Electron packages web apps as native desktop applications. Powers VS Code, Slack, Discord, and hundreds of other desktop apps. Criticized for memory usage.

Inception Labs launched Next Edit inside the Continue extension, bringing Mercury Coder's diffusion-based architecture to VS Code and JetBrains. Unlike autoregressive autocomplete that generates left-to-right, Mercury predicts multi-line edits across your entire file simultaneously — deletions, additions, and structural changes at once. Common patterns it handles: converting callbacks to async/await, extracting functions, renaming variables across call sites, and squashing code smells. Latency is under 100ms so suggestions appear before you finish thinking. The diffusion architecture ($0.25/M input, $1/M output) is 5-10x faster than comparable autoregressive models. Available via Models Add-On in Continue.
Reviewer scorecard
“Ship desktop apps with your web stack. VS Code proves Electron apps can be fast with the right engineering.”
“I've used next-edit features in other tools but the sub-100ms latency here is genuinely different — it's below my perception threshold, which means it doesn't break flow. The multi-line simultaneous edit understanding is real; it caught a refactor pattern I was about to manually do across 6 call sites.”
“Memory hog that bundles a full Chrome instance. Tauri is the modern alternative with 10x smaller bundles.”
“The benchmarks are impressive but 'trained on real edit sequences' is doing a lot of work here. Until I see how it handles domain-specific refactors in large codebases with complex type hierarchies, I'm skeptical it beats Cursor's native next-edit on anything beyond textbook patterns.”
“Tauri and native solutions are the future for desktop apps. Electron was necessary but its era is ending.”
“Diffusion LLMs applied to code editing is the most underrated architectural bet in AI tooling right now. Autoregressive generation was always the wrong primitive for editing — you don't write a diff token by token. Mercury's approach is structurally correct and the speed numbers suggest it scales without compromise.”
“Even for non-heavy-coders, the 'fix code smells' and 'rename across call sites' use cases are exactly the tedious tasks that make coding feel like work instead of creation. Sub-100ms means zero cognitive interrupt. This is the kind of AI assist that disappears into the background in a good way.”
