Spettro review
A low-cost, open-source coding agent for Zed users who want multi-agent workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Spettro is an open-source AI coding assistant built for agent-driven work in a terminal or desktop app. It targets developers who want multi-agent delegation, autonomous goal runs, planning and approval before code changes, repository search, diagnostics, and persistent sessions across macOS, Linux, and Windows. Its runtime includes plan, coding, review, documentation, Git, test, and explorer roles, alongside skills, memory, custom slash commands, and hooks.
Pricing is structured from a €0-per-month Free plan to paid tiers at €5, €10, €20, and €150 per month. Free includes all features, multi-agent and MCP support, Ultra mode agent swarm, workflows, community support, and bring-your-own API key access. Lite adds Spettro-hosted models, standard response speed, and up to ~50M tokens per month. Plus raises the allowance to ~100M tokens and adds faster responses, per-repository agent manifests, hooks, command policy, and priority email support. Pro provides up to ~200M tokens, the fastest response speed, unlimited SuperFast after quota, early feature access, and dedicated support. Max raises the allowance to ~1.5B tokens and adds all current and future models, unlimited SuperFast after quota, an SLA guarantee, and a dedicated account manager.
The product’s standout strength is breadth within an agent workflow: approval-aware execution offers ask-first, restricted, and yolo modes; OS sandboxing uses Seatbelt, Landlock, and Mandatory Integrity Control; and tools cover web search, fetching, downloads, screenshots, and interactive PTY sessions. Provider support spans Anthropic, OpenAI-compatible APIs, LM Studio, Ollama, and local models, while ACP connects it with compatible editors such as Zed. Choose Spettro for terminal-first, configurable multi-agent development and low-cost hosted plans. Developers seeking broad editor coverage beyond the listed Zed integration should consider an alternative.
