What is the best open-source alternative to Plausible?

It depends on what you want to change. If you want revenue by source, trckable and some of the other tools handle it differently: see trckable vs Plausible and the revenue column above. If you want the same kind of hosted simplicity, the comparison pages say what each tool offers.

Is Plausible open source?

Its self-hosted edition and tracker are open source, under the licences in the table, and its self-hosted Community Edition leaves out some features the cloud service has. The table cites its own pages on both points.

Is Umami open source?

Yes: its repository carries the MIT licence, per the table. Some features, such as email reports, are available on its cloud service only.

Can I self-host Matomo, PostHog or Pirsch?

Matomo's On-Premise Community edition is free. PostHog offers a free Docker Compose deployment, which its docs describe as unsupported. Pirsch requires a paid Enterprise licence to self-host. The self-hosting table above has the wording and the sources.

Which open-source tool is smallest to run?

Compare the requirements in the self-hosting table with the script sizes in the main table. trckable is one container with no external database, and its idle memory and script size are CI's measurements, published on the benchmarks page.

Does open source make an analytics tool private?

Not by itself. Open source lets you read what the code does and run it yourself, which helps. Privacy still depends on what the tool collects and how you set it up. See the cookieless analytics guide.

Open-source analytics alternatives

Seven open-source analytics tools, set side by side, with where each is strong and what to check before you pick one. Every fact about another tool is cited to its own pages.

In short

Open source does not mean the same thing everywhere. Some tools hold features back from the self-hosted edition, some need a paid licence to self-host, and some are only partly open.
The table has the licence, self-hosting, price, revenue handling, cookies and script size of each tool, from its own pages, checked on 2 October 2026.
Not sure what you need? The decision guide below starts from what you want to do, not from a ranking.

Seven open-source tools side by side#

Tool	Cheapest plan at 100k a month	Revenue by source	Self-hosting	Licence	Cookies	Script, gzipped
trckablethis site	$6 a month, $60 a year	Yes: sales credited to the visit that earned them	Yes, free, every feature	Server AGPL-3.0, tracker and npm package MIT	None in cookieless mode; one first-party cookie otherwise	2,045 B

Prices are in US dollars, for the cheapest plan that covers 100,000 events, pageviews or hits a month, in each tool's own counting unit. Our own price is on the home page's pricing. "Not stated" means the tool's pages do not say. The script column is gzipped bytes: what the other tools' servers send, as measured on 2 October 2026, and what our CI measures for trckable (1 Oct 2026).

What "open source" means when you want to self-host#

Four questions decide whether open source helps you.

Which licence, and for which part? MIT and similar permissive licences let anyone use the code with almost no conditions. AGPL-3.0 and GPL v3 are copyleft licences: changes you distribute (with AGPL, also changes you offer as a service) must be shared under the same licence. A tool can use one licence for its server and another for the script on your pages.

Is the self-hosted edition the whole product? Some tools offer a self-hosted edition with fewer features than their cloud service. Others self-host the same program they sell. The table below says what each tool's own pages say.

What does it cost to self-host? Free software is not free to run: there is the server, the database it needs, the backups and the upgrades. A tool that needs a separate analytics database tends to cost more to run than one that does not.

Is self-hosting supported? Self-hosting may be free but unsupported, or require a paid licence. That affects what you can count on when something breaks.

Tool	Self-hosting	Open source
trckable	Yes, free: the same program that runs our Cloud	Yes: server AGPL-3.0, tracker and npm package MIT
Plausible	Yes, free: Community Edition on your own server, released twice a year, without funnels, user journeys, revenue goals, SSO and the Sites API⁴	Yes: the self-hosted edition is AGPL-3.0 or later; the tracker you embed is MIT^{4, 9}
Umami	Yes, free, with Node.js and PostgreSQL, from source or Docker; some features, such as email reports, are Cloud only^{1, 5}	Yes: MIT licence, per the LICENSE file in its repo⁶
Matomo	Yes: the On-Premise Community edition is free, with unlimited users and hits¹	Yes: GPL v3 or later³
PostHog	Yes: a free Docker Compose deploy; its docs call self-hosted setups officially unsupported⁸	Yes: MIT for most of the code; the ee folder has its own licence⁷
Swetrix	Yes, free: a Community Edition you run with Docker^{1, 3}	Yes: AGPL-3.0, per the licence file in its repo⁴
Pirsch	Yes, with a paid Enterprise License, priced by your size and needs⁴	Yes, the core: AGPL-3.0, per the licence file in its repo⁵

Where each tool is strong#

Taken from each tool's own pages. Each name links to a full comparison with trckable.

trckable

Free and open source (server AGPL-3.0, tracker and npm package MIT). One container with no external database, using 52 MB of memory when idle by CI's measurement, and a browser script of 2,045 bytes gzipped with goals, outbound links and checkout attribution. Every feature is in the self-hosted program, which is the one that runs trckable Cloud. Its focus is revenue: payments from Stripe, Paddle, Lemon Squeezy, Polar and Dodo are credited to the visit that earned them. See revenue attribution.

Plausible

A hosted, EU-based analytics service with four plans priced by monthly traffic; it also has a self-hosted edition.

Funnels, user journeys, a Data Studio connector and Google Analytics import are listed on its plans¹.
Teams can be split per client, each with its own subscription and billing¹⁰.

Umami

Open-source web analytics you can self-host for free or use as a paid cloud service, billed by events.

Its Business plan adds session replays and heatmaps, and its Hobby plan is free up to 100K events a month¹.
Its whole app is MIT-licensed, a more permissive licence than our AGPL-3.0 server, and it has a hosted plan for people who do not want to run it^{1, 5, 6}.

Matomo

An open-source analytics platform you can host yourself for free (On-Premise) or pay Matomo to host (Cloud).

Heatmaps and session recording, A/B testing, funnels and a tag manager are listed on its plans, and it can import data from Google Analytics¹.
It can export raw data to a data warehouse, and reports in CSV, TSV, XML or JSON⁷.

PostHog

PostHog's Web analytics product: a traffic dashboard in an open-source suite, billed per event after 1M free a month.

Session replay, feature flags, experiments and surveys come from the same sign-up, each with its own free monthly allowance¹.
The free plan covers 1M events a month with unlimited team members, and it is open source under MIT for most of the code^{1, 7}.

Swetrix

Open-source, cookieless web analytics with error tracking, session replays and experiments, on a paid cloud or self-hosted.

Error tracking, performance monitoring and funnels are in both paid plans, and Plus adds session replays, feature flags and A/B testing¹.
It has an Ask AI tab that answers questions about your data, included in every plan^{1, 7}.

Pirsch

A German-hosted, cookie-free web analytics service with an open-source core, billed by page views.

Its plans keep unlimited data and unlimited members, and it imports history from Google Analytics, Plausible and Fathom¹.
It has a built-in URL shortener and A/B testing with segmentation on its Plus plan¹.

Tools that do not say they are open source#

These come up in the same searches, so here they are, with the same facts. For Fathom, only an older version, Fathom Lite, is open. A hosted tool can be the right answer if you would rather not run anything.

Tool	Cheapest plan at 100k a month	Revenue by source	Self-hosting	Licence	Cookies	Script, gzipped
trckablethis site	$6 a month, $60 a year	Yes: sales credited to the visit that earned them	Yes, free, every feature	Server AGPL-3.0, tracker and npm package MIT	None in cookieless mode; one first-party cookie otherwise	2,045 B
DataFastevents	Starter $19 a month, $190 a year¹	Yes, by marketing channel²	Not stated	Not stated	Cookies by default; a cookieless script is less accurate for long-term attribution⁵	5,253 B
Fathom Analyticspageviews	$15 a month, $150 a year¹	Event values; a revenue-by-source report is not stated^{2, 3}	Only the older Fathom Lite^{6, 13}	Fathom Lite MIT; the current product is not stated⁶	None⁸	2,090 B
Simple Analyticspageviews	Simple $20 a month, $200 a year¹	Not stated	No²	Not open source²	None⁴	3,884 B
Google Analytics 4events	$0: Google Analytics is free of charge¹	Yes, in the traffic acquisition report⁴	Not stated	Not stated	First-party cookies (_ga), 2 years by default⁵	155,016 B

DataFast

A hosted analytics tool built around one question: which marketing channel brought the revenue.

Shopify connects for revenue, and it adds social mentions from X and Reddit on its Growth plan^{1, 2}.
It is a hosted service with nothing to run, which suits people who do not want a server¹.

Fathom Analytics

A hosted, cookie-free analytics service from a Canadian company, with one feature set on every plan and prices set by monthly traffic.

Every plan includes at least 50 sites, and extra sites come in packs of 50¹.
It lists a Google Search Console integration and a Google Analytics importer among its features¹².

Simple Analytics

A hosted analytics service from a Dutch company, with a free plan, a traffic-priced paid plan and custom Enterprise deals.

You can pay in euros, dollars or pounds, by card, Apple Pay, Google Pay or Bitcoin¹.
It has a free plan for up to 5 websites, with 1 month of history¹.

Google Analytics 4

Google's free web and app analytics product, with a separate paid 360 tier that raises limits.

Standard properties cost nothing¹, and their raw events can be exported to BigQuery, up to 1M events a day, which can go to a free BigQuery sandbox⁹.
Ask Advisor, a Gemini-powered assistant, is built into the product (beta), and a read-only MCP server exists for your own AI tools^{7, 8}.

Which one should you pick?#

Start from the job, not from a ranking.

You want revenue by traffic source, on a small server. Look at the revenue column first. Some tools take an amount you send from your own code, some connect the payment provider, and some do neither. trckable's focus is the second, with five providers. Revenue attribution explains how it works.
You want a hosted service and no server. A hosted service is the easiest start, and several tools above offer one. Compare the price at your traffic, not at 100,000 events, on each tool's page.
You want the widest toolbox. Matomo and PostHog list more than web analytics: heatmaps, session recording, A/B testing and more, from their own pages. If you need those, a web analytics tool is not the choice.
You want the simplest self-hosting. Compare what each tool needs to run, in the self-hosting table above, and what its self-hosted edition leaves out.
You want the most permissive licence. MIT is the most permissive in the table. Check the licence of the server and of the tracker separately.
You need no cookie banner in the EU. No tool can promise that for you. Several of these tools set no cookies by default. Read the cookieless analytics guide for what actually decides it.
You are moving from Google Analytics. A few of these import your history. trckable imports from Plausible, Umami and Google Analytics 4: see migrating.

How we check these facts#

Each fact comes from the tool's own pricing page, documentation or public repository, read on the date shown in the sources below. We write what we find in our own words, measure each script ourselves, and say "Not stated" where a tool's pages do not say. Prices and plans change, so check the tool's page before you buy. If something here is wrong, tell us and we will fix it.

Looking for one specific tool? The comparison pages go deeper, with price at three sizes and a longer list of rows: DataFast, Plausible, Umami, Matomo, PostHog, Swetrix, Pirsch, Fathom, Simple Analytics and Google Analytics 4. The full table of all eleven is on the compare page.
