Analytics
28 products ranked by how much of their useful core an AI coding agent can realistically reproduce.
Umami Cloud
The software is open source, so the cloud subscription is mostly paying for managed hosting, upgrades, and not touching a server.
Bitly
A slug, a lookup, a 302, and a row in a table. Cloudflare Workers plus KV and D1 does the whole job on the free tier, and QR codes are one library call. The only thing you are really buying is that bit.ly resolves links created in 2012 and will presumably still resolve them in 2032, which is an institutional promise rather than a technical one. If the links are going in a magazine ad or on packaging, that promise is worth something. If they are going in this week's newsletter, it is worth nothing, and Growth is 420 USD a year.
Fathom Analytics
A simple privacy analytics clone is very buildable; the paid service is hosted compliance posture, uptime, data retention, and polished reporting.
Plausible
Basic pageview/event analytics are easy, and Plausible's own code is open source; the paid value is hosted reliability, maintenance, and support.
Matomo Cloud
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Matomo Cloud, run first-party web analytics with goals, campaigns, and user-owned data. The hard boundary is mature analytics depth, privacy controls, hosted operations, and premium plugins, plus data pipeline reliability and analytical depth.
Baremetrics
The visible subscription analytics loop is buildable, but a credible replacement needs more than the first screen. Baremetrics earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
Cabin
The visible privacy web analytics loop is buildable, but a credible replacement needs more than the first screen. Cabin earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
GoSquared
The visible web analytics + customer data loop is buildable, but a credible replacement needs more than the first screen. GoSquared earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
June
The visible B2B product analytics loop is buildable, but a credible replacement needs more than the first screen. June earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
Pirsch
The core loop is buildable, but a dependable replacement becomes a substantially larger project. For Pirsch, collect cookieless page views and custom events with compact dashboards. The hard boundary is hosted reliability, privacy operations, apis, email reports, and scale, plus data pipeline reliability and analytical depth.
Usermaven
The visible product + web analytics loop is buildable, but a credible replacement needs more than the first screen. Usermaven earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
Simple Analytics
Pageview analytics, events, dashboards, and exports are very buildable; paid value is hosted privacy posture, reports, reliability, and support.
ChartMogul
The visible subscription analytics loop is buildable, but a credible replacement needs more than the first screen. ChartMogul earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
LnkFlow
A short link that 302s, logs the click, and injects UTMs is genuinely straightforward on Cloudflare Workers and KV, and the prompt below builds exactly that. What is not straightforward is the loop back out to the ad platforms. Meta and Google bid against the conversion events you send them, and since ATT the browser pixel misses a large share of purchases, which is the entire reason the Conversions API and offline conversion import exist. Closing that loop means persisting fbclid and gclid at redirect time, carrying that identity to a sale that happens days later on another device, posting a Purchase with a stable event_id so it deduplicates against the pixel, rebuilding fbc in Meta's fb.1.{timestamp}.{fbclid} form, importing offline conversions to Google on gclid, gbraid, or wbraid, and reversing all of it on refund. Every one of those fails silently. That is the expensive part: the dashboard still shows clicks while the bidder optimizes against nothing.
DataFast
The pageview half of DataFast is the same contained build as Plausible or Umami. The revenue half is where it stops being a contained effort. Attribution is only worth anything if the anonymous visitor who found your launch post on a phone is still recognisably the customer who pays from a laptop three weeks later, and that stitching is exactly what an agent will hand you a naive version of. A localStorage id plus an email match at signup does get you a channel table that is directionally right for a single-domain solo product, which is genuinely worth having. It also quietly under-counts every cross-device path, every privacy browser that clears storage between visits, and every customer who pays with a different address than they signed up with. You can build the dashboard in a contained effort. Trusting it enough to move ad spend is the part that keeps costing you weekends.
Piwik PRO
The visible privacy analytics suite loop is buildable, but a credible replacement needs more than the first screen. Piwik PRO earns its keep through ingestion, storage, reliability, so expect a substantial build and a narrower personal scope.
Crazy Egg
Do not mistake the interface for the product. Crazy Egg's durable value is ingestion, storage, reliability, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
Amplitude
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Amplitude, build a bounded event explorer for funnels, cohorts, and retention on one product. The hard boundary is behavioral data platform, experimentation, identity, governance, and scale, plus data pipeline reliability and analytical depth.
FullStory
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For FullStory, collect explicit product events and targeted debug snapshots with strong privacy controls. The hard boundary is high-fidelity replay, privacy redaction, indexing, search, storage, and compliance, plus data pipeline reliability and analytical depth.
Mixpanel
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Mixpanel, collect a small transparent event stream and build funnels and retention locally. The hard boundary is large-scale ingestion, identity handling, query engine, governance, and product expertise, plus data pipeline reliability and analytical depth.
Heap
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Heap, instrument explicit first-party events and avoid automatic capture of unrelated user behavior. The hard boundary is automatic capture engine, identity graph, data science, governance, and enterprise operations, plus data pipeline reliability and analytical depth.
Lucky Orange
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Lucky Orange, collect limited consented interaction events and build basic heatmaps for an owned site. The hard boundary is session replay, chat, surveys, funnels, privacy tooling, and always-on ingestion, plus data pipeline reliability and analytical depth.
Mouseflow
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Mouseflow, capture a small consented session sample and render a simple playback for debugging. The hard boundary is capture compression, privacy redaction, storage, heatmaps, funnels, and hosted scale, plus data pipeline reliability and analytical depth.
Smartlook
Do not mistake the interface for the product. Smartlook's durable value is ingestion, storage, reliability, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
Woopra
Do not mistake the interface for the product. Woopra's durable value is ingestion, storage, reliability, which a solo one-shot build cannot reproduce responsibly. The prompt therefore builds only the closest honest personal consolation tool.
PostHog
First-party collection and a dashboard that answers your top five questions is achievable solo, and PostHog's free tier covers a million events a month before you pay anything. What the bill buys past that is the rest of the platform: session replay, feature flags, SQL over years of events, and ingestion that stays correct while your event schema drifts underneath it.
NicheMaps
You can build a personal watchlist that checks a handful of store listings and ad-library pages, but NicheMaps' value is a continuously refreshed catalog of millions of iOS/Android apps with ad-status, IAP, velocity, and creative evidence you cannot rebuild.
Vernigo
You can build filters, bookmarks, and an outlier score over a small set of YouTube channels, but Vernigo's product is the continuously refreshed corpus: millions of videos, channel baselines, niche-level supply and demand signals, and ranking data improved by how thousands of users interact with the library. A one-shot app can reproduce the interface and formula, not the dataset that makes the results useful.
