Best JanitorAI Proxies in 2026: Compare Composite, OpenRouter & More
Disclosure: Composite runs this site, so it is one of the providers compared here.
Searching for the best JanitorAI proxy usually means you want more choice than a single model or provider gives you. Compare whether the service gives JanitorAI a compatible endpoint, the models you want, clear costs, and enough room for an ongoing story.
Composite is a roleplay-oriented option for users who want an OpenAI-compatible JanitorAI connection plus model choice, long-context handling, prompts, lorebooks, and workflow plugins behind the key. JanitorAI stays as the frontend, so there is no separate chat interface to learn.
What makes a good JanitorAI proxy?
A proxy is the middle layer between JanitorAI and an AI model provider. In practice, it should accept the request format JanitorAI sends and return a response JanitorAI can display. Compatibility is only the first filter. A good choice should also be transparent about billing and model access, protect your API key, and give you a way to change models when one does not suit a character.
- OpenAI-compatible API support. JanitorAI needs a provider that can accept its custom OpenAI-style connection.
- Models suited to roleplay. Character voice, instruction following, and context capacity matter more than benchmark scores alone.
- Clear spend controls. Long chats add up. Pick a provider with understandable pricing and controls you can set before a session.
- Long-story tools. Lorebooks, reusable prompts, and context management help a campaign stay readable after the opening scene.
- Model and connection status. You should be able to see models and connection health rather than guess whether a failure is your setup.
Composite vs. NanoGPT, OpenRouter, LiteRouter, and VoidAI
These are all relevant JanitorAI alternatives because each publishes an OpenAI-compatible API path. They are not interchangeable, though. Compare the model you plan to use, its context window, the billing rules, and whether the service gives you the roleplay controls you want outside JanitorAI.
| Provider | Published focus | Best reason to evaluate it |
|---|---|---|
| Composite | Roleplay configuration around the key, including prompts, lorebooks, workflow plugins, and context-management choices. | You want a reusable story setup that stays attached to the connection instead of rebuilding it per chat. |
| NanoGPT | A multi-model service with an API that documents basic OpenAI compatibility. | You want another catalogue to test against the same JanitorAI character and prompt. |
| OpenRouter | A large model marketplace that publishes model metadata and compatible parameters. | You want extensive model filtering and are happy to keep your roleplay setup in JanitorAI. |
| LiteRouter | An OpenAI-compatible proxy that advertises multi-provider routing, fallback, and context summarization. | You value routing and fallback behavior, and will test it carefully with your preferred formatting. |
| VoidAI | A unified OpenAI-compatible gateway that documents text, image, audio, video, embedding, and moderation capabilities. | You want one provider to evaluate for broader creative tooling as well as chat completions. |
Run a like-for-like comparison before committing. Use the same character definition, first message, model if available, and generation settings, then read several turns.
Why Composite is a strong JanitorAI proxy
Composite is built around AI roleplay, not a generic chat box. You can create an API key, choose from available models, and attach prompts, lorebooks, or plugins to that key. Those assets are prepared with each request, which keeps the same setup available across the chats that use it. You can run it on your own provider key at no charge from Composite, start on Synth, its free model, or add credits or a plan for the router and the full catalog.
Choose a model for the writing you enjoy. A larger context window does not automatically improve character voice, and a cheaper model can make more sense for experimental chats. Test with the same character card and opening prompt before moving an established story.
How to connect Composite to JanitorAI
- Create a Composite account and make an API key. To use the free models without credits or a plan, link Discord on your account page.
- In JanitorAI, open the API or proxy settings and choose its custom OpenAI-compatible provider option.
- Set the base URL to
https://composite.lucidity.sh/v1/chat/completions. - Paste your Composite API key and select an allowed Composite model.
- Send a short test message before starting a longer chat.
JanitorAI's settings can move as the product changes, so treat labels in the interface as the source of truth. The values above are also kept up to date on the JanitorAI proxy guide, including troubleshooting for connection errors and rate limits. Never paste your API key into a public character description or share it in screenshots.
Free models to try on JanitorAI
As of October 21, 2026, these models are on Composite's free list. Each guide gives the free model ID, the JanitorAI proxy settings, and what the model is good at:
- Synth 2.5 Flash, Composite's free creative model, with its own daily count
- GLM 5.3 Flash, Z.ai's multimodal model that always reasons
- DeepSeek V4.1 Flash, with optional reasoning and image input
- DeepSeek V4 Flash 0731, a text-only DeepSeek revision
Apart from Synth, the free models share 80 requests a day per account. The list changes, so check the free models on the Models page for the current set.
Common JanitorAI proxy problems
If the connection fails, check the endpoint first. JanitorAI needs the full chat-completions URL above, while other clients often use only a base URL. Then confirm that the API key is active and that the selected model is allowed by the key. A model response that feels off is a different problem: change the model, inspect the character card, and reduce conflicting instructions before assuming the proxy is broken.
The bottom line
Choose a JanitorAI proxy whose prices and limits you can inspect, then test the connection before a long session. Composite fits users who want an OpenAI-compatible connection, roleplay-specific memory and worldbuilding tools, and the option to move between models. Create a key, run a test scene, and keep the setup that gives your characters the voice you want.
