ESLint vs Microsoft Edge
Microsoft Edge
Technology
Microsoft's Chromium-based browser, distinguished by IE mode for legacy applications and by its integration with Microsoft 365 management.

The short version
- Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; Microsoft Edge outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.

- Microsoft 365 organisations that want browser sessions covered by Purview DLP and conditional access without a separate secure browser productnot ESLint

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
Microsoft Edge
- Outside the European Economic Area, Edge cannot be uninstalled from Windows, and Windows components such as Widgets, help links and taskbar search results open in it whatever the default browser is set to, so an organisation standardising on Chrome still has to manage and patch Edge.
- It is Chromium downstream, so Manifest V3 applies exactly as it does in Chrome; full-strength blocking extensions cannot run, and Microsoft's add-ons store adds a second review process rather than a workaround.
- Almost all of its advantage is conditional on Microsoft 365 and Entra ID; a Google Workspace or AWS-centred organisation gets Chromium plus Microsoft's promotional surfaces and none of the Purview, Intune or conditional access value.
- Consumer-facing features including Copilot, the Discover pane, shopping notifications and sidebar apps default to on and reappear after feature updates, so suppressing them requires a maintained policy set rather than a one-off configuration.
- IE mode is a bridge with a maintenance owner attached: the Enterprise Mode Site List must be curated by somebody, and MSHTML receives security fixes but no new capability, so an application parked there gains nothing and its eventual rewrite is only deferred.
- By default browsing data feeds Microsoft services for Copilot, Discover and shopping features, which in a regulated environment turns the deployment into a policy exercise before it can be approved.

Questions people ask
- Is ESLint or Microsoft Edge better?
- Neither clearly leads. ESLint starts at Free and Microsoft Edge at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, ESLint or Microsoft Edge?
- ESLint starts at Free and Microsoft Edge at Free.
- Does ESLint or Microsoft Edge run on more platforms?
- ESLint runs on Browser-based JavaScript, Node.js, Any JavaScript environment. Microsoft Edge runs on Web.
- Can I use ESLint for free?
- Both have a free tier, so you can try either at no cost before committing.
- 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 Microsoft Edge is typically brought in for.
- What can ESLint do that Microsoft Edge cannot?
- Microsoft Edge covers Internet Explorer mode, Enterprise Mode Site List, Entra ID integration, Purview DLP for browsing.
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.
SourceMicrosoft Edge: Can I uninstall Edge from Windows?
In the European Economic Area, yes, because the Digital Markets Act requires it. Elsewhere you cannot, and several Windows components will continue to open it regardless of your default browser.
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.
SourceMicrosoft Edge: How long will Internet Explorer mode be supported?
Microsoft has committed to supporting IE mode in Edge through at least 2029. It is a migration window rather than a permanent home, since the underlying MSHTML engine gets security fixes but no new capability.
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.
SourceMicrosoft Edge: Do Chrome extensions work?
Yes. Edge installs extensions from the Chrome Web Store as well as its own store. Manifest V3 restrictions apply identically, so extensions that Chrome no longer supports do not work here either.
Microsoft Edge: Is it worth deploying if we are not a Microsoft 365 organisation?
Usually not for the management features, which depend on Entra ID, Intune and Purview. Without that stack it is Chromium with a different interface and additional Microsoft promotion.
Microsoft Edge: Does it run on Linux?
Yes, there are official Linux builds. Some Windows-specific features, including IE mode, are not available there.
