Janitor AI Free Proxy & API Key Guide (2026): OpenRouter, Gemini, DeepSeek & Claude Setup

If you’ve searched for a Janitor AI free proxy, you’ve probably hit two kinds of pages that don’t actually help. One tries to sell you a residential IP service meant for web scraping. The other tells you to “just paste an API key” without explaining which one, where, or what breaks. Both leave you staring at a connection error.

Here’s the honest version. In Janitor AI, a “proxy” almost always means a link to a real language model — OpenRouter, Google’s Gemini, DeepSeek, or Claude — not an IP address. This guide walks through each setup with the exact URLs, an honest free-vs-paid breakdown, and the safety stuff most guides skip. No hype, no risky hacks.

What a Proxy or API Key Actually Does in Janitor AI

API proxy vs network proxy — which one you need. This is the confusion that wastes the most time. A network (IP) proxy hides your location — it’s for scraping and geo-unblocking, and it has nothing to do with which AI model answers your character. A few sites that rank for “Janitor AI proxy” are actually selling this, which is why their advice never connects.

What you want is an LLM / API proxy: a service that takes your chat and routes it to a smarter model. When this guide says “proxy,” that’s what it means.

How the request actually flows. Janitor AI has its own built-in model (JanitorLLM). When you add a custom proxy, the path changes: Janitor sends your message → the proxy or provider receives it in the standard OpenAI chat format → the model generates a reply → it travels back to your chat. That OpenAI-format detail matters later, especially for Gemini. Keep it in mind.

You only need three things:

Get those three right and almost everything works. Get one wrong — a stray space, a missing :free, the wrong URL — and you get an error. That’s genuinely 90% of setup failures.

How to Use OpenRouter on Janitor AI (Without Errors)

OpenRouter is the most reliable starting point, and it has a genuine free tier. It routes to dozens of models through one key, so it’s the easiest way to test before paying anything.

Get your OpenRouter key.

1. Sign up free at openrouter.ai with Google or email.
2. Click your profile icon → Keys → Create Key.
3. Name it (e.g. “Janitor”) and copy it somewhere safe — it’s shown once.

The exact configuration. In Janitor AI, open any chat → menu (☰) → API Settings → Proxy → + Add Configuration. Then fill in:

Save, then refresh the page. That refresh is not optional — skip it and you’ll see an error on your first message. The :free at the end of a model name is what makes it free; the same model without :free charges credits.

The $10 move: 50 → 1,000 free messages a day. On a fresh account, free models are capped at 50 requests per day. Add $10 in credits once, and that daily cap jumps to 1,000 requests/day on free models — and the credits never expire. This isn’t a loophole; it’s OpenRouter’s published policy.

For light, casual chats the free 50/day is fine. If you roleplay daily and keep hitting the wall, the one-time $10 is the single best value here — you keep using free models, just 20x more of them. One catch: failed requests still count toward your quota, and the per-minute limit (around 20/min) stays the same either way.

When a free model suddenly stops working. Free models get rotated out or overloaded constantly. If yours dies, switch, don’t quit. On OpenRouter, search “free” in the model list to see what’s currently live, and keep two or three known-good slugs as backups. Building that habit matters more than memorizing any single model name, because the names change.

Gemini on Janitor AI — Google AI Studio Direct Setup

Google’s Gemini has a generous free tier, which makes it tempting. But it needs slightly different handling than OpenRouter.

Why Gemini needs special treatment. Remember the OpenAI-format detail from earlier? Gemini’s native API doesn’t speak that format by default. Google does offer an OpenAI-compatibility endpoint, which is the bridge that lets Janitor talk to Gemini at all.

Get your Google AI Studio key.

1. Go to aistudio.google.com and sign in with Google.
2. Click Get API key → Create API key.
3. Copy and save it.

Two ways to connect it:

Two honest notes. First, Google rotates model names — confirm the current free Flash slug in AI Studio rather than copying an old one. Second, the direct path can be finicky inside Janitor’s proxy field; if it won’t connect, the OpenRouter route is the dependable fallback.

Free-tier limits and blank replies. Gemini’s free tier has daily and per-minute request caps that Google adjusts often, so treat any specific number as temporary. If your character just shows “replying” and nothing arrives, it’s usually one of three things: you hit the free rate limit (wait a bit), the model name or URL is slightly off, or your key needs regenerating. Work through those in order before assuming it’s broken.

DeepSeek on Janitor AI — Free vs Cheap-Paid

DeepSeek is the value pick. It’s a strong roleplay model and one of the cheapest serious APIs available.

The free DeepSeek routes. You’ve got two no-cost options: use DeepSeek’s :free slugs through OpenRouter, or use a serverless provider that offers a free DeepSeek tier. Those serverless free tiers change their limits regularly, so check the provider’s current free allowance before relying on it — and see our [DeepSeek setup guide] for the full walkthrough.

Direct DeepSeek API — and why it’s so cheap. Going direct uses Proxy URL https://api.deepseek.com/v1/chat/completions with model deepseek-chat (faster) or deepseek-reasoner (deeper reasoning). New accounts also get roughly 5 million free tokens to start.

On pricing, DeepSeek’s flagship Flash tier runs around $0.14 per million input tokens and $0.28 per million output. A typical roleplay message is a tiny fraction of a million tokens, so a few dollars of credit stretches a long way for most users. I’m giving you the rate rather than a “lasts X weeks” promise, because how long it lasts depends entirely on how much you chat.

Why direct usually beats a random free proxy. Here’s the reframe most guides miss: when an official API is this cheap and gives you free starter tokens, the appeal of pasting your data into an unknown public “free proxy” mostly disappears. You get stability, no shared rate limits, and nobody sitting in the middle of your traffic.

Can You Use Claude on Janitor AI for Free? (Honest Answer)

The reality. No — there is no legitimately free Claude. Claude is a paid model. You access it either through a paid Anthropic API key or through OpenRouter credits, and Claude models on OpenRouter are paid passthrough (they never carry a :free tag). Anyone promising “free Claude” is almost always pointing you at something sketchy.

How to set up Claude the right way. If you want Claude’s quality — and it’s excellent for long, consistent roleplay — the clean route is OpenRouter with credits added. Add a configuration with the OpenRouter Proxy URL and a Claude model slug (no :free), and your credits get charged per use. Paid, stable, and safe.

Why “free Claude pool” links are a trap. These usually run on borrowed or pooled credentials and route your messages through a server you don’t control. Best case it’s unreliable and dies overnight. Worst case it logs your prompts — or harvests any paid key you paste in. Not worth it.

Best Custom Proxy URLs for Janitor AI (2026 Quick Reference)

Bookmark this. These are the working base URLs, verified against each provider’s documentation.

Is there a truly “unlimited” free proxy? Honestly, no. Anything advertised as “unlimited, no limit, free forever” is either overloaded, short-lived, or quietly logging you. The realistic best is the highest stable free ceiling: OpenRouter’s 1,000 requests/day after a one-time $10, with a couple of free models as fallbacks. That’s as close to “no wall” as it gets without risk.

Run Your Own Proxy — The Self-Host Method

When it’s actually worth it. Self-hosting appeals to people tired of public proxies dying. To set expectations: hosting your own proxy gives you privacy and control — it does not magically create unlimited free tokens. You’re still bound by whatever provider’s limits sit behind it. What you gain is that nobody else logs your traffic.

The local options. Tools like LiteLLM or similar OpenAI-compatible clients can run on your own PC and route your own provider keys. If you’re comfortable with a terminal, this is the most private setup possible. If you’re not, it’s probably not worth the effort over OpenRouter.

Free cloud hosting. You can also host on a free cloud tier like Render. Just know the free tiers have real caveats — bandwidth caps and instances that sleep when idle, which can add a cold-start delay to your first message. Fine for personal use, not for heavy daily roleplay.

Free Proxy Safety — The Token-Stealing Reality

This is the part nobody selling you a proxy wants to discuss, and it’s the most important section here.

How a bad proxy can burn you. When you route Janitor through a public reverse proxy, every message passes through that operator’s server. A malicious one can log your conversations, and — far worse — capture any API key you paste into it. A stolen paid key can be drained or resold before you notice.

Red flags to walk away from:

• Shared as a random link in a Discord with no named source or documentation.
• Asks you to paste a paid API key into their hosted service.
• Promises “unlimited,” “uncensored,” or “no limits” as the main selling point.
• No way to see what the server does with your data.

Protecting your keys.

1. Treat every key like a password — never share a screen or clipboard with it visible.
2. If a key might be exposed, revoke and regenerate it immediately. On Anthropic, OpenRouter, and Google it takes under a minute.
3. Prefer official providers or your own self-host over unknown middlemen.

Fixing Common Janitor AI Proxy Errors (Quick)

A fast reference for the usual culprits. For the full breakdown, see our [proxy error fixes guide].

Error 429 (rate limit / overload). Too many requests — either you hit your daily/per-minute cap, or a free model is overloaded by other users. Fix: wait a few minutes, switch to a different free model, or add credits to raise your limit.

The browser refresh ritual. Janitor caches your proxy settings, so changes don’t take effect until you reload. After saving any new URL, key, or model, hard-refresh the page (or close and reopen the tab). Many “it’s not working” complaints are just a skipped refresh.

Blank reply or “failed to fetch.” Usually a network hiccup, an expired key, or a context window that’s full. Quick passes: refresh, start a new chat if the conversation is very long, regenerate the key, or try another browser.

Generation Settings for Clean Output (No Loops, No Dry Replies)

Temperature, by model type. When you switch proxies, Janitor may ask to reset your generation settings. Don’t blindly accept a one-size value — the right temperature depends on the model:

Start near the model’s default and adjust in small steps. If you’re unsure what a specific model prefers, the provider’s docs usually say.

Killing loops and dry replies. Repetitive or flat output is often a settings issue, not a “bad model.” If a character keeps reusing phrases, nudge the repetition/frequency settings up slightly and shorten an overlong chat (huge histories crowd out the model’s attention). Clear, specific character cards do more for response quality than any single setting.

Stack Your Free Tiers — A Practical Routine

Honest framing: stacking, not “infinite.” You can’t get truly unlimited free AI, but you can spread your usage across providers so you rarely hit a wall. When one free tier taps out, move to the next.

A sample routine.

1. Start on a Gemini free model for everyday chats.
2. When it rate-limits, switch to an OpenRouter free model.
3. Keep a DeepSeek config (free starter tokens, then near-free) as your third fallback.

One ToS note: rotating between different services you legitimately signed up for is fine. Creating many fake accounts on one service to dodge its limits usually violates that provider’s terms — don’t do it.

Final Take

Setting up a custom model in Janitor AI isn’t hard once you ignore the noise. Start with OpenRouter for the easiest reliable free tier, lean on DeepSeek for value, treat Gemini as a strong free option, and pay for Claude only if you want its quality — never chase a “free Claude” link. Above all, keep your keys on official rails so nobody pockets them.
