Mobile-first builder · Ranked 22 of 33 in the index
a0.dev Review (2026)
A chat-driven mobile app generator producing React Native and Expo projects, notable for how quickly it applies small changes and how little ceremony it demands.
3.6 / 5Last verified: · Next scheduled check: The quick answer
Assessed for 2026The deployment story is the reason to look at it, and we had understated it. a0.dev does full one-click publishing to the App Store and Google Play, including creating the App Store Connect listing and uploading the build for you, plus over-the-air updates afterwards. For a solo builder who has never fought an Apple submission, that is worth more than another point of design polish. What you should not assume is a backend. There is no a0 datastore: the vendor describes the backend as powered by Convex or Supabase, which you sign up for separately, so budget a second vendor from day one. Several cells on this page previously claimed capabilities the vendor does not publish, and they now say so plainly: authentication and GitHub sync are not published by the vendor as of August 2026, meaning we could not verify them either way rather than that they are absent. Custom domain is a real Pro feature, listed as custom domain and no a0 branding. One published weakness to plan around: Android in-app payments are explicitly not supported yet. There is still no public API and no MCP server.

The ten axes
Every builder in the index is scored on the same ten axes with the same published weights. This is how a0.dev performed on our test briefs.
- Reliability16%

- Integrations16%

- SEO and GEO13%
- n/a, not applicable

n/a means the axis does not apply to this tool. It builds internal software behind a login, a native store app or an API, so there are no public crawlable pages to test. The axis is left out of the overall rating and the remaining weights are renormalised, rather than the tool being scored down for something we did not test.
Every axis is scored from 0 to 5 stars. The percentage is that axis's published weight in the overall 3.6 rating.

The dissenting view
One panellist argued the scalability mark punishes a tool for not attempting something it explicitly does not sell, and that prototyping tools need their own axis weighting.
One member of the panel disagreed with the consensus. We publish the disagreement rather than average it away.
What it looks like
Pricing
No free tier is published. Pro is USD 20 a month and the only other plan is Max at USD 200 a month for 1,250 credits.
| Plan | Price | Billing | What you get |
|---|---|---|---|
| Pro | USD 20 | monthly | Monthly credits, code export, device preview |
| Max | USD 200 | monthly | 1,250 credits a month |
We list the plans we could verify on the vendor's own pricing page. Where a plan exists but its price was not published in a form we could capture, the row says so rather than carrying a number we cannot source.

| Code export | Yes, Expo project |
| GitHub sync | Not published by the vendor as of August 2026 |
| One-click deploy | Yes, full one-click App Store and Google Play publishing including creating the App Store Connect listing and uploading the build, plus over-the-air updates |
| Custom domain | Pro feature, listed as custom domain and no a0 branding |

What works / What does not
What works
- Full one-click App Store and Google Play publishing, including creating the App Store Connect listing and uploading the build
- Over-the-air updates after the first release

What does not
- No a0 datastore. The backend is powered by Convex or Supabase, which you sign up for separately

The tightest change-and-see loop I have used anywhere
DeShawn Price@deshawnprice
Solo founder of a fitness app with 900 paying users. Built it twice, second time properly.
Ask for a change, look at your phone, it is there. Nothing else I have tried is close on that one measure, and in the first two days of an idea that measure is the only one that matters. I would not run a company on it and I do not need to.
- Pros
- Iteration speed is genuinely unmatched.
- Cons
- No team features at all.

Perfect for two days, wrong for two months
Kenji Morisaki@kenjimorisaki
Contract mobile developer. Ships React Native and Flutter for clients who cannot decide.
Superb for exploring an idea, and I keep it for exactly that. There are no integrations worth the name, no API, and no collaboration, so a second person joining is where it ends. Export gives you an Expo project to continue elsewhere, which is the right escape hatch.
- Pros
- Fast, cheap and exports a real project.
- Cons
- Thin integrations and no way to work as a team.

Frequently asked
- Does a0.dev include a database?
- No. There is no a0 datastore. The vendor describes the backend as powered by Convex or Supabase, which you sign up for separately, so plan for a second vendor and a second bill.
- Can it publish to the app stores for me?
- Yes, and this is its strongest feature. One-click publishing to the App Store and Google Play includes creating the App Store Connect listing and uploading the build, with over-the-air updates afterwards.
- Does it handle payments?
- Not fully. Android in-app payments are explicitly not supported yet.
- Is there an API or MCP server?
- No. Neither is published, so a0.dev cannot be driven from an AI agent or a script.
