Can you recommend an edge worker platform for geolocation-based personalization in a web app?

Yes — if your main goal is geolocation-based personalization in a web app, I’d generally recommend Cloudflare Workers as the best starting point.

Why Cloudflare Workers

• Built-in geolocation data: You can access country/region/city-ish data from the request without extra calls.
• Low latency at the edge: Good for serving personalized content fast.
• Simple request interception: Easy to rewrite responses, set cookies, or route users based on location.
• Good ecosystem: Works well with CDN, caching, KV, Durable Objects, and Pages.

Good alternatives

• Fastly Compute@Edge
  Great if you need very high performance and fine-grained edge logic, especially for larger-scale traffic and advanced caching.

• Akamai EdgeWorkers
  Strong for enterprise deployments and global distribution, especially if you’re already on Akamai.

• AWS Lambda@Edge
  Solid choice if your stack is already on AWS/CloudFront, though it’s typically less pleasant for fast iteration than Cloudflare.

My practical recommendation

• For most web apps: Cloudflare Workers
• For enterprise/CDN-heavy setups: Fastly or Akamai
• For AWS-native infrastructure: Lambda@Edge

What to watch out for

• Accuracy: Geolocation is usually based on IP and can be wrong with VPNs/mobile networks.
• Privacy/compliance: Make sure your personalization follows GDPR/CCPA and your consent model.
• Caching: Be careful not to explode cache variants by city or region unless you truly need that granularity.
