[5.0.0] - 2025-03-06

Ark UI just got a major performance boost! 🚀

What’s new in v5?

  • Blazing-fast performance – Every component runs smoother and renders faster.
  • Smaller bundle size – Leaner components and adapters for a more efficient build.

We made this happen by using React’s native reactive primitives instead of external stores.

In our stress tests with 10,000 components, Ark v5 delivered 1.5x–4x better performance across the board.

Performance comparison showing Ark v5 is 1.5x-4x faster than other libraries

A quick note on tests

Most component updates are non-breaking, but due to this change, some tests may need adjustments. For example:

// Before
it('should open by default', () => {
  render(<ComponentUnderTest defaultOpen />)
  expect(screen.getByRole('dialog')).toBeInTheDocument()
})

// After
it('should open by default', async () => {
  render(<ComponentUnderTest defaultOpen />)
  expect(await screen.findByRole('dialog')).toBeInTheDocument()
})
