Run the best Nostr Experience running at
https://poster.place, PosterChan, on your own hardware easily in Docker!
The Nostr core
- Built-in web-of-trust relay (PostgreSQL-backed) that doubles as the database
- Full cyberpunk Nostr web client — feed, profiles, DMs, notifications, articles, communities. PWA + Android APK + desktop app that runs with no server at all, just relays and a key
- Built-in Blossom media server (BUD-01/02/06)
- Git over Nostr — browse announced repos, or host your own with a built-in GRASP server, web UI and an editor that commits
- A password manager and cross-browser bookmark sync where your own relay is the backend — Firefox/Chrome/Brave extension, AES-GCM encrypted per-item events, TOTP codes, autofill, plus a NIP-07 signer so you log into Nostr apps without pasting your nsec
AI on your hardware
- Streaming chat + OpenAI-compatible /v1/ with function calling, so agentic coding tools point at your box
- Native llama.cpp on CPU / CUDA / ROCm / Intel Arc SYCL, round-robin load-balanced across machines
- Image (SDXL), music (ACE-Step), video (Wan/LTX/CogVideoX), TTS/STT
- Zero-shot voice cloning — a few seconds of audio, then it speaks your text in that voice
- Talking pictures — a still face lip-syncing a line in that cloned voice, and it works on drawings
Real-time
- Voice/video calls — WebRTC, signaled over Nostr, works across instances, built-in TURN
- Live streaming from OBS — RTMP → HLS, announced via NIP-53, so it lands in the wider Nostr stream directories
Private by construction
- Encrypted Notes (offline-first, Joplin import) and a Budget — both encrypted to your key, so the server and the AI genuinely cannot read them
And the rest in one box: RSS reader, email, torrents, file manager, flashcards, reminders, meme builder + effects studio, Telegram bot, autonomous Pleroma/Nostr bots, and a fediverse ↔ Nostr bridge with write-back.
