ESLint vs Teleport
Teleport
Cybersecurity
Certificate-based access to servers, Kubernetes, databases and apps, replacing shared credentials and VPNs
- From
- On request
- Free plan
- No
The short version
- Only ESLint has a free tier, so it costs nothing to try first.
- Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; Teleport pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
- Prices and features above were last checked on 31 August 2026.

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
Teleport
- Pricing is not published and is described as active users plus protected resources, so an autoscaling estate cannot forecast the bill and finance teams discover the true cost only after the first true-up.
- The proxy is a hard dependency on reaching production, so it needs its own high availability deployment and a tested break-glass path or an outage in Teleport becomes an outage in your ability to respond to outages.
- The open source Community Edition omits Access Requests, Device Trust and the FIPS builds, which are exactly the controls an auditor asks about, so the free tier rarely survives a compliance review.
- Self-hosting means running and upgrading a certificate authority and its backing store, and Teleport releases frequently enough that upgrade work becomes a standing operational commitment.
- Coverage across protocols is uneven in depth, so teams with legacy systems, unusual databases or bespoke network appliances find gaps that still require the old VPN to remain in place alongside it.

Questions people ask
- Is ESLint or Teleport better?
- Neither clearly leads. ESLint starts at Free and Teleport at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, ESLint or Teleport?
- ESLint has a free tier; the other does not. Paid plans start at Free for ESLint and On request for Teleport.

- Can I use ESLint for free?
- Yes. ESLint has a free tier, so you can try it without paying. Teleport starts at On request.
- What is ESLint best used for?
- ESLint is most often used for statically analysing javascript and jsx to find problems before runtime, automatically fixing issues with syntax-aware rewrites, enforcing a consistent code style across a team, running as a ci step to block non-conforming code. Of those, statically analysing javascript and jsx to find problems before runtime and automatically fixing issues with syntax-aware rewrites are not what Teleport is typically brought in for.
- What can ESLint do that Teleport cannot?
- Teleport covers Short-lived certificates, Protocol coverage, Session recording and replay, Access Requests.
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.
SourceTeleport: Is the open source edition usable in production?
Yes, but it lacks Access Requests, Device Trust and FIPS builds, which most compliance programmes end up requiring.
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.
SourceTeleport: How is it priced?
Not publicly. The vendor prices on active users and protected resources and provides a quote after a sales conversation.
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.
SourceTeleport: What happens if Teleport goes down?
Nobody reaches the resources behind it, so you need a highly available deployment and a documented break-glass procedure.
Teleport: Does it replace our VPN?
For anything you put behind it, yes. Legacy systems and appliances it does not support will keep the VPN alive.
