What Spettro is
Spettro is an open-source, terminal-first coding assistant for planning repository work, approving steps, writing code, and resuming tasks. Its runtime assigns plan, coding, review, documentation, git, test, and explorer roles with explicit handoffs. Goal mode works through iterations, detects stalls, resumes progress, and signals completion. It supports Anthropic, OpenAI-compatible APIs, and local endpoints such as LM Studio or Ollama. The product also describes MCP support, Telegram control, and ACP integration for compatible editors; Zed is the listed supported IDE. Users can install skills from local folders or git sources and create slash commands and runtime hooks. API keys are encrypted locally with AES-GCM, and operator-configured OS sandboxing is offered on macOS, Linux, and Windows. Spettro says prompts and chat history are not stored on its servers, while inference messages are forwarded to model providers. For cloud features, it processes account email, subscription state, API-key hashes, and per-inference usage records. The Free plan costs nothing and includes all features with your own API key. Paid plans start at €5 / month: Lite is €5, Plus €10, Pro €20, and Max €150 per month, with stated token allowances and support varying by tier.
