Panes
Tiny, framework-agnostic library for Cupertino-style modals, cards, and panes.
If you need a tiny, dependency-free modal library that works across any stack, Panes is a solid pick. It lacks built-in accessibility audits and complex nested modals, so skip it for enterprise UI systems. Consider alternatives like Headless UI or Radix for more accessible, framework-native modals.

What people actually say about Panes — is it worth it?
We scanned public community sources for Panes on Jul 3, 2026 and could not establish that the discussion we found is about this tool rather than something else sharing its name. Our own analysis of that scan says the posts were off-subject. Rather than publish a sentiment score built on the wrong subject, we publish nothing here and re-run the scan.

About Panes
Panes (Cupertino Panes) is a free, open-source JavaScript library for building dynamic modals, cards, and panes that work with any front-end framework—Svelte, Vue, React, Angular, Elixir, or vanilla JS. At just 12KB minified and gzipped with zero dependencies, it's built for performance. The library offers Cupertino-style sheet, bulletin, and inversed modal panes, smooth animations, and light/dark appearance. Its codebase is AI-assisted, and the project is sponsored via Open Collective. Perfect for developers needing iPhone-style floating panels without heavy framework-specific bloat.
Behind the Verdict
Panes is a niche utility that does one thing well: giving you Cupertino-style panes, modals, and cards with a tiny footprint. At 12KB gzipped and zero dependencies, it's a real win for performance-conscious projects. The framework-agnostic nature means you can drop it into a Svelte, Vue, React, or even vanilla JS project without learning a new paradigm. The 'AI Powered' angle is interesting but doesn't affect your day-to-day use; it's more of a development process note. The modular plugin system is a plus if you want to extend behavior without bloating the core. However, there are gaps: no built-in accessibility features, no SSR documentation, and no advanced modal patterns like nested modals or complex animations. For most production apps, you might find yourself adding a lot of custom code on top. Compared to alternatives like Headless UI or Radix, Panes trades accessibility and framework integration for simplicity and size. If you love the iOS aesthetic and want a quick, dependency-free solution, it's worth trying. But for serious enterprise UI, you'll likely outgrow it.

Real-world workflow fit
Concrete scenarios for the personas Panes actually fits — and what changes day-one when you adopt it.
Adding a bottom sheet to a Svelte app
Outcome: Install Panes, import it, and create a Cupertino-style sheet with a few lines of code, enjoying smooth animations without pulling in a large UI framework.
Prototyping a modal card system
Outcome: Use Panes to quickly build modals with zero dependencies, keeping the prototype lightweight while still getting a polished iOS-like feel.
Replacing a jQuery modal
Outcome: Switch from a heavy jQuery plugin to Panes for a lighter, more modern implementation, reducing page weight and improving load times.
Use Cases
- Add Cupertino-style bottom sheets to a Svelte app that works seamlessly across browsers.
- Create a modal card system for a Vue dashboard without importing heavy UI frameworks.
- Quickly prototype floating panels for a React prototype using zero dependencies.
- Replace an existing jQuery modal solution with a modern, lightweight library.
- Build a bulletin-style notification pane for an Angular e-commerce site.
Limitations
- Panes is a lightweight, framework-agnostic UI library for creating Cupertino-style modals, cards, and panes.
- It is engineered using AI tools for refactoring and supervision, but it does not provide an underlying AI model for inference or generation.
- The library is modular, free, and has no third-party dependencies, with a 12KB gzipped bundle.
- Advanced features such as accessibility or server-side rendering are not explicitly documented in the evidence.

Where the pricing makes sense
The company stage and team size where Panes's pricing actually pencils out — and where peers do it cheaper.
Panes is free and open-source, so there's no cost barrier—unlike commercial modal libraries or headless UI kits that charge for extended support. It's ideal for indie developers and small teams who want a performant, dependency-free solution without spending money, but you might need to invest time in adding accessibility features yourself.
Setup time & first value
How long it actually takes to get something useful out of Panes — broken out by persona, not the marketing-page minute.
For a vanilla JS project, you can have a working pane in under 5 minutes. For framework integration (e.g., Svelte or React), expect 10-15 minutes to understand the API and integrate it properly.
Switching to or from Panes

- →From jQuery UI modals: Replace jQuery modal calls with Panes' simple API for a lighter, more modern solution.
- ↗To Headless UI or Radix: If you need better accessibility or framework-native behavior, you can swap out Panes for a headless component library, though you'll need to restructure your modal logic.

Featured Head-to-Head Comparisons
Panes vs Bito
Choose Bito if your team relies on AI coding agents across multiple repos and needs system-wide context for scoping, impact analysis, and production issue triage. Choose Panes if you need a free, ultra-light modal/pane library that works across frameworks with zero dependencies. They address completely different needs.
Panes vs Cognition Ai
For enterprises needing an autonomous engineer to write and ship production code—with $10M guarantees—Cognition AI’s Devin is unmatched. But if you just need a lightweight, free modal library, Panes is a zero-dependency winner. Choose the tool that fits your job: end-to-end automation vs. a single UI component.
Panes vs Poolside Ai
Poolside AI and Panes serve completely different needs. Poolside AI is a heavy-duty enterprise platform for deploying AI agents in high-consequence software engineering, while Panes is a free, lightweight UI library for modals and panes. Choose Poolside AI if you have enterprise budget and need secure, auditable AI for complex coding tasks; otherwise Panes is excellent for quick, cross-framework modals at zero cost.
