When free is enough
1 of these 3 debugging tools offer a free or freemium plan (Lightrun is the one we'd start with). Free tiers suit light or occasional use, testing a workflow, or personal projects — though they usually cap usage, features or output quality.
When to go paid
For heavy or professional debugging work, a paid plan like Sentry Seer's buys higher limits, team collaboration, priority support and advanced features. If a tool is core to your daily work, the subscription usually pays for itself in time saved.
