Umami is open-source, cookieless traffic analytics. You can self-host or use Umami Cloud, and track visits, set up funnels, follow paths and referrers, and see how traffic breaks down. When it runs on your infra, you keep the data.
Oculis Analytics is revenue attribution analytics: which channels bring paying customers and how much revenue each drives.
Umami is centered around traffic and web analytics insights; Oculis Analytics' sole focus is to show which marketing channels bring paying customers, so you can use this data to scale your business.
What Umami is good for
Umami is a good choice if you want an open source tool to see your traffic data without a complex Google Analytics setup. It shines when your main questions are who came to your site and how they found you.
Where it stands out:
- Open source and ownable: released under the MIT license, so you can self-host and keep your data on your own infrastructure
- Cookieless by design: tracking without cookies means you can often skip the consent banner and stay GDPR and CCPA friendly
- Lightweight: a small tracking script that won't weigh your pages down
- Clean and readable: visits, referrers, top pages, and paths in one simple dashboard, no analytics degree required
When you need revenue by channel
Umami's focus is web analytics (traffic, visits, how people move through your site), not revenue attribution. If you need revenue by marketing channel, that is a different category of tool.
Here is where the gap shows up. Say Umami reports that a Reddit thread sent you 4,000 visits last month and your newsletter sent 400. Traffic says Reddit won by a mile. But if those 400 newsletter readers included 30 paying customers and Reddit produced 2, the newsletter is the channel actually funding the business.
A traffic-first tool can't close that loop on its own. You would export the numbers, match them against your payment provider by hand, and rebuild the picture in a spreadsheet every month. That is the work Oculis Analytics does for you.
What Oculis Analytics does
Oculis Analytics is revenue attribution analytics by channel. The question it answers is which marketing sources drive paying customers and revenue, not only traffic.
You'll get:
- A lightweight setup: add the tracking script to your site, then connect your payment provider
- A clear read on where paying customers come from, so your strategy is based around ROI, not page view data
- Subscriber retention by cohort: see how many paying customers stick around month over month, based on actual payment data, not just return visits
- Visits, signups, and payments connected so you can see which channels work for your business specifically
It goes beyond tracking visits only: paying users and page views live in one product, so you get marketing revenue attribution you can use to scale your business instead of treating payments and traffic as two separate stories.
Pick Umami if
- Traffic data + privacy + data ownership matter most
- You want cheap or self-hosted traffic analytics, not channel ROI
Pick Oculis Analytics if
- Growing revenue is central to your strategy and you want to see which channels drive it, without building that view yourself
- Paying users, page views, and sources in one product, not two tools that never match.
- You need ROI by channel, not page view spikes.
Pricing
If you only need traffic numbers, Umami's free tier is the cheaper option. Oculis also starts free, and paid plans begin at $5/month, so you're paying for revenue tied to channels and a hosted service with nothing to run yourself. Pick the one that matches whether you care more about lowest cost or about marketing ROI.
