TopStats as a PostHog alternative
PostHog is a broad, open-source product suite. TopStats is narrower on purpose: a focused analytics layer for the events your backend, Discord bot and game servers emit, with first-class OpenTelemetry ingestion and a full white-label option (your own domain, logo and colours) that PostHog does not offer.
TopStats vs Mixpanel for backend events
Mixpanel is built around web and mobile product analytics. TopStats ingests server-side events over plain HTTP, OpenTelemetry or an SDK, keeps funnels and retention on every plan, and adds dedicated Discord bot analytics, all on self-serve, flat pricing.
A self-serve Amplitude alternative
Amplitude matches TopStats on a generous free tier, but its Growth and Enterprise plans are quote-based and sales-led. TopStats stays self-serve at every tier, so you can start and scale without booking a call.
TopStats vs Plausible for server-side events
Plausible is excellent at what it aims to be: lightweight, privacy-first WEB analytics - a script tag counting pageviews and goals. TopStats starts where the script tag ends: events from your backend, Discord bot or game server, with actors, funnels, retention, feature flags and alerts. If you need to know what happened inside your product rather than on your marketing site, Plausible has no answer to send the event from a Minecraft plugin or a Fastify API - TopStats ships those integrations out of the box. Many teams run both: Plausible on the website, TopStats on the product.
TopStats vs Fathom for product analytics
Fathom, like Plausible, is privacy-focused website analytics: simple, GDPR-friendly, pageview-centric. It does not model actors, sessions on a game server, funnels across API events, or feature flags. TopStats is built for exactly that server-side surface, with flat volume-based pricing in the same self-serve spirit - free to 2M events a month, then one predictable number for events and retention, never per-seat.
