A local-first agent framework.
Bring your own LLM. Bring your own API keys. The framework provides agent personas, tool execution, scheduled heartbeats, and channel delivery to Telegram, Slack, Discord, CLI, and your browser — all running on your machine.
OpenVesper isn't a chatbot. It's a framework for building agents that actually do work for you, on your schedule, in your tools.
Wake up to a 5-bullet summary delivered to Telegram. Crypto moves overnight, your calendar today, weather, macro releases.
Daily 8 AM digest, sent to your phone before you grab your coffee.
Monitor wallets you care about. Get pinged when a known whale moves > $1M, with the on-chain context already attached.
Telegram message: "Wallet 7xK...y3 moved 12,000 SOL to Coinbase."
Trending coins on Pump.fun, BonkFun, Bags.fm scored by liquidity, volume, holder distribution, and buy pressure.
Score > 80? Pinged. Below? Ignored. No noise.
GitHub webhook → agent reviews the PR → posts findings to your engineering Slack channel.
"PR #142 looks good except line 87 — possible SQL injection in raw query."
Every Friday at 5 PM, agent pulls your week's GitHub commits, calendar events, and tasks into a retro draft.
Saves 30 minutes of Friday afternoon scrolling.
Run everything on your machine. Use Ollama for fully offline, Anthropic for top quality, Groq for speed. Your choice.
No accounts, no sign-ups, no data shipped to anyone.
Six things that set this apart from chatbot SaaS products.
MIT licensed. Audit the code yourself — every line is on GitHub. No black boxes, no surprises.
Runs on your laptop, your server, your Raspberry Pi. We have no servers to depend on.
No telemetry, no analytics, no phone-home. Your prompts never leave your machine except to your chosen LLM.
Use any LLM provider. Anthropic, OpenAI, Groq, Gemini, DeepSeek, Ollama. Mix and match per agent.
OpenVesper never asks for your seed phrase or private key. Read-only crypto data, never signing.
Talk to your agents from Telegram, Slack, Discord. Bidirectional — they message you back when something happens.
Clone, install, build. Then head to the docs for agent-specific setup.
