Stagewise

Stagewise is the open-source agentic IDE for creating and orchestrating multiple coding agents simultaneously, showing app previews, and running git workflows. Founded as a browser-native frontend tool and significantly pivoted, Stagewise now positions itself as a multi-agent command center where developers run parallel agents each implementing full features or fixing bugs independently. YC S25 backed, incorporated as stagewise GmbH in Bielefeld, Germany. The core workflow: run multiple agents in parallel from the Stagewise desktop app (macOS), each operating in isolated contexts with full git workflow support and live app previews showing progress as changes are made. The platform achieves an average 87.6% cache hit rate through dynamic context control, enabling long-running multi-agent tasks at materially lower cost than tools that do not optimize cache usage. Model support covers all major providers: OpenAI, Anthropic, Google Gemini, DeepSeek, Qwen, Kimi, MiniMax, GLM, and more. Developers can use their own API keys (BYOK) or connect existing coding subscriptions including Claude Pro, OpenAI, and Google Gemini plans. No model lock-in. Open source under AGPL-3.0 with the full source on GitHub. Pricing includes paid plans via Stripe but no public pricing page as of May 2026. Developers should check the app for current plan details. The open-source repository is free to self-host under AGPL-3.0 terms, though commercial use requires license review. Data collection for service improvement requires explicit opt-in consent and is off by default per the privacy policy. Teams needing Windows support cannot use Stagewise yet, as downloads are macOS-only. Teams wanting an established multi-agent platform with commercial support and SLAs should evaluate Claude Code ($20/month) or Cursor ($20/month). AGPL-3.0 license has copyleft implications for teams embedding or distributing Stagewise in commercial products.
