StackStats.app VS Formo.so

StackStats.app's answer

StackStats runs 100% locally on your machine — your subscriber data never touches a server. It also goes far beyond what Substack shows natively: bot-filtered open rates, cohort retention, superfan identification, dead subscriber detection, and content-to-growth correlation. No subscription, no account, no cloud. Pay once, own it forever.

Formo.so's answer:

Formo is the only analytics and attribution platform built specifically for DeFi and onchain apps. Unlike general-purpose tools like Google Analytics or Mixpanel, Formo natively understands crypto: it automatically tracks wallet connections, chain switches, transactions, and signatures alongside traditional web metrics like pageviews and sessions, with no custom code required.

What sets Formo apart: it connects the full user journey from offchain (UTM campaigns, referrers, social channels) to onchain (transactions, volume, revenue), so DeFi teams can measure real ROI: not just vanity metrics. Its Wallet Intelligence layer turns anonymous wallet addresses into rich user profiles, revealing net worth, DeFi positions, token holdings, and cross-platform activity. It also includes token-gated forms for community engagement with onchain verification (Ethereum, Solana, World ID, Passport).

Formo is GDPR-compliant by default: no third-party cookies, no IP storage, no device fingerprinting so teams don't need cookie consent banners. The SDK is 100% open source (MIT License).

StackStats.app's answer

Most newsletter analytics tools are cloud-based SaaS with monthly subscriptions. StackStats is a one-time purchase that runs entirely on your device. For Substack writers who care about privacy — especially those with paid subscribers — that's a meaningful difference. You also get analytics features that don't exist anywhere else, like bot-filtered open rates and cohort retention, without having to migrate away from Substack.

Formo.so's answer:

DeFi teams that try to use Google Analytics, PostHog, or Mixpanel for onchain apps run into the same wall: these tools were built for web2 and have no native concept of wallets, transactions, or onchain identity. Stitching together a custom data stack takes weeks and still produces incomplete data. Formo is purpose-built for crypto. It gives you web analytics, product analytics, onchain attribution, wallet intelligence, and community forms in a single platform with same-day setup.

Customers skipped weeks of analytics infrastructure by switching to Formo. Competitors like Spindl, Cookie3, and Safary focus narrowly on attribution or on-chain data; Formo covers the full onchain growth stack. Formo also connects with AI tools like Claude and Codex via MCP and provides a CLI and API for teams that want to query or export their data programmatically.

StackStats.app's answer

I built StackStats because Substack's native analytics weren't cutting it. I wanted cohort data, real open rates (not bot-inflated), and a way to identify which posts were actually driving subscriber growth — but every tool I found was either cloud-based or required migrating off Substack entirely. So I built a local app that works with Substack's own CSV exports. No migration, no cloud, no subscription.

Formo.so's answer:

Formo was built by onchain builders who experienced firsthand how painful it was to measure growth in DeFi. Existing analytics tools were designed for web2 and couldn't handle the fundamental primitives of crypto: wallets, transactions, onchain data. Teams were left building their own fragmented data stacks or flying blind.

Formo was created to solve this: a data platform designed from the ground up for DeFi, combining web analytics, onchain attribution, wallet intelligence, and community tools in one place. The team is committed to our long-term mission: making analytics simple enough that teams can focus on shipping and growth, not on data infrastructure.

StackStats.app's answer

Serious Substack writers who are frustrated by Substack's shallow native analytics and want real data to drive growth — without moving their subscriber data to the cloud.

Formo.so's answer:

Formo's primary audience is growth-minded teams building DeFi and onchain apps, specifically founders, product managers, and growth leads at crypto startups who need to understand user behavior across the full offchain-to-onchain journey. This includes teams building DEXes, lending protocols, vaults, wallets, and other DeFi primitives on EVM chains and Solana.

Secondary audiences include crypto marketing teams running paid campaigns and community programs who need attribution data, and technical teams that want API or MCP access to raw analytics data for custom tooling.
