WunderGraph

“Now, Cosmo presents all the relevant stats—how many queries run, their response times, and key performance metrics—making it much easier to communicate what's happening under the hood. This improved observability not only enhances request tracing but also helps teams understand how their queries run in a federated system. Ultimately, Cosmo has made it much easier for teams to buy into Federation.”

“We have experienced significant performance enhancements for our most complex queries since switching from Apollo to Cosmo. The query planning in Cosmo is more advanced and intelligently optimized.”

“I just liked the approach from WunderGraph, It felt optimized for the kind of development we were trying to do.”

“Our investment in WunderGraph's highly performant open-source platform will help boost eBay's API ecosystem and enable our teams to work faster and smarter in building products that help our sellers thrive.”

“Our infrastructure costs went from $14,000 with our previous provider down to $9,750 with Cosmo, even with some extra infra costs.”

“With Cosmo, we saved an estimated $178,000 just on building those features. That doesn't even include the cost of maintaining or supporting them long term.”

“Caching query planning was a game-changer in terms of performance for us.”

“The WunderGraph team jumped in to patch issues and build features that unblocked our migration.”

““We're running a whole new gateway plus router, and it's cheaper than running just our old federated gateway.””

““What surprised me most is that WunderGraph is a small team that can do big things. It feels like working with another team inside SoundCloud, not a vendor.””

““We were locked in, even though we weren't using those features, because we didn't have an alternative.””

“Even a single instance handles a couple of thousand requests per second, easily.”

“WunderGraph is currently handling hundreds of thousands of requests per second for us.”

“The federation spec has some loose and unclear details, and the behavior is undetermined.”

“It was brittle—failures could cost us a full day just to reconcile. With Cosmo, all of that went away.”

“Sometimes we forget it exists because it just works”

“The migration was just updating the DNS record”

“Each time a new plugin had to be written, we were losing two weeks of an engineer’s time.”

“We started building our own Federation Solution. We ended up implementing a home baked solution utilizing Apollo Rover and schema stitching. It worked for a while, but as we grew, it became more and more difficult to maintain, and harder for teams to adopt. We decided to look for a better solution.”

““By the end of the year, I'm aiming for a significant overhaul—where new engineers won't have to touch the BFF at all.””

““It was remarkably easy to get off the ground.””

““You log in, click on a graph, and see the supergraph with the subgraphs and the dotted lines.””

““We were duplicating effort, reviewing three PRs instead of one.””
