One scoreboard. Twelve tools. 12 surfaces a real engineering team needs around the agent.
Every other Anthropic-ecosystem tool wraps the SDK and inherits its permission model. Mstro replaces that with a custom orchestration substrate built around a two-layer Security Bouncer.
Decides what is safe in milliseconds, no Allow prompt in your way. Plus stall detection, adaptive watchdogs, and checkpoint-and-retry so a hung tool does not kill the run.
PM Board, Quality, Files, Git, Terminal, view-only Sharing: every surface a real engineering team needs around the agent. Cursor 3, Devin, and Replit each ship a fragment; Mstro ships the set.
Mstro on the left. The field on the right. Hover any feature for what it does.

Twelve tools, one verdict each. The category badges show what shape they are; the line below explains where Mstro sits next to them.
AI-first VS Code fork plus Cursor 3, an agent-first interface. Both inherit the SDK permission model: prompt-on-every-call or yolo. No PM board, no Quality view, no view-only Sharing.
Mstro adds the productivity surfaces Cursor 3 left out (PM Board, Quality view, Sharing) and lets multi-hour runs actually finish.
Anthropic's official CLI and the SDK every competitor wraps. Prompt-per-tool out of the box or flip on dangerous-skip-permissions. Neither runs unattended.
Mstro is the orchestration substrate above Claude Code: browser UI, many sessions, and unattended multi-hour runs.
Claude.ai and Claude Desktop are chat apps with MCP. Great for conversation. They do not edit your repo, run your tests, or ship PRs.
Mstro runs Claude Code against your real repo on your machines, not in a chat window.
OpenAI's coding agent, a thin shell over the OpenAI SDK. Approval-mode flags loosen safety wholesale; runs on your terminal or in a ChatGPT cloud sandbox.
Mstro is the Anthropic-side equivalent, engineered for unattended multi-hour runs on your hardware.
Autocomplete and chat inside VS Code, JetBrains, and Visual Studio. Copilot Workspace agent mode wraps the Anthropic SDK and inherits its permission model.
Mstro operates one level up: parallel agents on worktrees, finishing while you are gone.
JetBrains AI Assistant is chat plus completions. Junie is the autonomous agent. Both wrap the Anthropic SDK and inherit its permission model.
Mstro is editor-agnostic, browser-based, and runs unattended for hours.
Cognition's autonomous engineer. Submit a task, it works in their cloud sandbox, you review the PR. The trust model is theirs and your code lives in their environment.
Same walk-away experience, but on your hardware under your trust boundary.
Codeium's VS Code fork with Cascade, an agent that plans and edits across a project. Wraps the SDK, inherits its permission model.
Mstro runs N agents in parallel for hours unattended, not one Cascade session at the keyboard.
Open-source VS Code extension running an AI agent inside the editor. Thin SDK wrapper; safety levers are prompt-per-tool or auto-approve-everything.
Mstro is many agents in parallel, in a browser, on any machine. Cline is one agent at your keyboard.
Cloud IDE with an Agent feature. Excellent for prototyping when your project lives in Replit's sandbox. Wraps the SDK inside that sandbox.
Mstro works on your existing local repos with your existing git remotes; Replit makes you start inside theirs.
Prompt-to-preview app builders for non-developers. They generate a project, host it in their cloud, and let you iterate in a web preview.
Mstro is for professional developers with existing repos, not for users starting from a template.
OSS terminal pair programmer. Pairs with your git repo, stages commits, edits files. Minimalist, free, single hands-on chat at a time.
Mstro is the heavier substrate above: parallel agents, browser UI, and unattended hours.
