Is Traceloop worth the price?
Traceloop's pricing is very generous, offering a substantial 'Free Forever' tier with up to 50K spans and 5 seats.
This makes it highly accessible for small teams and individual developers. The lack of a transparent mid-tier option means larger growing teams will quickly hit a 'Contact Us' wall, which can be a deterrent.
It's best for small teams and startups looking to get started with LLM application monitoring without upfront costs.
