When you would pay

The free allowance is large enough to build on properly. Upgrade when you consistently hit the ceiling — not before, and not because a banner suggests it.

The free plan in practice

What you can actually do on Sentry's free plan (Developer plan free with 5k errors/month), where it stops, and when it's worth paying.

When to upgrade to a paid plan

Stay on the free plan while you're comfortably under the free plan's limit (Developer plan free with 5k errors/month). It's worth moving to a paid plan once you consistently bump into that ceiling, need to remove branding, or want features the free tier holds back.
