The short version
- Each has a real cost: Deno egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications; 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.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Deno
- Egress bandwidth overage costs $0.20/GB which can become expensive for high-traffic applications
- CPU time overage is $0.10/hour on Pro and Builder tiers, adding to costs for compute-intensive workloads
- Enterprise pricing is not disclosed; requires sales contact
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 Deno or Microsoft Edge better?
- Neither clearly leads. Deno 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, Deno or Microsoft Edge?
- Deno starts at Free and Microsoft Edge at Free.
- Does Deno or Microsoft Edge run on more platforms?
- Both run on Web, so platform support will not decide this one for you.
- Can I use Deno for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Deno best used for?
- Deno is most often used for running typescript natively without transpilation overhead, migrating node.js applications to secure-by-default runtime, deploying edge functions and serverless containers seamlessly, consolidating developer tools into single binary. Of those, running typescript natively without transpilation overhead and migrating node.js applications to secure-by-default runtime are not what Microsoft Edge is typically brought in for.
- What can Deno 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
Deno: How much does Deno Deploy cost?
Deno Deploy offers a free tier at $0/month, Pro at $20/month, and Builder at $200/month. Enterprise has custom pricing. All plans include base request and bandwidth limits, with overage charges for additional usage.
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.
Deno: What are Deno Deploy's overage charges?
Egress bandwidth overages cost $0.20 per GB. CPU time overages are $0.10 per hour on Pro and Builder tiers. Memory time and KV database operations also incur charges beyond included limits.
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.
Deno: How many apps can I deploy on Deno's free plan?
The free tier includes 10 apps with up to 1 concurrent build. Pro tier supports 50 apps with 3 concurrent builds, and Builder supports 10,000 apps with 20 concurrent builds.
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.
Deno: How many team members can access Deno Deploy?
The free tier supports up to 3 team members. Pro supports 10 team members. Builder supports 25 team members. Enterprise has custom seat limits.
SourceMicrosoft 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.
