Disclosure: DevTools Review is not enrolled in an affiliate programme for either JetBrains AI or Zed — neither runs a publisher programme we could join, and we earn nothing from the links in this article. This is based on six months of daily JetBrains AI use across IntelliJ and WebStorm, and several months of Zed as a daily driver on a large TypeScript monorepo.
According to DevTools Review's hands-on testing across 11 AI coding tools, JetBrains AI and Zed keep showing up in the same "which AI coding tool" roundups, and it's a slightly odd pairing once you've actually used both. One is a $10-60/month plugin that only makes sense if you already live in an IntelliJ-family IDE. The other is a free, standalone, Rust-native editor whose most interesting feature has almost nothing to do with its own built-in AI. We rate JetBrains AI 3.5/5 and Zed 4/5, and they differ on 8 of the 15 dimensions we track — but the more useful framing isn't "which is better," it's "these solve different problems and a lot of developers will end up paying for both."
What JetBrains AI is actually good for
The case for JetBrains AI has nothing to do with model quality — it uses Claude, GPT-4, and Gemini like everyone else. The case is that it's welded into two decades of IntelliJ's own code analysis engine. When we asked Junie (JetBrains' coding agent) to add pagination to eight list endpoints in a Spring Boot app, it used IntelliJ's actual rename refactoring — not text replacement — ran the inspection suite after every change, caught two of its own bugs, fixed them, and re-ran. That's a meaningfully different reliability story than an agent operating purely at the text level, and it's the one thing a bolted-on extension in a different editor genuinely cannot replicate.
The tradeoff is the tax: $10/month personal or $20/month commercial for AI Pro, on top of whatever you're already paying for the IDE license itself.
What Zed is actually good for
Zed's pitch is almost the opposite. Its own in-editor agent is fine, not exceptional — solid multi-file edits, edit predictions that don't match Cursor's Tab. The reason to actually choose Zed is the Agent Client Protocol (ACP), which lets Claude Code, Codex CLI, or Gemini CLI drive the editor directly, with diffs rendered inline instead of scrolling past in a terminal pane you have to context-switch to. If you're already a daily Claude Code user, Zed doesn't ask you to replace that agent — it gives it a faster, more legible home, on top of cold starts under a second and a memory footprint a third of what Cursor uses on the same monorepo.
Zed also ships real-time human collaboration as a core feature (shared cursors, voice, actual co-editing) — a category JetBrains AI and most AI-focused tools simply don't compete in.
The correction worth making
Our own comparison table has been listing JetBrains AI's free tier as "not verified" — and that undersells what's actually changed. JetBrains restructured its pricing this year into four named tiers, and the bottom one is now a genuine free plan: unlimited local completions plus a small monthly credit allowance for cloud-model calls, sitting below AI Pro ($10 personal / $20 commercial) and AI Ultimate ($30 personal / $60 commercial). If you've seen JetBrains AI described elsewhere as "no free option, $10/month minimum," that's now out of date — worth checking before you write it off on price alone.
The bottom line
These aren't really substitutes for each other. If you're bought into a JetBrains IDE and want an agent that understands your refactors and inspections as well as your code, JetBrains AI's integration is real and hard to replicate elsewhere. If you want the fastest editor we've tested and a native home for an agent you already trust, Zed's ACP bet is the more interesting product — and it's free to try that bet with zero commitment. Plenty of developers we've talked to run both: JetBrains AI inside IntelliJ for the deep refactoring work, Zed for everything else.
