What is omg.dev?
omg.dev is an AI project builder tool. An AI builder for small apps and browser games, usable from a phone. The code is open source and can be self-hosted for free, while the managed version starts at $19 per month with a free trial and no card required.
omg.dev is a build environment for people who have an idea and little or no coding experience. From a browser (the marketing leans heavily on the phone case) a user describes an app or a game and the AI assembles it, aiming at projects that can be published and shared rather than left as a mockup. The homepage frames the product around two starting points: build an app, or build a game. The showcase includes small browser games and a trending-video digest app, which gives a fair picture of the scale it targets: compact single-purpose products rather than sprawling platforms. For developers, the pitch takes an unusual turn. The source code is public on GitHub, so anyone can self-host it, run it on a Mac or their own server, and plug in an agent subscription they already pay for. That means the tool is two products in one: a managed service where omg.dev operates the infrastructure, and a do-it-yourself stack for people who prefer to own the runtime. The managed tier starts at $19 per month according to the site, with a free trial and no card required to get started. Exact limits on that tier are not spelled out on the homepage. In practice, the workflow is prompt-led: state what the thing should do, review the generated result, then iterate. The listing below walks through the hosted route. Self-hosting is a separate path that assumes comfort with a terminal and an existing agent subscription. Compared with general-purpose coding assistants that assume a local repo and a developer at the keyboard, omg.dev narrows the scope to shipping small web apps and games. Compared with no-code site builders, it produces running code you can inspect and host yourself. The right buyer is a solo maker, hobbyist or product tinkerer who wants a first version quickly and values the option to take the code elsewhere.
How do you use omg.dev?
1Open the browser builder
Go to the app subdomain and start a new project. The builder is the hosted path; self-hosting from the GitHub repo is the alternative if you want to run everything yourself.
2Choose the kind of thing you are building
The homepage separates the starting points into an app or a game. Pick the one closest to your idea so the first prompt is scoped correctly.
3Describe the idea in plain language
Write what the product does and who uses it. Small, concrete features tend to survive a first build better than a long wish list.4Review the generated build and iterate
Run what comes back, note what is missing or broken, and ask for changes one at a time rather than rewriting the whole brief.5Publish and share a link
Once the build behaves, put it online from the managed service so others can open it. Live examples on the homepage show what published projects look like.6Compare plans or self-host
Check the pricing page for the managed tiers from $19 per month, or move to the GitHub repo and run the stack on your own machine with your agent subscription.
