AIby.email
Build and run AI agents you actually own on your Mac or server—free, open source.
If you're technical and want an AI agent that answers to you—no cloud, no subscription, no data leaving your machine—00 is a standout free option. It's not for casual users: setup requires CLI knowledge and key management, but for those who value control, it's a capable, open-source solution. Recent updates add remote fleet management, making it even stronger for developers already living in the terminal. Compare it to hosted platforms like Lindy or Relevance AI: those offer more hand-holding

Skip 00 if you're not comfortable with CLI, config files, and API key management, or if you need a hosted SaaS with support and uptime guarantees—this is a self-hosted, tinkerer's tool.
Some social channels like Instagram, X, and TikTok route through Overblast, which may require a paid subscription—check your channel list before committing.

Compared to hosted agent platforms like Lindy ($99+/mo) or Relevance AI (from $19/mo), 00 gives you unlimited agents for $0, but you provide the hardware and the technical elbow grease.

About AIby.email
00 (AIby.email, 0-0.chat) is a free, open-source macOS app with a headless engine for Linux, macOS, and Windows that flips the AI-agent model. Instead of renting a cloud service, you build and run as many agents as you want on your own hardware, with your own models, keys, and data. No cloud account, no subscription fee. It's built for developers, privacy advocates, and power users who want full control over their AI stack. Each agent gets its own brain, memory, files, contact book, and a pixel-art face, so you can assemble a crew of specialized agents—work, projects, home—without contexts mixing. Pick a brain per agent: local LLMs via Ollama, LM Studio, Jan, or cloud providers like Anthropic, OpenAI, Google Gemini, xAI (Grok), Groq, DeepSeek, Mistral, OpenRouter, Together, Fireworks, and Cerebras. You can even pool multiple Claude or Codex subscriptions on one agent and auto-rotate when an account hits its limit. Connect agents to 19 channels out of the box: WhatsApp, Instagram, Email, Phone calls, Telegram, Signal, iMessage, Slack, Discord, X, TikTok, Facebook, LinkedIn, YouTube, Reddit, Pinterest, Bluesky, Snapchat, Google Business, and web chat. Agents run on schedules via cron, transcribe meetings on-device with local Whisper, act as a support desk, manage social media, or drive iOS Simulators and Android emulators for mobile app testing. Security is baked in: an encrypted vault (AES-256-GCM) keeps API keys write-only, an isolated public agent sandbox walls off strangers, and on-device channels like Signal and iMessage keep messages local. The latest v26.0.x releases add fleet resilience, including server management from a hub, SSH key rotation, and auto-set concurrency. This is a powerful tool, but it demands technical comfort—expect config files, API key management, and a terminal-first mindset. Compared to hosted agent platforms, 00 gives you ownership and privacy, but less hand-holding.
Behind the Verdict
00 is the DIY enthusiast's dream and the non-technical user's nightmare. It's a free, open-source agent builder that puts you in the driver's seat—your hardware, your models, your data, no cloud account. For developers who already live in the terminal, the payoff is real: you get a personal crew of agents each with its own brain, memory, and channels, all running locally or on your own server, with zero recurring fees. When should you pick it? If you're comfortable with CLI tools, config files, and managing API keys, and you value privacy and ownership over convenience. The new v26.0.x fleet features—server management from a hub, SSH key rotation, concurrency auto-set—make it even more attractive if you're running agents on remote boxes. You can pool multiple Claude or Codex subscriptions and let the agent auto-rotate when one hits its limit, which is a clever way to stretch paid accounts. When should you pass? If you want a plug-and-play email assistant or a hosted SaaS with support and uptime guarantees, 00 isn't for you. Setup is technical: you'll be editing configs and managing keys. There's no built-in collaboration for teams—each agent is single-user by design. And while open source means transparency, it also means you're on your own for troubleshooting beyond community support. The closest alternative is a hosted platform like Lindy or Relevance AI, which offer more hand-holding, pre-built templates, and visual builders, but at a monthly cost and with your data in their cloud. 00 trades that convenience for total control. It's a trade-off that makes sense for privacy advocates and technical founders, but not for someone who just wants an AI to book meetings. Real-world caveats: expect a learning curve. The notch-based UI is slick on macOS, but the headless

Models Under the Hood
as of 2026-08-27
Limitations
- 00 is a free, open-source platform that runs on your own machines—the macOS app or a headless engine for Linux, Windows, and servers.
- Setup requires technical comfort, including CLI usage and API key management.
- Local AI models rely on your machine's resources; cloud models need internet and may incur third-party costs.
- Some social channels (Instagram, X, TikTok, etc.) route through Overblast, which may require a paid subscription.
- The project is maintained by an independent developer, so support is community-driven and there's no official SLA.

Solo developer: under 15 minutes to install, pick a brain, and connect your first channel—expect more time if you go with local models. Privacy-focused freelancer: 30 minutes to configure a local LLM and native channels. Small team: an hour to set up headless engines on servers and manage via the hub.
Switching to or from AIby.email
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hosted agent platforms (Lindy, Relevance AI): export your agent workflows, then rebuild them as skills in 00—you'll keep your API keys but lose the SaaS conveniences.
- →From a bare LLM chat client: you're not migrating, you're upgrading—add channels, cron, and a per-agent workspace to what you already do.
- ↗To a hosted agent platform (e.g., Lindy, Relevance AI): your skills and channels won't transfer directly—you'll need to rebuild workflows in the new tool's builder.
- ↗To a different local framework (e.g., LangChain): export your agent configurations and scripts, then re-implement them in the new framework's orchestration.

Aiby Email vs Poke Interaction Co
If you live in your email and need automated replies, scheduling, and task extraction, AIby.email is the focused, affordable pick at $12/mo.
