Interop or inter-oops?
Launching Interop 2026
Browsers hit 99% together—fans cheer while privacy gets side-eye
TLDR: Interop 2026 launches after 2025 delivered near‑perfect browser consistency, promising fewer developer headaches. Commenters cheered the 99% but questioned 0% privacy testing and dropped investigations, debating whether headline scores beat real user protection—making this a big deal for everyone using the web.
Interop 2026 just dropped, and the big browsers—Apple, Google, Microsoft, Mozilla—are promising a smoother, more consistent web. After 2025’s push, the scoreboard shows near-perfect harmony: Firefox climbed from 46 to 99, while the overall score hit 95, meaning fewer “why does this site break in Browser X?” headaches. Shiny new toys landed consistently too, like view transitions, anchor-based positioning, and the Navigation API. The vibe? Developers are thrilled to join the 99% club and finally stop wrestling CSS gremlins.
But the comments lit up fast. User culi linked the Interop dashboard and threw cold water on the party: “they kinda gave up on the investigations?”—calling out 0% privacy testing and asking if the tough stuff got benched while the easy wins got gold stars. Cue debate: one camp loves fewer cross-browser bugs; the other wants answers on privacy and real-world behavior, not just test passes. Meanwhile, linolevan’s “Oops, accidental dupe” became an instant meme, as folks joked about the Interop Olympics—“everyone gets gold except privacy”—and whether those 97% parity numbers mostly live in experimental builds. Drama, jokes, and data links—classic web dev theater, now with more dashboards and fewer broken grids.
