01/The verdict
Web analytics that ties traffic sources to Stripe, LemonSqueezy, Polar, Shopify and Paddle revenue. Indie founders and small SaaS teams pay from $9/month.
The product itself is a known pattern: a 4KB tracking script, a Plausible-style dashboard and revenue attribution through payment-provider APIs. Clones like Faurya, DataBull, Minilytics and Flowsery already exist, and Marc Lou calls analytics a crowded vitamin market. What protects it is distribution no clone can buy. It has Marc Lou's 417k X followers and roughly 140k YouTube subscribers, it is the built-in analytics recommended in ShipFast, and it is one of only three traffic-verification sources on TrustMRR, which Marc also owns. Customers can still leave easily, so it lands in the middle of the real tier.

Deep
Marc Lou has about 417k X followers and around 140k YouTube subscribers, and he builds in public. DataFast launched on X and grew through his posts, his newsletter and shareable screenshots.
To cross it: Build an indie-hacker audience of hundreds of thousands, which time and money alone rarely buy.
Real
The ShipFast docs tell every boilerplate buyer to paste the DataFast script, with 30% off. TrustMRR, Marc's verified-revenue site, lists DataFast next to Google Analytics and Search Console as a traffic source. There is also a 50% recurring affiliate program.
To cross it: Own or partner with a popular boilerplate or founder directory that pushes your script by default.
Real
datafa.st has a domain rating of 73 and publishes comparison and alternatives pages against Plausible and others. Review and roundup sites also cover it widely.
To cross it: Spend 12 to 24 months on comparison content and backlinks to rank for searches like 'revenue analytics' and 'Plausible alternative'.
Shallow
Revenue attribution works with Stripe, LemonSqueezy, Polar, Shopify, WooCommerce, Paddle and Dodo Payments. There are also an API, an iOS app and a cookieless mode, and it has handled over 1 billion pageviews.
To cross it: Ship the same payment connectors and handle bot traffic at scale, which takes a couple of months with AI tools.
03/The gap
Easy to copy
- The dashboard, real-time visitor map and revenue-by-channel charts are standard and easy to copy
- Each payment connector is a public OAuth or webhook integration
- The $9/month price is easy to undercut, and a free or $29 lifetime clone already showed up within hours
- Leaving is just swapping one script tag, and only some historical data is lost
How you'd go after it
- Sell a lifetime deal or self-hosted open-source version to price-sensitive indie hackers who dislike subscriptions
- Go after keyword-level and Search Console revenue attribution, which reviewers say DataFast lacks
- Serve agencies and ecommerce brands outside Marc's indie audience, with ad-platform conversion syncing like Cometly
- Build cookieless, EU-hosted analytics with revenue built in for GDPR-sensitive European teams
04/Build against it?
Only with an edge
Only go in with your own distribution or a clear niche, such as keyword revenue attribution, agencies or ecommerce. Inside the indie-hacker crowd you are fighting Marc Lou's audience and his ecosystem.

- Marc Lou on X: "One year later... 🎉 DataFast tracked 1 billion pageviews 🎉 This SaaS is the hardest thing I've built. The industry is ultra-competitive, analytics are vitamin products, and now there's a swarm of scrappers to train LLMs, it sucks all my time. But it makes my days exciting! https://t.co/KQWnxPdr3q" / X
- Marc Lou on X: "It took 512 days. This is the hardest thing I’ve done. The analytics market is ultra-competitive, and users perceive data as a vitamin, not painkillers. It took 9 months to grow DataFast to $3k MRR. It was so slow, I thought about giving up many times in the first year. I tried a million things, but these 3 really moved the needle: - I built DataFast for me. I forced myself to ask: “What do I really need?” That’s how the analytics + Stripe angle came up. In other words, I niched down. - I polished the onboarding like a madman once I realized 90% of people who signed up didn’t do anything. Fewer steps, faster AHA moment. You’re a drug dealer, and your users are craving. Give them dopamine ASAP. - I built shareable features. I added 𝕏 mentions on top of the traffic chart, built a real-time map, created a stock market app for analytics, and more. My customers did marketing for me. All I had to do was give them a reason to. The hardest part really is the beginning. Once momentum picks up, you’ve already done the hardest part. For perspective, I'm adding more MRR in 4 weeks than I did in 4 months. I don’t know what’s next, but I like challenging myself, so... See you at $1M ARR 🫡" / X
