SPOE, the vibe coding app builder: sign it, prompt it, own it, export itSPOE (spoe.ai) is a private AI app builder for vibe coding. Describe what you want, a model writes it into a real Next.js, Fastify and Postgres project, a plain HTML website or a browser game, and a second model from a different family reviews every change for security flaws before it lands.Every other builder in this category says you can export your code. SPOE signs it. Each export carries SPOE's Ed25519 provenance manifest and a record of it on APIR's hash-chained log, and spoe.ai/verify shows that no file has changed since and that spoe.ai signed it. It runs with docker compose up and no SPOE dependency inside.Make games, tooGame Studio makes browser games from a description: 2D with Phaser or 3D with Three.js, at the graphics and size you pick. Play it in the studio as it is built, then publish it to the Arcade for anyone to play.What you get

Free to start. One free build on the default models once your email address is proven (by Google or GitHub, or where email sign-up is open, a code we email you), no card. Your first payment of any size, a credit pack or a plan, opens every model, chat, pictures and export, for good. A build on the default model costs about 20 to 50 credits, and you see the estimate first.

Paying. A plan from US$25 a month for 6,000 credits every month (two months free by the year), or a credit pack bought once, from US$19 for 4,000 credits. Credits never expire, and each model is used at its own price.

Your code. Export a ZIP, or link a GitHub repo once: every version lands there as a commit, and commits made in the repo come back in.

Export, for good. Your first payment of any size unlocks export permanently, whether or not you ever pay again. Locked or not, the code is always visible and copyable in the editor.

Proof. Every export is signed: an Ed25519-signed provenance manifest from SPOE, with a record of it on APIR's hash-chained log. spoe.ai/verify checks every file and that spoe.ai signed it, in your browser; the verifier inside checks your own copy offline.

Runs without us. An export is a Next.js, Fastify and Postgres project, a plain HTML website or a browser game, that starts with docker compose up and has no SPOE dependency inside.

Safety. Every change is reviewed by a second model from a different model family before it lands. A blocked or unreviewed change, or one with a high or critical finding, waits for you.

Privacy. The default models run on Venice's private inference, which keeps no copy of prompts or outputs. Claude, GPT and Gemini run anonymized: Venice passes the request on without saying who you are. Chats, bots and images stay in your browser.

Hosting. Publish to <name>.spoe.dev, or to a domain of your own with automatic HTTPS.
