DataFast Alternatives in 2026: 8 Tools Ranked by the Job

The short answer: As of October 8, 2026, the best DataFast alternative depends on what you need beyond revenue by channel. Seline is the closest match on price and idea, from $9/month with Stripe, Polar and Shopify revenue. Plausible ($9/month for 10k pageviews) and Fathom ($15/month for 100k pageviews) are the pick for plain privacy analytics. PostHog is the free option for product teams, with 1M events a month free. Cometly and Usermaven cover multi-platform ad attribution, but both sell through a demo. Humblytics ($79/month) fits when you need A/B testing and heatmaps on the same revenue data, plus Google Ads and Meta spend in ROAS. If revenue by channel is the whole job, DataFast at $9/month is hard to beat.

DataFast is a good product at a low price. Most people who search for an alternative are not unhappy with it. They have hit the edge of what it does. They want to test a page, see where people click, pull in ad spend, or keep analytics free.

One more reason this guide exists. Search summaries currently repeat DataFast facts that do not match its own site. One says DataFast has a free tier. It does not. It has a 14-day free trial with no card required. We read every number below off the vendor's own live page on October 8, 2026. Where a vendor hides its price, we say so.

What DataFast does well

Verified on datafa.st and datafa.st/llms.txt on October 8, 2026.

• Revenue-first analytics. DataFast describes itself as focused on "business attribution, not just pageview analytics." It ties traffic sources, pages, campaigns and countries to revenue, MRR, LTV and churn.
• Wide payment coverage. The homepage lists native integrations with Stripe, LemonSqueezy, Polar and Shopify, and says you can connect more than one. Its llms.txt also names WooCommerce, Paddle and Dodo Payments.
• Cheap to start. Starter showed $9/month and Growth $19/month at the 10k monthly events tier, billed monthly. Yearly billing is "2 months free." Price rises with events.
• Easy to try. A 14-day free trial, "No card required."
• Agent access. An API, a CLI and an MCP server at datafa.st/api/mcp, with OAuth or token sign-in.
• Goals and funnels. Custom goals, conversion funnels, visitor journeys and alerts.
• Plugins for common builders. WordPress, Shopify, Webflow, Framer, Wix, Squarespace and Google Tag Manager, among others.

Three things to know before you leave or stay:

• There is no free plan. Search summaries that say otherwise are wrong.
• The default script uses cookies. DataFast says so in its FAQ and notes you may need a cookie banner for it. A cookieless script exists, which DataFast says is less accurate.
• Over your event limit, the dashboard locks. DataFast keeps tracking, but you must upgrade to see the data.

What its homepage and llms.txt do not list: A/B testing, heatmaps, session replay, or an import of Google Ads or Meta ad spend. That gap is why most of the tools below are on this list.

A note on reading DataFast's price. The numbers sit in an animated counter, so text scrapers often return a string of digits. We read the values from the page's own price markup. If you are budgeting, open datafa.st and move the event slider yourself.

At a glance: DataFast alternatives compared

"Not listed" means the vendor page we checked did not mention it. It does not prove the feature is absent.

The 8 best DataFast alternatives, ranked by job

1. Seline: the closest swap on price and idea

Price: Pro from $9/month, shown at 25,000 pageviews a month. 7-day free trial, no credit card required. No free plan ("No, we don't have a free plan"). Verified at seline.com/pricing.

Seline is the nearest thing to DataFast on this list. It is simple, private analytics with revenue. You connect Stripe, Polar or Shopify, or send revenue from any checkout as a custom event. It has funnels and visitor journeys and profiles. Seline describes itself as using no cookies and collecting no personal data.

Limits: fewer named payment providers than DataFast. No A/B testing, heatmaps or ad spend import were listed on its site. If you are leaving DataFast only to save a few dollars, check the tier you need on both pages first. They start at the same number.

2. Plausible: the default for simple privacy analytics

Price: Starter $9/month, Growth $14/month, Business $19/month at 10k monthly pageviews, billed monthly. Yearly billing is 2 months free. Starter covers one site. 30-day free trial, no credit card required. Verified at plausible.io.

Plausible is the safe pick if you want clean traffic numbers and nothing more. It is open source and lightweight. Ecommerce revenue attribution and funnels sit on the Business tier, not Starter. Goals and custom events are on every tier.

Limits: revenue is ecommerce goal revenue, not the Stripe MRR, LTV and churn view DataFast gives a SaaS founder. No A/B testing, heatmaps or ad spend were listed. We compare it with its own rivals in Plausible alternatives.

3. Fathom: privacy analytics for many sites

Price: from $15/month for up to 100,000 monthly pageviews and 50 sites. 7-day free trial, card required. No free plan. Verified at usefathom.com/pricing.

Fathom's entry tier gives you more room than most: 100k pageviews and 50 sites. That suits an agency or a founder with several small products. Its pricing page lists "Event and revenue tracking."

Limits: the trial needs a card, unlike DataFast. Funnels, A/B testing, heatmaps and ad spend were not listed on the pricing page.

4. Simple Analytics: the one with a real free plan

Price: free plan with 1 user, 5 websites and 1 month of history. Paid self-serve plan from $20/month billed monthly, with yearly at 2 months free. 14-day free trial, no credit card required. Verified at simpleanalytics.com/pricing.

If "free" is the requirement, this is the privacy-first answer. The free plan keeps only the latest month of data in your dashboard. That is fine for a side project, thin for a business.

Limits: no revenue tracking, funnels, A/B testing or heatmaps were mentioned on its pricing page. It is a traffic tool, not a revenue tool.

5. PostHog: product analytics with a big free tier

Price: free every month for 1M analytics events, 5K session recordings and 1M feature flag requests. Experiments are billed with feature flags. After the free tier, identified events are $0.000198 each and anonymous events $0.00005 each. No card required for the free tier. Verified at posthog.com/pricing.

PostHog is the pick if your questions are about the product, not the marketing site. Retention, cohorts, feature flags, experiments and session replay live in one place. The free tier is large enough that many small teams never pay.

Limits: it is built for engineers and product teams. A founder who wants a one-glance "which channel made money" view will find more setup here than in DataFast. We did not verify a native Stripe revenue view on its pricing page.

6. Usermaven: multi-touch attribution, sold by demo

Price: not published. The Business and Enterprise plans both lead to "Book a demo." Checked at usermaven.com/pricing.

Usermaven has moved toward marketing attribution. Its Business plan lists multi-touch attribution, paid ads attribution, custom attribution models, funnels, customer journeys, CRM and ad platform integrations, and an MCP server for AI agents. Every plan includes cookieless tracking, server-side tracking and unlimited websites.

Limits: no public price, so it is a harder swap for a solo founder used to DataFast's self-serve signup. No A/B testing or heatmaps were listed.

7. Cometly: ad attribution across many platforms

Price: not shown on the page. The page says "All plans tailored to fit your existing monthly pageviews." No free trial: "We don't run a free trial because attribution requires CRM and ad-platform setup to be useful." Checked at cometly.com/pricing.

Cometly is the attribution-heavy option. Both plans include "unlimited connections to Meta, Google, LinkedIn, TikTok, Microsoft, Reddit, and Snapchat, including server-side Conversion API." If you spend across many ad platforms and need conversions sent back to them, this is built for that.

Limits: no trial, no visible price, onboarding with a specialist. It is a paid-media tool, not a website analytics or testing tool. A/B testing and heatmaps were not listed.

8. Humblytics: testing and heatmaps on the same revenue data

Price: Business $79/month, Scale $279/month, Enterprise custom. Yearly billing is $65/month or $239/month equivalent. 14-day free trial, card taken at signup. No free tier. See pricing.

Humblytics is one privacy-first script that carries analytics, click and scroll heatmaps, funnels, no-code A/B testing and split URL tests. Revenue comes from Stripe or Foxy. Google Ads and Meta spend come in over read-only connectors and are matched to that revenue by utm_campaign, so you see ROAS per campaign. An A/B test can be scored on the revenue it produced, not on a click.

That is the honest lane. Pick Humblytics when you want to act on the revenue data, not only read it: test the page, see the heatmap, and check whether the ad spend paid back, in one place.

Agents can work with it too. A hosted MCP server and a Claude connector let Claude or Codex read traffic, funnels, heatmaps, ad spend and revenue. DataFast, PostHog and Usermaven ship MCP servers as well, so the protocol is not the difference. The data behind it is.

The limits, stated plainly:

• It costs more. $79/month against DataFast's $9. If you only need revenue by channel, DataFast or Seline is the better buy.
• Stripe and Foxy only for revenue. If you bill through LemonSqueezy, Paddle, Polar or Dodo, DataFast covers you and Humblytics does not.
• Google Ads and Meta only for spend. For TikTok, LinkedIn or Reddit, look at Cometly.
• No session replay. Pair it with Microsoft Clarity if you need recordings.
• Tests can auto-stop after a set duration but never auto-promote a winner. A person ships the change.

How to choose a DataFast alternative

Start with the job you are missing, not the price.

You just want revenue by channel, cheaply. Stay on DataFast, or try Seline. Both start at $9/month. DataFast covers more payment providers.

You want privacy analytics and do not need revenue. Plausible at $9/month for one site, Fathom at $15/month for up to 50 sites, or Simple Analytics free if one month of history is enough.

Your questions are about the product, not the site. PostHog. Its free tier covers most small teams.

You spend on many ad platforms. Cometly or Usermaven. Budget time for a demo and onboarding.

You want to test pages and see heatmaps on the same revenue, with Google Ads and Meta ROAS. Humblytics at $79/month. Check first that you bill through Stripe or Foxy. For the setup, read how to track Meta and Google Ads ROAS on Stripe subscriptions.

Two checks apply to any tool on this list:

1. Check what the price meters. DataFast meters events. Plausible and Fathom meter pageviews. PostHog meters events and recordings. One busy month behaves differently on each.
2. Check your payment provider. Revenue attribution is only as good as the connector. Confirm yours is supported before you start a trial.
