The short version
- Each has a real cost: Avo editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.; ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Avo
- Editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.
- Avo governs event definitions but does not fix historic data, so an organisation with years of inconsistent tracking still faces the backfill problem it cannot solve.
- Code generation requires engineering teams to adopt generated modules in their build, and in practice some platform teams resist, leaving parts of the estate ungoverned and the plan only partly enforced.
- Inspector event volume is capped by tier, at 100,000 on free and one million on enterprise, so a high-traffic consumer product samples rather than observes everything and drift can hide in the unobserved portion.
- It is an additional tool in an analytics stack that already costs money, and justifying it requires the organisation to accept that its existing data is unreliable, which is a political argument as much as a budgetary one.
ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

- What is Avo best used for?
- Avo is most often used for a product team whose ios and android event names have drifted apart, making cross-platform funnels meaningless, an analytics lead who wants tracking changes to go through review rather than appearing in production unannounced, a company migrating between analytics tools that needs a canonical event schema independent of any vendor, an engineering organisation that wants event tracking mistakes caught by the compiler rather than by an analyst three months later. Of those, a product team whose ios and android event names have drifted apart, making cross-platform funnels meaningless and an analytics lead who wants tracking changes to go through review rather than appearing in production unannounced are not what ESLint is typically brought in for.

Answered from the vendors’ own pages
Avo: Is the free tier usable in production?
Yes. It includes two editors, code generation and 100,000 events observed in Inspector, which is enough for a small team.
ESLint: Does ESLint automatically fix code issues?
Many problems ESLint finds can be automatically fixed via the --fix flag. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.
SourceAvo: What exactly does code generation give me?
Type-safe tracking functions per platform, so a wrong event name or property type fails at compile time rather than in production data.
ESLint: How much does ESLint cost?
ESLint is completely free and open-source software maintained by the OpenJS Foundation. The project accepts voluntary donations from sponsors.
SourceAvo: Does Avo replace Amplitude or Mixpanel?
No. It governs the events those tools receive; you still need an analytics product.
ESLint: Can I write custom ESLint rules?
Yes. You can develop custom rules that work alongside built-in functionality through ESLint's plugin system, allowing complete customization for your project needs.
SourceAvo: How much is the Team plan?
250 US dollars a month billed annually for five editors, or 300 billed monthly, with extra editors at 50 dollars.
