Bolt.new alternative · for Rails teams
One Rails app to build on, not a second JavaScript one
Bolt.new generates a React app you export and maintain. Avo keeps your admin inside the Rails app you already run. Compare the two for internal tools.
Bolt.new is the most developer-friendly of the prompt-to-app tools. It builds in the browser, the code is real React and TypeScript, and you can export it to GitHub and keep it. That's a genuine strength. It's also the catch: what you keep is a second app, in a stack that isn't the Rails one your team runs, with its own deploy target, frozen the day you export it. With Avo, you build the same admin inside the app you already operate.
credit where it's due
What Bolt.new is genuinely great at
Of the app generators, Bolt is the one that respects that you might actually read the code. It runs a full toolchain in the browser, shows you every file from the first second, and hands back standard, editable code rather than a black box. For prototypes, front-end-heavy tools, and anything you'll throw away or hand to a JavaScript team, it's a strong choice.
Real, transparent code
It generates conventional React, TypeScript, and Tailwind you can inspect from the start, then download as a zip or push straight to GitHub. No proprietary format to escape from later.
Fast front ends and prototypes
Dashboards, admin-style screens, and interactive tools come together quickly, right in the browser, with hosting and custom domains a click away.
A good fit for JavaScript shops
If your team already lives in React and Node, Bolt's output lands in a stack you know. The friction we're about to describe is a Rails-team problem, not a universal one.
exporting the code isn't the finish line
You export it, then you run two apps in two stacks
"You keep the code" sounds like the end of the story. For a Rails team it's the start of a second one. That exported React and TypeScript project is a whole second application, started from zero: its own dependencies, its own build and deploy pipeline, its own auth and permissions, and its own data layer that has to talk to the database your Rails app already owns. It's frozen the day it's exported: nothing improves underneath it unless you prompt for it, and every change is a new screen to steer and review.
export from Bolt.new
The app you now run
- A React, TypeScript, and Node codebase separate from your Rails app
- Its own dependency tree and security patches
- A second deploy target to run and monitor
- Auth and permissions generated fresh for this one app
- Data access that has to reach your existing database
build with Avo
A foundation you build on, not maintain
- Plain Rails inside the app you already run
- The foundation is kept secure and up to date by the Avo team
- No new deploy target: it ships with your app
- Your existing auth and Pundit policies
- Reads your real ActiveRecord models directly
This is the two-apps problem in miniature. No company ever won its market because the admin panel was great, so the smart move is to build as little of that second app as you can. Bolt generates all of it, in a language your team may not even write. Keep the agent you already use and point it at Avo instead: with the docs and the skills that ship in the gem, it writes the admin in Ruby on a foundation that already exists, reviewed like any other change in your repo.
side by side
A Bolt.new app vs an Avo admin
| A Bolt.new-generated app | Avo | |
|---|---|---|
| Stack | React and TypeScript | Ruby on Rails, the stack you already run |
| Where it runs | A separate app on its own deploy target | Inside your existing Rails app |
| Your data | A data layer you connect to your database | Your existing models, read directly |
| Who maintains the framework | No one: it's frozen once exported | The Avo team, on a public roadmap |
| In your git history | Yes, once exported to GitHub | Yes, native to your repo |
| Pricing | Subscription plus your own hosting | Per app, unlimited users |
to be clear
When Bolt.new is the right call
If your team writes JavaScript, or you want a standalone prototype you'll host on its own, Bolt is a fine pick and its exportable code is a real advantage. This page is for Rails teams weighing a second stack against building the admin where their product already lives. If your production app is Rails, the export you'd be proud to keep is also a second app that starts from zero and freezes on export.
Frequently asked questions
- Can I build an admin panel with Bolt.new?
- Yes. Bolt.new generates a working admin-style app from a prompt, usually React, TypeScript, and Tailwind, and lets you export the code to GitHub or host it directly. It's one of the more developer-friendly generators. The trade for a Rails team is that the result is a separate JavaScript application, started from zero, to deploy and run alongside the app you already have.
- Bolt.new gives me the code, so why use Avo instead?
- Having the code is the start of the work, not the end. An exported Bolt app is a second codebase in React and Node, with its own dependencies, deploy pipeline, and auth, and it stops improving the day you export it. Avo runs inside your existing Rails app, reads your real models and Pundit policies, and the foundation keeps improving underneath your code, so you keep one app instead of two.
- Is Avo a good fit if my product runs on Rails?
- That's exactly who Avo is for. When your app is already Rails, an internal tool in React and Node means a second stack, a second deploy, and a data layer bridging back to your database. Avo builds the admin in the framework you already use, so there's nothing new to host and no second language for your team to work in.
- Do I lose AI speed by choosing Avo over Bolt.new?
- No. Keep the agent you already use and point it at Avo: more than 30 skills ship inside the gem and Avo's docs are machine-readable, so it writes resources on a foundation that already exists, directly in your Rails app. Your tokens, time, and focus go to the product instead of a second app in another stack.
- How does maintenance compare between a Bolt.new app and Avo?
- A generated app is frozen the moment it exists: dependency patches, security fixes, and every future feature arrive only when you prompt for them. With Avo, the foundation is maintained by the team behind it, vetted across 250+ paying companies and roughly 2.7M downloads of the avo gem, and improvements arrive on a public roadmap while your agent keeps working on the product.
- What does Avo cost compared to Bolt.new?
- Avo 4 is priced per app with unlimited users, and it runs on the hosting your Rails app already uses, so there's no extra infrastructure line item. Start a free trial, or explore the live demo first.
Build the admin where your product already lives
Skip the second stack. The admin Bolt would generate in React, your agent builds on Avo from the Rails models you already have, in the repo you already review, on the deploy you already run.
