SupaStory vs Sentry

What Does Sentry Really Cost?

Sentry is the industry standard for error tracking, and for good reason. It is excellent at catching crashes, exceptions, and performance issues. But Sentry's pricing gets complicated once you add session replay and their new AI capabilities.

The base pricing looks straightforward: the Team plan starts at $26/mo and Business at $80/mo. Both include 500 session replays per month. The free Developer plan gives you 50 replays.

Here is where it gets expensive: Sentry's Seer AI Agent, which handles AI debugging, root cause analysis, code fix generation, and PR creation, costs an additional $40 per active contributor per month. That is on top of your base plan.

The True Cost for a Small Team

Let's do the math. A 3-person development team on Sentry's Team plan with Seer AI enabled pays:

• Sentry Team: $26/mo
• Seer AI: 3 contributors x $40/mo = $120/mo
• Total: $146/mo

For that $146/mo, you get 500 capped session replays and AI-powered debugging. Once you hit 500 replays, new sessions are simply dropped. Data gone.

SupaStory's Startup plan costs $149/mo and includes unlimited session replays, 1,000 AI-analyzed sessions, automatic code fixes, GitHub PRs, and conversion impact estimates. Unlimited team members. No per-seat charges.

Error Monitoring vs UX Monitoring

This is the core distinction. Sentry is built around errors. It excels at catching JavaScript exceptions, tracking performance regressions, and helping you debug stack traces. If your primary need is error monitoring, Sentry is hard to beat.

But not every UX problem throws an error. A confusing form layout, a button that is hard to find on mobile, a checkout flow that asks for too much information, these are conversion killers that Sentry will never detect because they are not errors. They are design and UX problems.

SupaStory is built around UX. Our AI analyzes user behavior, not just error logs. It detects frustration patterns, identifies conversion blockers, and estimates the revenue impact of each issue. When there is a code fix available, it generates one and opens a PR.

Session Replay: 500 Cap vs Unlimited

Sentry caps session replays at 500 per month on both Team and Business plans. Once you reach 500, sessions stop being captured. If an important user encounters a bug in session 501, you will never know about it.

SupaStory never stops capturing sessions. Every plan includes unlimited replays. When you hit your AI analysis quota, the recordings continue. Your AI analysis pauses until the next billing cycle, but you never lose session data.

Should You Replace Sentry with SupaStory?

Not necessarily. They solve different problems. If you need deep error monitoring with stack traces, performance monitoring, and broad language/framework support, keep Sentry. It is great at what it does.

But if you are adding Sentry primarily for session replay and AI-powered fixes, SupaStory gives you more for less. You get unlimited replays instead of 500, AI analysis included instead of $40 per developer, and conversion impact estimates that Sentry does not offer.

Many teams run both: Sentry for error monitoring and SupaStory for UX optimization. They complement each other well.

The Bottom Line

Sentry is an outstanding error monitoring tool. But its session replay is capped, its AI costs extra per developer, and it was not designed to find UX issues or estimate conversion impact. If you are looking for session replay with AI-powered UX analysis, SupaStory delivers more value at a comparable price point.
