The best PostHog alternatives. Honestly ranked.
Most people look past PostHog for one of two reasons: self-hosting it means running Kafka, ClickHouse, Redis, and Postgres, or the usage-based bill gets hard to predict once several products are switched on. Here's the honest shortlist and who each tool is actually right for.
Why people look for a PostHog alternative
- ·Self-hosting is a heavy lift: running it myself means Kafka, ClickHouse, Redis, and Postgres, and PostHog itself has written that many teams lack the resources to run it reliably.
- ·It's fragile to operate at the edges: a full disk has taken instances down for hours, so it's a stack to babysit, not one process to forget.
- ·The bill is hard to predict: usage-based pricing across events, recordings, flags, and surveys adds up in ways I can't budget at scale.
- ·The all-in-one breadth is overwhelming when all I actually want is product analytics: there's a lot to configure and learn for the slice I use.
- ·I want to own my data on something simple, or my cloud free tier ran out and the next step up felt like a jump.
PostHog alternatives worth switching to
Mixpanel
Free up to 1M events/mo; Growth event-based (~$0.28 per 1K events above); Enterprise custom-quoted (as of 2026)Managed product analytics, no cluster to run
Best for: Teams that want deep funnels, retention, and cohorts as a hosted product without operating Kafka + ClickHouse themselves
Tradeoff: Hosted-only (you don't own the data), and its 2026 event-based pricing climbs into the thousands per month past the free tier
Amplitude
Free Starter (~50K MTUs); Plus from ~$49/mo; Growth/Enterprise custom-quoted (as of 2026)The enterprise product-analytics rival
Best for: Growth and product teams that need the deepest behavioral cohorts and predictive/LTV analysis and are fine with enterprise pricing
Tradeoff: Powerful but usage-priced and sales-led on higher tiers, overkill for a solo dev or tiny team
smolanalyticsthis is us
Pro $49/mo (1M events), Scale $149/mo (10M); flat $8 per extra million; self-host free foreverOnly analytics, lighter, ask in your editor
Best for: Solo developers and small startups who want product + web analytics on one Go binary (no Kafka/ClickHouse), a verdict on what to fix, and answers over MCP on their own model, while owning their data
Tradeoff: Its session inspector is event-based, not pixel-perfect DOM session recording, keep PostHog if video-style replay is why you're on it
Matomo
Self-host free (open source); Cloud from ~$26/mo (as of 2026)Mature, self-hostable web-analytics suite
Best for: Teams that want a do-everything, self-hosted web-analytics platform with a long feature history and are fine running the stack
Tradeoff: Self-host is a PHP + MySQL install with an archive cron to operate; product-analytics depth is lighter than PostHog's
Plausible
Self-host free (open source); managed cloud from ~$9/mo (as of 2026)Lightweight, privacy-first web stats
Best for: Switchers who realize they only needed clean, cookieless website traffic numbers and want something tiny and private
Tradeoff: Web analytics only, funnels and user journeys are on the Business plan, and there are no retention cohorts
Umami
Self-host free (open source); Umami Cloud free tier + paid from ~$9/mo (as of 2026)Open-source, self-hostable web analytics
Best for: Developers who want a free, privacy-friendly, self-hosted web-analytics tool that's far lighter than PostHog
Tradeoff: Needs a Postgres or MySQL database beside it, and it's web-analytics-first (product features are newer)
Google Analytics 4 (GA4)
Free; GA4 360 enterprise custom-quoted (as of 2026)Free, event-based, web + app
Best for: Teams that want a free, ubiquitous analytics tool across web and app and can live inside Google's ecosystem
Tradeoff: Data sampling on large queries, a steep UI, and your data lives with Google; weaker for product workflows like retention and per-user paths
Who should pick what
- ·You need pixel-perfect DOM session replay or PostHog's deep experiment tooling, and the free tier covers you Keep PostHog, it does these deepest and is genuinely generous free; nothing here matches that depth
- ·You want deep product analytics as a managed service without running a cluster Mixpanel or Amplitude, hosted depth, at the cost of data ownership and (eventually) a bigger bill
- ·You're a solo dev or small startup who wants only analytics, lighter, and to ask your numbers in your editor smolanalytics, one Go binary, a verdict, $8 per extra million, own your data (flags, experiments, heatmaps, surveys and a session inspector; no pixel-perfect DOM replay)
- ·You realize you only ever needed clean, private web stats Plausible, Umami, or Fathom, cookieless and cheap, no cluster and no product-analytics weight
- ·You want a mature, self-hostable web suite and can run the stack Matomo, the long-standing PHP + MySQL option
- ·You want free and ubiquitous and can accept Google's tradeoffs GA4, free, but heavier and less product-focused than the rest
PostHog alternatives: FAQ
Is smolanalytics a good PostHog alternative?
Yes, if PostHog's weight is the problem and analytics is what you actually use it for. smolanalytics is a single MIT-licensed Go binary with no external services (no Kafka, ClickHouse, Redis, or Postgres): docker run and it's up in about 30 seconds. It does funnels, retention, paths, and cohorts, adds a daily verdict on what to fix, and lets your own Claude or Cursor answer questions over MCP on your own model, so there's no AI bill, and its answers come from the same deterministic reports the dashboard renders, with a CI test that fails the build if the two ever differ. It's also cheaper to scale: a flat $8 per extra million events versus PostHog's roughly $50, plus free unlimited self-host. It now does feature flags, experiments, heatmaps, surveys and an event-based session inspector too; the one thing it doesn't do is pixel-perfect DOM session recording, so keep PostHog if that's what you need.
Why do people look for a PostHog alternative?
Two honest reasons. First, self-host weight: running PostHog yourself means operating Kafka, ClickHouse, Redis, and Postgres, and PostHog itself has written that many teams lack the resources to run it reliably; a full disk can take an instance down for hours. Second, cost predictability: usage-based pricing across events, session recordings, feature flags, and surveys is hard to budget at scale. Teams that only want the analytics slice often find the all-in-one breadth is more than they need to configure and carry.
What's the lightest self-hosted PostHog alternative?
smolanalytics is the lightest: one static Go binary and one data file, no message queue, columnar cluster, or database to operate. Matomo is self-hostable too but is a PHP + MySQL install with an archive cron. Umami is lightweight but still needs a Postgres or MySQL database beside it. If the reason you're leaving PostHog is the operational weight, a single-binary tool removes it entirely, at the cost of PostHog's pixel-perfect DOM session replay and the depth of its bundled products.
What's the cheapest PostHog alternative?
Self-hosted open-source tools are free to run: smolanalytics, Matomo, Umami, and Plausible can all be self-hosted at no cost, and GA4's hosted tier is free. Among paid hosted options, smolanalytics is predictable at $49/mo for 1M events or $149/mo for 10M, with a flat $8 per extra million, versus the roughly $50-per-million overage typical of PostHog and Mixpanel. PostHog's own cloud free tier is generous, though, so if it covers your volume there may be no cost reason to switch at all.
Should I just stay on PostHog?
Often, yes. If PostHog's cloud free tier covers your volume and the self-host weight never bites you, there's no strong reason to move, and if you rely on pixel-perfect DOM session replay, PostHog does that and the alternatives here don't. Look at an alternative when the operational weight is real, the bill has become hard to predict, or you only use the analytics part and want something lighter you fully own.
