Rails admin gems
Find the best Rails admin gem for your app
Most teams pick an admin gem once and live with it for years. Here's what each one does well and when it's the right pick.
Which Rails admin gem should you use?
If your admin will grow into the place your team runs the business from, with dashboards, actions, fine-grained permissions and a UI your support team likes, pick Avo: its Community edition is free and open source. If you need plain CRUD over a few models that won't change much, Administrate or Rails Admin will serve you well for free, and an Active Admin install that already works is fine to leave alone.
- Avo
-
Resources, fields, actions and policies in plain Ruby, on Hotwire, ViewComponent and Tailwind. Dashboards, filters and authorization come built in, and the same permissions hold when your team or their AI tools reach your data, whether through the in-app AI chat, the API, the MCP server or the CLI. More than 30 agent skills ship in the gem so your coding agent writes the Avo version you run. Community is free; paid plans are priced per app with unlimited users.
Pick it when your admin will keep growing, or your team works in it every day.
- Active Admin
-
The longest-running Rails admin gem, with its own DSL and a plugin ecosystem built up over a decade.
Pick it when you already run it, it works, and you're not planning to add much.
- Rails Admin
-
Generates an admin from your models with almost no configuration.
Pick it when you want a working CRUD tool today, you're on Sprockets, and you don't expect to customize it much.
- Administrate
-
thoughtbot's minimal admin. Dashboards are Ruby classes, and you override the views when you need something different. Free and MIT-licensed.
Pick it when you need simple CRUD over a handful of models, and that's likely to stay true.
- Trestle
-
A lightweight admin framework with a compact DSL per resource.
Pick it when you want a small admin and like defining it in a short DSL.
- Madmin
-
Chris Oliver's MIT-licensed admin and the one Jumpstart Pro ships with. Close to Rails scaffolds, with search, scopes, filters and nested forms on Hotwire and import maps.
Pick it when you're on Jumpstart Pro or want a free, scaffold-like admin, and you're happy to write actions and permissions yourself.
- Motor Admin
-
An admin you configure in the browser rather than in code, with SQL queries and dashboards built in.
Pick it when the people shaping the admin would rather use a no-code UI than Ruby files.
Avo vs hosted builders and app generators
Rails teams also weigh Avo against tools from outside the Rails world. Here is where each one puts your admin, and what that costs you later.
| Alternative | What it is | Why Rails teams pick Avo | Comparison |
|---|---|---|---|
| Retool | Hosted app builder that reaches into your database from outside. Per-seat pricing: $10 to $50 per builder per month, with end users billed separately (as of July 2026). | The admin lives in your Rails codebase, uses your models and policies, and is priced per app with unlimited users. | See the comparison |
| Forest Admin | Hosted admin frontend paired with an agent in your app, configured on their platform. Priced per user, last publicly listed at $60 per user per month (May 2026), now quote-based. | The entire admin is Ruby in your repo: versioned in git, reviewed in pull requests, deployed with your app. | See the comparison |
| Replit | AI agent that generates an internal tool from a prompt, typically as a separate app on Replit's stack. | A maintained foundation inside the Rails app you already operate, so your agent builds on it instead of a second stack. | See the comparison |
| Bolt.new | AI builder that ships full-stack JavaScript apps in the browser, a second codebase in another stack. | No second stack to run: the models you already have become a working admin without leaving your app. | See the comparison |
| Lovable | Prompt-to-React app builder: a separate app on its own back end that you change by re-prompting. | The admin is code in your Rails repo that a framework team keeps maintained, upgrade after upgrade. | See the comparison |

Still having doubts?
- What is the best Rails admin gem?
- For an admin your team works in every day and that keeps growing, we'd pick Avo, and yes, we're biased. It's plain Ruby in your repo, with dashboards, actions, filters and authorization built in, and Community is free. For simple CRUD that won't change, Administrate or Rails Admin is a fair choice.
- Is there a free Rails admin gem?
- Yes, several. Active Admin, Rails Admin, Administrate and Trestle are free and open source, and so is Avo Community. Avo's paid plans add more on top and are priced per app with unlimited users, so the bill doesn't grow with your team. See what each plan includes.
- Should I stay on Active Admin or Rails Admin?
- If it works and you rarely touch it, staying is reasonable: both are mature and battle-tested. Moving pays off once you want charts, richer fields, fine-grained authorization, or a UI your team enjoys using. Avo mounts next to your current admin in the same app, so you can rewrite your admin one resource at a time. If Active Admin is what you run today, start with the ActiveAdmin alternative comparison.
- Can I customize a Rails admin gem?
- Every admin gem gets you started fast and makes some customization harder. With Avo you override a field or a view, eject a component, or drop to plain Rails when the defaults don't fit, so changing one screen doesn't mean fighting the framework.
- Why use an admin gem when my coding agent can build one?
- Your agent can write one, but every generated admin is another app to maintain for as long as it runs. It spends tokens rebuilding the tables, forms, search and permissions every app needs, and its security and data integrity are only as good as the review it got. On Avo the agent writes the resources specific to your business and you review a short diff, while authorization, validations on your own models and upgrades come with a foundation already running in hundreds of apps.
