Comparison
Sentry vs LogRocket vs PostHog for a vibe-coded app
Short answer. Add Sentry or PostHog's error tracking when you need the stack trace. Add PostHog or LogRocket when you need to watch the session that led to it. LogRocket's current pricing page bills by sessions and does not list a free-forever plan. PostHog's free allowances reset every month, and usage past them is dropped until you add a card.
A Lovable, Bolt, Cursor, v0, or Replit app usually fails after someone other than you clicks through it. These three products are the ones people bolt on that afternoon. LogRocket is not a directory listing. Its column links to LogRocket's pricing page. Figures were read on 21 Oct 2026.

| Question | Sentry | LogRocket | PostHog |
|---|---|---|---|
| What you turn on first | Error monitoring and tracing. The Developer plan includes both, plus email alerts. Session replay is also on the pricing table, at 50 replays on the plans that list that row. | Session replay, product analytics, and error monitoring. LogRocket's pricing page says all of those products are included, and that analytics events, error events, and logs are unlimited. | Product analytics, session replay, and error tracking are separate products with separate free allowances. Feature flags are a fourth, with 1 million requests a month free. |
| Free or starting price | Developer is free for one user and includes 5,000 errors a month and 10 million spans. Team is listed at $26 a month when billed annually with the default prepaid data, with unlimited users and 50,000 errors included. Business is listed at $80 a month. New accounts get a 14-day trial, then stay on Developer if you do not upgrade. | The pricing page bills by monthly web and mobile sessions. At 25,000 sessions it showed a starting price of $176, and it says the final price depends on seats, retention, and add-ons. Core is the plan for under 100,000 sessions a month. Pro is a higher price below that volume and is the selected plan at 100,000 sessions and above. | Free is not a trial and does not need a card. Every month you get 1 million analytics events, 5,000 web recordings, 2,500 mobile recordings, and 100,000 error-tracking exceptions. The free plan is 1 project, unlimited members, and 1 year of data retention. Pay-as-you-go keeps those allowances and adds 6 projects and 7 years of retention. |
| What happens at the cap | On a paid plan you can set a pay-as-you-go budget. Sentry's docs say data past the reserved volume and that budget is dropped, and you are not charged for the dropped data. Developer has to move to Team or Business to raise the error quota. | You are paying for the session volume you configure. Analytics, errors, and logs are described as unlimited on every plan, so the meter LogRocket publishes is sessions, not events. | On the free plan, extra events are dropped and feature flags return a quota-limited response. On pay-as-you-go, usage above the free allowance is billed, and you can set a billing limit. The first paid analytics events start at $0.00005 each. Web recordings past 5,000 start at $0.005 each. |
| The privacy catch on a generated app | The browser DSN is expected to be public. An auth token used to upload source maps is not. Scrub passwords and tokens out of the context the SDK records, or the error report becomes a second copy of the leak. | LogRocket's session-replay page says you can mask sensitive fields so they are not shown in the replay or stored. Turn that on before the replay includes a settings screen, a key, or another person's data. | PostHog's directory notes say the same for its replay: mask inputs before production. A debug loop that sends an event on every keystroke also spends the free analytics allowance. |
| Fit for the first week | You want the exception and the stack trace, and one person can live inside the free Developer quota of 5,000 errors. | You want pixel-level replay and product analytics together, and you can pay from the first session package. There is no $0 row on the current pricing page. | You want analytics, replay, and errors without a card, inside the monthly allowances, and you are fine with one project on the free plan. |
Lean toward Sentry when
The app throws and you need the stack trace in email before you care about funnels. Stay on Developer while the volume is under 5,000 errors and you are the only user in the account.
Lean toward LogRocket when
Watching the session is the product you want, including heatmaps and funnels, and a session-based bill is acceptable. Read the seat and retention add-ons before you treat $176 as the whole price.
Lean toward PostHog when
You want one vendor for analytics, replay, flags, and errors, and the free monthly allowances cover a new app. Add a card only when you need a second project, longer retention, or volume past those allowances.
Sentry is the narrow error tool with a real free tier for one person. PostHog is the wide free tier across several products. LogRocket sells the replay and the analytics on a session meter. Whichever you install, mask the screen before a real user types a secret into it. The host and the database rules are separate problems.

FAQ
Is the Sentry DSN a secret?
No. Sentry's browser SDK is built to ship a DSN in the client. Treat source-map upload tokens as secrets. A public DSN can be used to send events to your project, so set the quota and avoid putting passwords or API keys in the extra data you attach.
Does LogRocket have a free plan?
The pricing page at logrocket.com on 21 Oct 2026 does not list a free-forever tier. It prices Core and Pro from the number of sessions you capture. At 25,000 sessions a month the page showed a starting price of $176 and said the final price depends on seats, retention, and add-ons.
What does PostHog include before you add a card?
PostHog's pricing page says the free tier needs no card and is not a trial. Each month it includes 1 million analytics events, 5,000 web recordings, 2,500 mobile recordings, and 100,000 exceptions. You get one project and one year of retention. Usage past the allowance is dropped on that plan.
Can I install these from Lovable, Bolt, or Cursor?
Yes, as an SDK or snippet in the project. Sentry and PostHog have directory pages because that install is common. LogRocket is the same kind of snippet and is compared here from its public pricing page. The install does not fix an open database table.
