Lumenlytic vs Pirsch

Pirsch is a privacy-first analytics tool from Germany with a genuinely low entry price. The Standard plan is $6/month for 10k pageviews and includes 50 sites, unlimited members and unlimited retention. The Plus plan at $12 adds unlimited sites, funnels, teams, custom domains and white-label reporting. It is cookie-free, and its open-source core can be self-hosted. For an agency running many small client sites that needs unlimited history, this is an unusually strong package at the low end. It is the kind of pricing that makes you reconsider your assumptions about what analytics has to cost. The white-label and team features on Plus are especially relevant to agencies that resell reporting under their own brand.

The important detail is the meter. Pirsch bills pageviews, and custom events (plus a share of session-extension events) count toward the same allowance. The volume slider is steep at the low end but flattens out: Standard is $6/mo at 10k pageviews, $36 at 500k and $54 at 1M, with Plus at $12, $99 and $159 respectively. That is a fair pageview price, not the order-of-magnitude trap the entry rate might suggest — but it still rises with traffic, so a busy single site pays more over time while an event plan with a fixed allowance does not. Do the arithmetic at your expected peak, not at today's numbers.

Lumenlytic bills events too, so custom events are counted, but it includes a far larger allowance at each price: Solo is $15/mo for 1.5M events and five sites, and the free plan covers 200k. The trade is retention and site count — Pirsch offers unlimited retention and 50 sites at entry, where Lumenlytic caps retention at two years and sites per plan. Lumenlytic also adds Core Web Vitals, which is not a headline feature for Pirsch. So the two products are optimised for different buyers: Pirsch for many small sites with long history, Lumenlytic for fewer sites with high volume and a predictable bill. Neither is wrong; they simply fit different shapes of customer.

So this comes down to scale and requirements. At very low traffic with a need for unlimited retention, many sites and a low flat entry cost, Pirsch is excellent and easy to recommend. As traffic grows, the pageview price rises — $36 at 500k, $54 at 1M — while Lumenlytic's Solo plan covers 1.5M events for $15. For agencies with many tiny sites, Pirsch's 50-site entry and unlimited retention are a real advantage; for a single growing site, the economics favour Lumenlytic. The right question is not which tool is cheaper in general, but which tool is cheaper for your specific traffic shape and site count. Run the numbers for your busiest month, not your quietest, and the choice usually becomes clear.

Total cost is dominated by your traffic shape. At a few thousand pageviews a month, Pirsch's $6 entry price is hard to beat, and its unlimited retention and 50 sites make it excellent for an agency with many quiet clients. At a million pageviews Pirsch is $54/mo, while Lumenlytic's Solo plan covers 1.5M events for $15. That is a real gap but not a dramatic one, and Pirsch's 50 sites and unlimited retention may justify it for an agency. Add the value of those extras if you need them, but do not pay for headroom you will never use.

If you are deciding today, pick Pirsch when you manage many small sites, need unlimited retention and want the lowest possible entry price. Pick Lumenlytic when you have one or a few growing sites, want event pricing that does not explode with traffic and prefer a managed service with Core Web Vitals. Agencies sometimes use both: Pirsch for a portfolio of tiny client sites and a higher-volume tool for the flagship. Run the arithmetic on your busiest month and choose the plan that stays comfortable when traffic is highest.

Support and reliability differ by model. Pirsch's open-source core lets you self-host and control the stack, while its managed service is a small, focused operation in Germany. Lumenlytic is managed only, which removes operational work but also removes your ability to run the software yourself. For an agency that already hosts client infrastructure, Pirsch's self-hosted path can be attractive. For a team without that capacity, the managed service is the safer default. Check export, backup and support terms in both cases, and weigh the vendor's size against your tolerance for doing more yourself.

Set a trigger to revisit. If your pageview count climbs past a million, Pirsch's slider price outpaces Lumenlytic's flat event allowance, and the gap widens as traffic grows. If your site count grows instead of your traffic, Pirsch's 50-site entry may remain the better deal. Those are different growth directions, and it is worth knowing which one you expect. Review the numbers at your busiest month and switch when the meter stops matching your shape. A yearly check keeps a low-entry plan from quietly becoming an expensive one. If your site count is growing faster than your traffic, the opposite conclusion may hold, so revisit the numbers whenever your shape changes. The meter is the thing to watch, not the number on the pricing page. Always check it.
