BridgeSpace 3 is an agent development environment built for developers who want to run multiple AI models concurrently without juggling tabs, terminals, or separate tools. You can spin up to 16 agents in parallel — mixing Claude, Codex, Gemini, and Cursor in one window — and let the Bridge Agent handle orchestration across your swarm. A built-in browser and IDE eliminate the need to switch context: write, run, and test inside the same workspace. Workspaces spin up in under a second, which matters when you're iterating fast or debugging agent interactions. Best suited for developers building AI-powered products, prototyping multi-agent pipelines, or anyone who finds single-model workflows a bottleneck.
