I build APIs for a living, and my localhost setup had become a junk drawer — one tool for local domains, one for traffic inspection, one API client, a mock server, a mail catcher. Bifurc is all of that in one free desktop app:
🔀 Proxy — every local service gets a *.localhost name with HTTPS; capture traffic from anything
🧪 API client — REST, GraphQL, gRPC, SOAP, WebSocket, SSE, Socket.IO, MCP, webhooks
🎭 Mocks — served at the proxy layer, with scenarios and contract checks against the real API
🌊 Flows (new!) — chain requests visually, branch and loop, load-test, or generate a flow from captured traffic
📬 Mail inbox (new!) — a local SMTP catch-all that extracts sign-in codes and links from your app's email
🤖 Agent CLI (new!) — a command line built for AI agents, with a policy file that can deny calls or hold them for human approval
Everything stays on your machine: workspaces sync through your own git repos, and secrets are stored as encrypted vaults. It's built entirely in Rust — no Electron — and this release adds the first macOS builds next to Windows and Linux.
Free, no account, no paid tier. It's early-stage — I built it for my workflow, use it daily, and I'm fixing and refining it as I go. I'd love your feedback — especially what your current setup does that Bifurc doesn't yet.
Everything local is what got me in, no account thats good. Instead of jumping between tools, this covers most of my use cases. The vault handles all my secrets, and that's been a great feature for me. Are the audit logs stored locally? Anyway, can I export them without syncing those to the workspace?
I tried this and it is truly a time saver for me. Time to ditch postman and get onto Bifurc. I don't like the name but the app is great and fast. Gets the work done quick.
@pratikstemkar Thanks for using the app but almost all names are taken
