Pagy is the ultimate pagination gem that outperforms the others in each and every benchmark and comparison.

New in 3.0+

  • Pagy 3.0+ is considerably faster, lighter and more efficient than 2.0+ on modern environments (see the charts below)
  • The javascript nav helpers have been refactored for improved performance and more intuitive API
  • The i18n has been refactored, the dictionary files are simpler and 100% compliant with the i18n gem
  • Added a few new extras
  • Added Maximizing Performance docs as a practical guide to choose the best options for your requirements and environment

Notice: Updating from 2.0+ to 3.0+ requires just some search and replace and a little reorganization of your custom i18n dictionaries. Check the CHANGELOG for details.


  • If you are using any pagy*_nav helper, consider to switch to pagy*_nav_js, which gives you the same output with a substancial performance boost.
  • If you are using any javascript frontend, take a look at the metadata extra
  • For API pagination take a look at the headers extra

Comparison with other gems

The best way to quickly get an idea about Pagy is comparing it to the other well known gems.

The values shown in the charts below have been recorded while each gem was producing the exact same output in the exact same environment. (see the Detailed Gems Comparison)

~ 40x Faster!

[IPS Chart](docs/assets/images/ips-chart.png)

~ 36x Lighter!

[Memory Chart](docs/assets/images/memory-chart.png)

~ 35x Simpler!

[Objects Chart](docs/assets/images/objects-chart.png)

~ 1,410x More Efficient!

[Resource Consumption Chart](docs/assets/images/resource-consumption-chart.png)

Each dot in the visualization above represents the resources that Pagy consumes for one full rendering. The other gems consume hundreds of times as much for the same rendering.

The IPS/Kb ratio is calculated out of speed (IPS) and Memory (Kb): it shows how well each gem uses each Kb of memory it allocates/consumes.


Straightforward Code

  • Pagy has a very slim core code of just ~100 lines of simple ruby, organized in 3 flat modules, very easy to understand and use (see more...)
  • It has a quite fat set of optional extras that you can explicitly require for very efficient and modular customization (see extras)
  • It has no dependencies: it produces its own HTML, URLs, i18n with its own specialized and fast code (see why...)
  • 100% of its methods are public API, accessible and overridable right where you use them (no pesky monkey-patching needed)
  • 100% test coverage for core code and extras

Totally Agnostic

  • The Pagy class doesn't need to know anything about your models, ORM or storage, so it doesn't add any code to them (see why...)
  • It works with all kinds of collections, even pre-paginated, records, Arrays, JSON data... and just any list, even if you cannot count it (see how...)
  • Pagy works with the most popular Rack frameworks (Rails, Sinatra, Padrino, ecc.) out of the box (see more...)
  • It works also with any possible non-Rack environment by just overriding one or two two-lines methods (see more...)

Unlike the other gems

  • Pagy is very modular and does not load any unnecessary code in your app (see why...)
  • It works even with collections/scopes that already used limit and offset (see how...)
  • It works with fast helpers OR easy to edit templates (see more...)
  • It raises real Pagy::OverflowError exceptions that you can rescue from (see how...) or use the overflow extra for a few ready to use common behaviors
  • It does not impose any difficult-to-override logic or output (see why...)
  • It also works on legacy systems starting from ruby 1.9+ and jruby 1.7+

Easy to use

After installing and including Pagy (see Quick Start), you can use it in a quite familiar way:

Paginate your collection in some controller:

@pagy, @records = pagy(Product.some_scope)

Render the navigation links with a super-fast helper in some view:

<%== pagy_nav(@pagy) %>

Or - if you prefer - render the navigation links with a template:

<%== render partial: 'pagy/nav', locals: {pagy: @pagy} %>

Easy to customize

Use the official extras, or write your own in just a few lines. Extras add special options and manage different components, behaviors, Frontend or Backend environments... usually by just requiring them:

Backend Extras

  • arel: Better performance of grouped ActiveRecord collections
  • array: Paginate arrays efficiently, avoiding expensive array-wrapping and without overriding
  • countless: Paginate without the need of any count, saving one query per rendering
  • elasticsearch_rails: Paginate ElasticsearchRails response objects
  • headers: Add RFC-8288 compliant http response headers (and other helpers) useful for API pagination
  • metadata: Provides the pagination metadata to Javascript frameworks like Vue.js, react.js, etc.
  • searchkick: Paginate Searchkick::Results objects

Frontend Extras

Feature Extras

  • i18n: Use the I18n gem instead of the pagy-i18n implementation
  • items: Allow the client to request a custom number of items per page with an optional selector UI
  • overflow: Allow for easy handling of overflowing pages
  • support: Extra support for features like: incremental, auto-incremental and infinite pagination
  • trim: Remove the page=1 param from the first page link

Alternative Components

Besides the classic pagination offered by the pagy_nav helpers, you can use a couple of more performant alternatives:

  • pagy_nav_js: A faster and lighter classic looking UI, rendered on the client side with optional responsiveness:[bootstrap_nav_js](docs/assets/images/bootstrap_nav_js-w.png)

  • pagy_combo_nav_js: The fastest and lightest alternative UI (48x faster, 48x lighter and 2,270x more efficient than Kaminari) that combines navigation and pagination info in a single compact element:[bootstrap_combo_nav_js](docs/assets/images/bootstrap_combo_nav_js-w.png)

  • pagy-cursor An early stage proget that implements cursor pagination for AR
