If code is free, why aren’t all apps native?
The state of coding agents can be summed up by this fact
Claude spent $20k on an agent swarm implementing (kinda) a C-compiler in Rust, but desktop Claude is an Electron app.
If you’re unfamiliar, Electron is a coding framework for building desktop applications using web tech, specifically HTML, CSS, and JS. What’s great about Electron is it allows you to build one desktop app that supports Windows, Mac, and Linux. Plus it lets developers use existing web app code to get started. It’s great for teams big and small. Many apps you probably use every day are built with Electron: Slack, Discord, VS Code, Teams, Notion, and more.
There are downsides though. Electron apps are bloated; each runs its own Chromium engine. The minimum app size is usually a couple hundred megabytes. They are often laggy or unresponsive. They don’t integrate well with OS features.
(These last two issues can be addressed by smart development and OS-specific code, but they rarely are. The benefits of Electron (one codebase, many platforms, it’s just web!) don’t incentivize optimizations outside of HTML/JS/CSS land.)
But these downsides are dramatically outweighed by the ability to build and maintain one app, shipping it everywhere.
But now we have coding agents! And one thing coding agents are proving to be pretty good at is cross-platform, cross-language implementations given a well-defined spec and test suite.
On the surface, this ability should render Electron’s benefits obsolete! Rather than write one web app and ship it to each platform, we should write one spec and test suite and use coding agents to ship native code to each platform. If this ability is real and adopted, users get snappy, performant, native apps from small, focused teams serving a broad market.
But we’re still leaning on Electron. Even Anthropic, one of the leaders in AI coding tools, who keeps publishing flashy agentic coding achievements, still uses Electron in the Claude desktop app. And it’s slow, buggy, and bloated app.
