PostHog and Sentry
PostHog started as product analytics and Sentry as error tracking. Each now does some of the other’s job. Here is where each one wins.
Pick Sentry for depth on errors
If errors and performance are the whole job, Sentry does more of it than PostHog or Vinktar.
Tracing, profiling and session replay
Sentry has all three, along with cron monitors, uptime monitors and release health.
SDKs for over a hundred platforms
Sentry maintains an official SDK for almost anything you run, mobile included.
SOC 2 and an EU region
Both, and years of track record behind them.
Errors in your coding agent
Sentry’s MCP server is free to use, and its agent plugin sets Sentry up from a prompt in Claude Code, Cursor or Codex.
Pick PostHog for the product around them
If you want to see what people do in your app, and the errors are one part of that, start with PostHog.
Everything around the error
Product analytics, session replay, feature flags, experiments and surveys live in the same place as your errors.
A large free plan
It covers errors, replay, flags and surveys. If your product fits inside it, use it.
A setup wizard
It scans your codebase, installs PostHog, creates events from your real product flows and builds dashboards.
A lower rate for anonymous traffic
Anonymous events cost less than identified ones. If most visitors never log in, the bill stays small.
Running both
Plenty of teams do: PostHog for analytics and replay, Sentry for errors. You get the best of each, with two SDKs, two bills and two places to look when something breaks.
Or one smaller tool for both
Vinktar does error tracking and product analytics on the same users, for a flat price. It does less than either of them, on purpose.
One SDK, the same users
Trends, funnels, retention and SQL run over the same people your errors come from. Who hit this error, and did they still check out, is one query.
A flat price, two budgets
Every plan is one price a month. Errors and events are counted separately, so a bad week of errors never uses up your analytics, and there is never an overage invoice.
Your agent sets it up
Over MCP, Claude Code, Cursor or Codex installs the SDK, writes down what each event means and reads your errors and events back. Agent access is on every plan, with no charge per call.
What it does not have
Session replay, feature flags, tracing and profiling. If you need any of them, one of the two above is the better pick.
Try it on your own errors
The free plan needs no card. The live demo is a real workspace with data in it.
