Comparison
Frontman vs Stagewise
Agentic Desktop IDE vs Browser-First Framework Agent
Frontman and Stagewise both connect AI coding agents to rendered applications and real source files, but they package that workflow differently.
Frontman is a source-available AI coding agent with a distributed architecture. Browser tools inspect the page, the local framework integration (Next.js, Astro, Vite) provides component and filesystem context, and the server orchestrates the agent loop and persists task history. Free and unlimited — you bring your own API keys.
Stagewise is a standalone open-source AGPL-3.0 agentic desktop IDE. Its agents operate directly on files across workspaces and pair a full browser engine for app previews and DOM element context with terminals, diff review, skills, plugins, and flexible provider configuration. External IDE integration may remain available, but it is not the whole product. Limited to 10 free prompts/day (€20/month for 100/day).
Choose Stagewise for an open-source agentic desktop IDE with broad workspace, browser, terminal, and extension tooling. Choose Frontman for browser-first collaboration, no prompt caps, and explicit framework runtime mapping.

What Stagewise Does Well
Stagewise has evolved into a complete open-source agentic development environment rather than a browser toolbar accessory.
Direct workspace agency. Agents operate on the filesystem across workspaces, with integrated terminals and a diff-review flow for inspecting changes before acceptance.
Browser engine built in. App previews live inside the IDE, and DOM elements can be supplied as precise visual context instead of relying only on a textual description.
Flexible models and deployment. Stagewise supports direct BYOK, imported subscriptions, custom providers, and local models through Ollama, LM Studio, OpenAI-compatible, and Anthropic-style APIs. The AGPL-3.0 project is self-hostable.
Extensible environment. Skills and plugins expand the agent's workflows. External IDE integration can complement the desktop product for teams that keep another editor in their toolchain.
Where Frontman Is Different
Frontman and Stagewise both combine browser context with source edits. The useful distinction is how they integrate that context into development.
Framework runtime integration vs desktop workspace. Frontman installs as a plugin into your dev server — @frontman-ai/nextjs, @frontman-ai/astro, or @frontman-ai/vite. This explicitly maps rendered elements to the framework component tree, props, server-side routes, logs, and query timing. Stagewise has broad filesystem, terminal, preview, and DOM access, but its current sources do not establish equivalent framework runtime/component mapping.
Self-hostable and BYOK. Stagewise's free tier caps you at 10 prompts per day. Their Pro plan is €20/month for 100 prompts/day. Frontman remains free to self-host under its source-available licensing terms. Hosted Frontman Pro is available now. Self-hosting places server orchestration and persistence on your infrastructure; context still goes to your configured LLM provider. You bring your own API keys and pay your LLM provider directly.
Browser-first collaboration. Frontman does not require moving the team into a new IDE. Designers, PMs, and developers work from the running app in their normal browser while source edits flow through the local integration.
Purpose-built runtime context. Frontman connects client-side DOM and computed styles to framework component metadata and server-side signals. Stagewise can inspect DOM elements and operate through files and terminals; only the Frontman-equivalent runtime mapping is not established by current sources.
Provider choice on both sides. Frontman connects directly to Claude, ChatGPT, OpenRouter, or OpenAI-compatible APIs. Stagewise now also supports direct keys, imported subscriptions, and custom or local providers.
Who Should Use Stagewise
Stagewise is the better choice when you want a complete open-source agentic desktop environment:
- Unified agent workspace — want filesystem edits, app previews, DOM context, terminals, and diff review in one desktop IDE
- Extensible workflows — want skills, plugins, and optional external IDE integration
- Custom or local models — want direct keys, imported subscriptions, Ollama, LM Studio, or compatible API endpoints
- Occasional use — 10 prompts/day is enough for your workflow and you don't want to manage API keys
Who Should Use Frontman
Frontman is the better choice when you need deeper integration and freedom from prompt limits:
- Daily frontend development — 10 prompts/day isn't enough and you don't want to pay €20/month for a cap of 100
- Next.js, Astro, or Vite projects — Frontman's middleware explicitly maps browser elements to framework runtime context
- Teams with designers or PMs — non-technical team members can make visual changes without an IDE or a Cursor subscription
- Source-available and vendor-independent — you want infrastructure control, BYOK, and a self-hostable development workflow
- Server-side context matters — you need the AI to understand routes, server logs, and server-side state alongside the visual UI
If you hit Stagewise's prompt limits or need explicit framework runtime/component mapping, Frontman is worth evaluating.

Frequently Asked Questions
What is the difference between Frontman and Stagewise?+
Stagewise is a standalone open-source agentic desktop IDE. Its agents work directly on files across workspaces, with an integrated browser engine, terminals, diff review, skills, and plugins. Frontman runs alongside your existing editor and integrates with Next.js, Astro, or Vite to connect browser inspection with framework runtime context. Both can inspect rendered UI and edit source files; current Stagewise sources do not establish Frontman-equivalent framework component and runtime mapping.
Is Frontman a self-hostable alternative to Stagewise?+
Both are self-hostable, with different architectures and licenses. Stagewise is an AGPL-3.0 desktop IDE. Frontman can be self-hosted under its source-available licensing terms, and you bring your own API keys to Claude, ChatGPT, or OpenRouter. Self-hosting moves orchestration and task-history persistence to your infrastructure but does not prevent transmission to your configured LLM provider. Hosted Frontman Pro is available now, while self-hosting remains available.
Can I use Stagewise and Frontman together?+
Potentially. Stagewise is a standalone desktop IDE whose agent edits the workspace directly, while Frontman runs through browser tools, a local framework integration, and its own agent server. Because both can edit the same source files, coordinate tasks and review diffs to avoid overlapping changes.
Does Frontman work with Cursor like Stagewise does?+
Frontman is a self-contained agent that does not require Cursor or another IDE. You can still use Cursor alongside Frontman because both edit the same source files. Stagewise may integrate with external IDEs, but that integration is one option within its broader standalone desktop IDE rather than the whole product.
Which tool has deeper browser context?+
They expose different context. Stagewise includes a full browser engine for app previews and DOM element context. Frontman combines live DOM and computed styles with framework integrations that map rendered elements to component-tree, props, routes, logs, and other runtime context. Current Stagewise sources do not establish equivalent framework runtime or component mapping, so the distinction is narrower than browser access versus no browser access.
Which tool is easier to set up?+
Stagewise is installed as a standalone desktop IDE and works directly with local workspaces. Frontman requires installing a framework adapter (e.g., npx @frontman-ai/nextjs install for Next.js) which adds a small amount of middleware to your dev server. Setup choice depends on whether you want a complete agentic IDE or browser-first tooling integrated with your existing editor and framework runtime.
