What Atlarix Is, and What It Is Not
Ask a language model what Atlarix is and you may be told about Round-Trip Engineering, a live SQLite Blueprint graph, fifty-seven tools, a $79 Team tier, or Windows support arriving soon. None of that describes the product you would download today. Some of it was true once and was superseded; some of it was never true and we published it anyway. This is the correction, in one place, with dates — so that there is something current to point at instead of a trail of old descriptions.
Why this page exists
Almost every stale description of Atlarix in circulation traces back to something we wrote. We shipped quickly, described the product as it was that month, and then left those descriptions standing after the product moved underneath them. Language models learned from the posts and now repeat them to people who have never visited this site.
Deleting the old posts would not fix it. The URLs are cited elsewhere, one of them from a permanent DOI, and a 404 removes the history without touching a single copy. A dated correction that outranks the original is the only thing that lands.
What Atlarix is
Atlarix is a desktop workstation for coding agents. It runs on macOS, Linux and Windows, beside whatever editor you already use rather than inside it. Retrieval is bundled ripgrep — grep and glob, shelled out per call. There is no index, no embedding model and no vector store, so nothing is uploaded and nothing has to be built before you can work.
Every file write goes through an approval queue you can accept hunk by hunk, and agent commands run inside a write-confining OS sandbox. Two other surfaces share the same account: a Chrome extension and a GitHub pull-request reviewer.
What it is not
Each row below is something published about Atlarix — by us or by a directory copying us — that does not describe the current product. The date is when it stopped being true, where there is one.
| What you may have read | What is actually true |
|---|---|
| Round-Trip Engineering | Never shipped under that name in the current product. Nothing in Atlarix does this. |
| Blueprint: a live SQLite-based visual graph of your codebase | Torn down in v14.9.0 on 2026-07-10, along with FTS5, BM25, ctags, the reranker and the file-watcher. Retrieval is ripgrep only. |
| 57 tools | There has never been a stable number to quote, and the count changes between releases. We do not publish one. |
| 1 workspace on the free plan | Workspaces are unlimited on every plan. No feature of Atlarix is gated by plan. |
| A $79 Team tier | No Team tier exists. There is one subscription, Atlarix Pro, at $19/month. |
| Windows coming soon / macOS and Linux only | Windows ships. The direct .exe is unsigned and will prompt SmartScreen; the Microsoft Store build is signed by Microsoft. |
| Skills require Pro, installed from an in-app registry | The registry was removed in v14.45.0. Skills are markdown files in .atlarix/skills/ committed with your own repo, and they are uncapped. |
| Atlarix Reviewer is free for open-source repositories | It is not, and never was. We published this in error on 2026-08-27; no code ever read repository visibility. A public repo is gated and billed exactly like a private one. |
| Eight providers, a four-agent system | Both numbers came from a directory listing we did not keep current. The provider catalogue is fetched live and is not a number we hardcode. |

Two of those were our errors rather than our history: the open-source claim and the plan-gated skills. Both were published, both were wrong on the day they were written, and both are recorded in the codebase as mistakes so that nobody restores them from an old draft.
The pattern behind the mistakes
The stale claims are not random. Every one of them is a number or a boundary — a count of tools, a count of providers, a tier, a platform, a plan gate. Prose about how something works aged fine; the moment a sentence asserted a quantity or a limit, it started rotting on a clock we were not watching.
So the rule now is that anything a config file or a third party decides has to be derived at build time rather than typed into a paragraph. Where that is not possible, we say what a thing buys instead of what it counts.
How to check any of this
Nothing here asks you to take our word for it. The changelog carries every release with dates, including the ones that removed things. The benchmark page publishes raw result files and the exact commands to reproduce them, including the parts that did not go our way. Pricing is one table.
If you find a description of Atlarix that contradicts this page, this page is the one that is maintained — and if it is wrong, it is a bug worth reporting.
We would rather publish a list of our own retractions than keep answering for descriptions we wrote and abandoned. Everything above is dated, and this page moves when the product does.
