Who Rikkahub is for#

Developers comparing AI model outputs across providers

Rikkahub lets you send the same prompt to GPT-4o, Claude, and Gemini in sequence without opening three apps. Configure each provider's base URL and model list independently, making it practical to compare outputs for code generation, summarization, or classification tasks.

Skip if:

If you primarily use one provider, the official app is simpler to set up and gives access to that provider's free consumer tier. Rikkahub's value is across multiple providers; for single-provider use it adds setup overhead without benefit.

Android users running agentic workflows

The proot workspace gives the AI a real Linux environment on your phone without root. It can run scripts, process documents, and execute multi-step tasks beyond chat. MCP support extends this further by connecting the AI to external tools and servers you configure.

Skip if:

If your agent workflows require significant compute, persistent background processes, or long-running tasks, a phone-based proot environment will hit resource limits faster than a cloud agent or dedicated server.

Power users avoiding multi-model aggregator costs

Poe charges a monthly subscription to access multiple AI models through its gateway. Rikkahub routes requests directly to each provider using your own API keys, so you pay only the provider's per-token rate with no markup. Users who already hold API access to multiple providers pay nothing extra for multi-model access on Android.

Skip if:

If you rely on the providers' free consumer tiers, Rikkahub requires paid API keys regardless of usage volume. The free-tier path remains through each provider's own official app.

the problem

The problem it solves#

Android users who rely on more than one AI provider today manage a fragmented setup: the ChatGPT app for one task, Google Gemini for another, and Claude.ai for a third. Each requires its own login, interface, and billing arrangement, and switching between them breaks focus during active work.

Multi-model aggregators like Poe promise to consolidate this, but they charge a subscription on top of whatever the providers cost and route requests through their own API layer, limiting which models and features are available. A user who wants Claude's extended context, Gemini's grounding features, and GPT's code tools from one place ends up either paying double or making tradeoffs about model access.

how Rikkahub solves it

How it solves it#

Multi-Provider API Support

Connect to OpenAI, Google, Anthropic, and any OpenAI-compatible API (DeepSeek, OpenRouter, local models) by configuring a base URL and API key per provider. QR code export and import makes it fast to share provider configurations across devices without re-entering credentials.

Proot Agent Workspace

A lightweight Linux environment runs on your Android device via proot without requiring root access. The AI can read and write files, execute scripts, and handle tasks like document processing, information gathering, and code execution directly on your phone. No separate server needed.

MCP and Skills Integration

Rikkahub supports Model Context Protocol (MCP), letting you connect any MCP-compatible server for AI tool use. Skills extend the AI with predefined action sets. This combination makes multi-step tool workflows available from a mobile interface, beyond what standard chat apps offer.

File-Based Persistent Memory

Memory is stored as files on your device, giving the AI persistent context across conversations without requiring a cloud memory service. The model can recall your preferences, past tasks, and ongoing projects across sessions, similar to ChatGPT's memory feature but stored locally.

Search Enhancement

Integrates with Exa, Tavily, Zhipu, LinkUp, Brave, Perplexity, and other search providers to give the AI access to real-time information. This makes Rikkahub useful for research tasks where the model's training cutoff would otherwise return outdated results.

Strengths and trade-offs#

Strengths

Direct provider routing with no aggregator markupAPI requests go from your device directly to the provider. With Poe, you pay a monthly subscription on top of the provider's per-token costs. With Rikkahub, your bill is exactly what the provider charges per token, with no intermediary taking a cut or imposing usage limits.
Active development and 8,859 GitHub starsThe repository reached 8,859 stars and had a commit as recently as November 13, 2026, indicating active maintenance. AGPL-3.0 source code is fully auditable, which matters for users who want to verify how their API keys are stored and transmitted before trusting a third-party app with them.
Agent capabilities beyond basic chatThe proot workspace and MCP support put Rikkahub ahead of most mobile AI clients, which are chat-only. Agents can run real Linux commands, process files, and call external tools through MCP, all from the phone without requiring a separate server or cloud agent subscription.
Google Play distributionInstalling from Google Play means verified APKs and automatic updates, reducing the security risk of running unsigned binaries. No manual APK management or sideloading for most users, while the AGPL-3.0 source remains available for those who prefer to build it themselves.

Trade-offs

-Requires API keys from every providerThere is no built-in free tier or consumer account. Each provider requires its own API key, which incurs per-token costs regardless of usage volume. Users who currently use the free tiers of ChatGPT or Gemini will pay more with Rikkahub than with the official consumer apps, where basic access is free.
-Android-only native experienceThe primary app targets Android. A web interface is available for browser access, but there is no native iOS app. iOS users looking for a comparable multi-provider client on mobile have no equivalent first-party option from this project.
-No pull requests accepted; 297 open issuesThe README states the project does not accept pull requests. Bug fixes and new features depend entirely on the core maintainer. With 297 open issues as of November 2026, the backlog pace depends on a single contributor, which creates a risk if maintainer availability drops.

versus alternatives

Rikkahub vs alternatives#

Rikkahub vs Poe

Both Rikkahub and Poe give Android users access to multiple AI models from one interface. The key difference is the routing model: Poe is a proprietary subscription service that proxies requests through its own API layer, requiring a monthly subscription for full access to premium models. Rikkahub routes requests directly from your device to each provider using your own API keys, so your only cost is what each provider charges per token.

Feature	Rikkahub	Poe
License	AGPL-3.0	Proprietary
Cost	Free app; pay provider per token	Monthly subscription
Model access	Any OpenAI-compatible API	Curated provider set
Agent workspace	Yes (proot Linux)	No
MCP support	Yes	No
iOS support	No (Android and web)	Yes

Rikkahub wins when you already hold API keys and want to avoid paying an aggregator, or when you need agent capabilities Poe does not offer. Poe is worth considering when you want a managed multi-provider experience with a single subscription, no API key setup, and native iOS support.

Rikkahub vs ChatGPT Android

The ChatGPT Android app is OpenAI's official client and includes a free tier, voice mode, and image generation. Rikkahub is an open source alternative that adds multi-provider support and agent capabilities, but requires you to bring an OpenAI API key and gives up access to ChatGPT's free consumer tier.

Feature	Rikkahub	ChatGPT Android
License	AGPL-3.0	Proprietary
Providers	Any OpenAI-compatible API	OpenAI only
Free tier	None (API key required)	Yes (ChatGPT free)
Agent workspace	Yes (proot Linux)	Yes (ChatGPT tools)
MCP support	Yes	No
Memory	File-based, local	ChatGPT cloud memory

Rikkahub is the better choice when you use multiple providers and want one Android app for all of them, or when you want local control over conversation history and API keys. The ChatGPT Android app is better when you want OpenAI's free tier, voice mode, or image generation without managing API costs.

frequently asked

FAQ#

Is Rikkahub free to use?

The app itself is free on Google Play and open source under AGPL-3.0. Using AI models through it requires your own API keys from each provider, billed per token by that provider. There is no subscription fee for Rikkahub itself.

Which AI providers does Rikkahub support?

Rikkahub supports any provider with an OpenAI-compatible API, which includes OpenAI (GPT-4o, o3), Anthropic (Claude), Google (Gemini), DeepSeek, OpenRouter, and others. You configure the base URL and API key for each provider in the app settings.

What is the agent workspace and what can I do with it?

The agent workspace is a lightweight Linux environment running on your Android device via proot, requiring no root access. It gives the AI a real file system to read and write, letting it perform tasks like document processing, code execution, and data collection directly on your phone. For heavy computation or long-running background processes, it is limited by phone resources.

Does Rikkahub store my API keys or conversation history on a server?

API keys are stored locally on your device within the app. Conversations are also stored locally by default. Rikkahub operates no backend server that receives your keys or messages; requests travel directly from your device to the AI provider's API endpoint. The AGPL-3.0 source is auditable if you want to verify this.

Is there an iOS version of Rikkahub?

No. Rikkahub is an Android app. A web interface is available for browser access on other devices, but there is no native iOS app from this project.
