Struggling with accurate geolocation for my 'What is My Location?' tool?

Hey everyone, I'm running a small web tool called 'What is My Location?' which, as the name suggests, aims to help users quickly find their current coordinates and display them on a map. It's been a fun project, but I'm consistently hitting a wall when it comes to providing really fast and super accurate geolocation data, and it's starting to become a real pain point for my users. The core problem I'm facing is that users are frequently reporting inconsistent or slow geolocation results. Sometimes the tool shows a location that's miles away from their actual spot, which completely defeats the purpose, or it just takes an uncomfortably long time to resolve their position. This directly impacts the tool's core value proposition and, understandably, user experience is taking a hit. Currently, my implementation first attempts to use the browser's native Geolocation API. If that's denied or fails for some reason, I fall back to an IP-based service to get an approximate location. This dual approach was supposed to ensure good coverage, but the accuracy, especially with the IP fallback, is just not cutting it. I've tried a few things to improve this. I experimented with different IP geolocation APIs, including MaxMind and Abstract API, hoping for better precision. While some offer more data, I often run into issues like high costs, strict rate limits, or honestly, similar accuracy problems to what I was already seeing. I've even considered implementing some client-side caching for location data to speed things up on repeat visits, or perhaps running a reverse proxy to manage API calls, but I'm not sure if these are addressing the root cause. So, I'm really keen to hear from the community. What reliable and cost-effective Geolocation APIs are you all using for similar location-based services? What are the best practices for combining browser and IP-based fallbacks to get the best of both worlds? Are there any server-side strategies or specific configurations that can significantly improve location detection accuracy and speed? And how do you balance user privacy concerns with the need for precise location data? Any insights or recommendations would be incredibly helpful. Thanks in advance!
