Show your work
The agent plans before it touches anything, cites what it looked up with built-in web search, and keeps every tool call visible. No black boxes — you can always see what it did and why.
About
Software should be buildable by anyone with an idea.
Gate 15 is an AI workspace for building real apps. Describe what you want, pick the AI you trust, and watch it come to life in a private, isolated space with a live preview — with the AI working out in the open the whole way.
Why we built it
For most people with a good idea, the gap between “I know what I want” and a working app has always been enormous. You needed to set up a machine, learn a stack, wire up a dozen services, and keep it all running. AI changed what’s possible — but a chat box that hands back a wall of code you can’t run, can’t see, and can’t trust isn’t the answer. We built Gate 15 to close that gap properly.
So we gave every project a real machine. Not a shared container or a disposable browser tab — its own private virtual machine, with a real filesystem, real dependencies, and a live preview you can open and click through. The AI builds in that machine the way an engineer would, and you watch it happen.
We also refused to make the AI a black box. It shows its plan before it changes anything, cites what it looked up when it searches the web, and keeps every tool call and result visible. You choose the model you trust for each step — Claude, GPT, Gemini, or GLM — and nothing deploys or pushes to GitHub until you decide it should. The result is software you can actually understand and stand behind, not output you have to take on faith.
Gate 15 is an independent product, built by a small team and answerable to the people who use it. That independence is why we don’t tie you to one AI vendor: the model that’s best today may not be best next quarter, so switching is a click, not a migration. The conviction underneath is simple — the people closest to a problem should be able to build the tool that solves it. We’re here to make that real.
What we believe
The principles we build on.
These aren’t posters on a wall — they’re the decisions baked into how the product behaves on every project.
Trust by default
Each project runs in its own private VM, secrets stay encrypted, and anything risky is flagged for your approval. Safety isn't a setting you switch on — it's how the product works.
Build in the open
You stay in control of every step. Plans are yours to approve, edit, or reject; nothing deploys or pushes to GitHub until you say so. The AI is a collaborator, not an autopilot.
Craft over hype
We'd rather ship one feature that genuinely works than a demo that falls apart on the second prompt. We verify against current provider docs and fix root causes, not symptoms.
Your choice of AI
Claude, GPT, Gemini, and GLM all live in the same workspace. Pick the model you trust for the job, or let Auto route each step to the right one. You're never locked into a single provider.
Ship, don't stall
Ideas are cheap; getting to something real is the hard part. A live preview, one-click deploys, and checkpoints to rewind from mean you keep moving instead of getting stuck.
How it actually works
Real machines, in the open, your way.

providers in one workspace — Claude, GPT, Gemini, GLM
1 VM
per project — a real, isolated machine
Plan-first
the agent shows its plan before it builds
You ship
deploys and pushes happen only when you say so
