AI app builders, compared honestlyWhat each one gives you free, how you pay, and who holds your code. Every line about another product is from its own pages, with the link.SPOE

Free to start. 50 credits when you sign up and a daily top-up to 30, no card. A build on the default models costs about 10 to 30 credits.

Paying. No subscription. Credit packs from A$19 for 5,000 credits, used as you go, at each model's 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 carries an Ed25519-signed provenance manifest and the verifier that checks it, offline or at spoe.ai/verify, in your browser.

Runs without us. An export is a Next.js, Fastify and Postgres project that starts with docker compose up and has no SPOE dependency inside. CI proves that on every commit.

Safety. Every change is reviewed by a second model from a different model family before it lands. A flagged change waits for you.

Privacy. Models run on Venice's private inference, which keeps no copy of prompts or outputs. Chats, bots and images stay in your browser.

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