Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bolt.new

  • The free plan is capped at 300K tokens a day and 1M tokens a month
  • Pro starts at 10M tokens a month for $25, so heavy sessions are metered rather than unlimited
  • Team seats are billed at $30 per member per month and tokens are not pooled across the team
  • Unused tokens roll over for one additional month only, so they expire after two

Radix UI

  • You write all the styling, so time to a finished interface is much longer than with a styled library
  • Composable part-based APIs are more verbose than a single component with props
  • Covers primitives rather than complex widgets, so data grids and date pickers come from elsewhere

Answered from the vendors’ own pages

Bolt.new: Can I use Bolt for free indefinitely?

Bolt invites users to 'Try it out and start building for free', indicating a free option is available. However, the page mentions two tiers (Standard and MaxPro) and includes a '/pricing' link, suggesting paid plans exist. Specific details about free tier limits and paid pricing are not on the main page.

Source
Radix UI: Is Radix UI free?

Yes, open source under the MIT licence.

Bolt.new: What are the differences between Standard and MaxPro tiers?

The page mentions both 'Standard' (described as 'Recommended for general development') and 'MaxPro' tiers in feature comparisons, but does not disclose specific differences, pricing, or what qualifies as 'general development' vs. other use cases.

Source
Radix UI: Why use unstyled components?

Because accessibility is the hard part and visual design is the part teams want to own. Radix gives the first and stays out of the second.

Bolt.new: Are there usage limits on the free tier?

The page does not specify what limits apply to the free tier. To obtain detailed information about free tier limits and paid plan features, you would need to visit the dedicated pricing page.
