Best forBroad SDK coverage across languages and frameworks, with performance tracing next to errors.

PostHog alternatives
Not a ranking: each option is described by the situation it fits, with its trade-off, whether it's open source or free to start, whether AI coding agents can work with it, and how many makers' products use it for this job.

For error monitoring
The whole decision →Hosted service or self-hosted tracker. Hosted services give you setup in minutes and pricing by event volume; self-hosting keeps error data on your servers for the cost of running and upgrading it.
PostHog (Hosted service): Error tracking in the same tool as your product analytics and session replays, so an exception links to what the user did. Trade-off: Younger than dedicated trackers, with fewer SDKs and alerting options.
Best forError grouping tied to releases, with session replays linked to errors.
Trade-offSmaller ecosystem of integrations and guides than Sentry.

Highlight
Self-hosted trackerOpen sourcellms.txt
Best forSelf-hosting errors, session replays, logs and traces from the open-source code of a product that no longer runs as a hosted service.
Trade-offThe hosted service shut down in February 2026 after LaunchDarkly bought it, so the self-hosted code has little ongoing development to rely on.
Used by 2 makers' products for this
Best forOne tool covering errors, logs, uptime checks and cron monitoring, with a free plan for a single developer.
Trade-offFewer language SDKs and less depth in tracing than larger platforms.

For product analytics
The whole decision →All-in-one platform or dedicated analytics tool. All-in-one platforms put event analytics next to session replay, feature flags and experiments, billed per product. Dedicated tools go deeper on funnels, retention and cohorts, with replay and flags added around them. Every option needs events wired into your code.
PostHog (All-in-one platform): One tool for analytics, session replay, feature flags, experiments and surveys, each with its own free monthly allowance. Trade-off: Events tied to identified users cost several times more than anonymous ones past the free million; many products in one UI take time to learn.
Best forMature funnel, retention and cohort analysis on event data.
Trade-offThe free plan stops at 1 million events and 5 saved reports per user; group analytics and data pipelines are paid add-ons.

For web analytics
The whole decision →Cookie-free dashboard or full marketing suite. Cookie-free tools show pageviews, referrers, UTM campaigns and simple goals on one page and usually need no consent banner. Google Analytics is free and goes much deeper into campaigns and ads, but sets cookies, so EU visitors need a consent banner and some of them are never counted.
PostHog (Part of product analytics): A web analytics dashboard in the same tool as funnels, session replays and feature flags. Trade-off: Pageviews count as product analytics events, so a busy marketing site uses up the free allowance you may want for in-app events.
