferrail
Try Inferrail free.No account. Personal gateway in seconds.
A hosted, isolated trial instance — demo receipts immediately, your own OpenAI or Anthropic key if you want a real one. Prefer to keep everything on your own machine instead? Self-host it — same receipt schema, zero trust required in any hosted process.
One click. Demo mode needs no key at all.
Either it hasn't been deployed yet, or this instance is temporarily unavailable.
Nothing is broken on your end — self-host Inferrail instead (pip install inferrail && inferrail serve --quickstart), or try again shortly.
Your personal gateway
Your personal base_url — point any OpenAI- or Anthropic-compatible client at it.
Your dashboard link — reopens this trial in any tab or device
Keep this link private: anyone who has it can use this trial — including any key you add, up to this trial's daily cap — until it expires.
Send a test request
Zero-key demo mode always works. Add a real key below to test with your own account instead.
Optional: say which job a request belongs to. That's how Inferrail answers "what did this piece of work cost?" — see the section further down.
Optional: add your own key
Held in this server's memory only for the life of this trial (at most 4 hours from when you add it) — never written to disk, never logged, never included in any receipt. Skip this entirely and stay in demo mode if you'd rather not.

Every receipt this trial has produced — payload-free: counts, cost, and whatever attribution you attached, never a prompt or response.
Budget burn
What does this work cost?
Every request tagged with the same Work adds up to one unit of work. Mark how it turned out, and you get cost per successful outcome — not just a token bill.
| Work | Requests | Known cost | Outcome |

Keep your data
This trial and everything in it are deleted when the countdown ends. Download a copy first if you want one — receipts, work, and task totals as JSON (never prompts or replies; those are never stored).
Want it to keep running? Run the same gateway on your own machine — free and open source, and your data never leaves it:
pip install inferrail && inferrail serve --quickstartHosted accounts that keep a trial past its expiry aren't available yet.
Report an issue
Something broken, confusing, or worth telling us? This goes privately to the team — it's never posted publicly, and no account is needed.
