If you want to build an app without coding, you have real options — Bubble, Glide, Adalo, FlutterFlow, and newer AI builders. They're each good at different things. Here's an honest comparison to help you pick, especially if you've never built anything before.
Full disclosure: we make OttoAndMe. We'll tell you straight where it fits — and where it doesn't.
| Tool | Best for | How you build | Learning curve | Teaches you | Beginner-friendly |
|---|---|---|---|---|---|
| OttoAndMe | First-timers building a real app, tool, or site — fast | Describe it in plain English; Otto builds it with you | Very low | Yes — explains the why | ★★★★★ |
| Bubble | Complex, custom web apps | Visual drag-and-drop + logic you design yourself | High | No | ★★ |
| Glide | Simple apps built from a spreadsheet | Connect a sheet, pick a layout | Low | No | ★★★★ |
| Adalo | Simple mobile apps | Drag-and-drop screens | Medium | No | ★★★ |
| FlutterFlow | Polished apps, closer to real development | Visual builder using developer concepts | High | No | ★★ |
Stars are our honest read for an absolute beginner — not overall power. Bubble and FlutterFlow can do far more than OttoAndMe; they just ask more of you.
OttoAndMe is the gentlest start. Plenty of people start here and grow with it — Otto builds in real React when projects get ambitious, takes real payments, and guides you through accounts and the app stores when you want them — that's a great path.
Most "no-code" tools hand you a blank canvas and a learning curve. OttoAndMe's difference is that Otto builds the thing with you — you describe what you want in plain English, Otto makes a working version, explains the why so you actually learn, and remembers you and your projects next time. First build takes minutes, there's no login to start, and everything you make is yours to keep — tap Save to download the actual file to your device and take it anywhere. You're not locked in.
No login to start. Free to try; $19/month for unlimited.
