Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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
Termly
- A standard plan licenses one website, so an agency or a business with several brand domains multiplies the headline price by the number of sites and the cheap option stops being cheap at four or five domains.
- Generated policies are templates conditioned on questionnaire answers, so they describe the data practices you claimed rather than the ones your code performs, and a regulator comparing the policy to actual tracking finds the gap not the vendor.
- Banner view limits apply on the lower tiers, and a site that spikes in traffic can exhaust its allowance mid month, which is the worst possible moment for consent handling to degrade.
- It covers websites well but has little for mobile apps, so a company with an iOS and Android app alongside its site needs a second consent mechanism and a second consent record.
- There is no data mapping, subject rights automation or vendor inventory, so any company that grows into real privacy programme obligations outgrows Termly entirely rather than upgrading within it.

Answered from the vendors’ own pages
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.
SourceTermly: Does one Termly plan cover all my websites?
No. A standard plan licenses one website. Multiple domains need multiple licences or an agency arrangement, and this is the single most common surprise on the bill.
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.
SourceTermly: Are the generated policies legally sufficient?
They are templates conditioned on your answers and are not legal advice. They are proportionate for a simple site and inadequate where actual data flows are complex or regulated.
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.
SourceTermly: Is there a genuinely free plan?
Yes, one basic policy, one site, 10,000 monthly banner views and quarterly cookie scans, with no card required.
Termly: Does it handle US state privacy opt-outs?
Yes, including a do not sell or share mechanism and regional rule sets, alongside GDPR consent for EU visitors.
