Products in this category do not usually die loudly. They get acquired, folded into something else, renamed, or quietly moved behind a paid tier — and the internet keeps describing them the way they were.
That gap is easy to observe. In spot checks during September 2026, AI-generated search summaries still described Supermaven as the engine behind Cursor's autocomplete, and still described Windsurf's Cascade agent as the current product. Both statements were accurate once. Neither is accurate now.
This page is the correction. Every claim below points at the vendor's own announcement and carries the date it was published, so you can check it rather than trust it.
Supermaven — folded into Cursor's Tab
Anysphere, the company behind Cursor, acquired Supermaven roughly a year before the shutdown notice. On November 21, 2025, Supermaven published a post titled "Sunsetting Supermaven" confirming the product was being discontinued and that its autocomplete capability had been integrated into Cursor's Tab feature.
The detail most summaries get wrong is that this was not a clean switch-off. Existing customers were issued prorated refunds for the remaining time on their subscriptions, and the vendor said it would keep providing free autocomplete inference to existing customers for the foreseeable future — specifically naming Neovim and JetBrains users, who had no Cursor equivalent to move to. What did stop was the agent conversation feature. VS Code users were pointed at Cursor and its newer autocomplete model.
If you are choosing today: there is no Supermaven to sign up for. The capability lives in Cursor. If you are a Neovim or JetBrains user who was relying on the standalone plugin, treat it as running on borrowed time rather than as a supported product.
Windsurf — renamed Devin Desktop
This one is a rename, not a shutdown, and the difference matters. Cognition published "Windsurf is now Devin Desktop," and its Devin Desktop page now calls it the new name for Windsurf. Windsurf users received it as a standard over-the-air update, and the announcement stated plainly that plan, pricing, extensions and other features stayed the same. The editor remains backwards-compatible with Windsurf and VS Code extensions and keybindings.
What did change is the agent underneath. Cascade was replaced by Devin Local, rewritten from scratch in Rust with the same capabilities and settings, which Cognition describes as up to 30% more token efficient and which adds subagents. The legacy Cascade agent remained usable through July 1 for incremental migration. The release also made the Agent Command Center — a Kanban view over every local and cloud agent — the default surface, added Spaces for sharing context between agents, and shipped support for the Agent Client Protocol, so Codex, Claude Agent, OpenCode and in-house agents run inside the same editor.
If you are choosing today: both windsurf.com and codeium.com/windsurf now resolve to the Devin Desktop page. Plans and pricing carried over from Windsurf: there is still a Free plan, and Pro is $20/mo on Devin's pricing page. Our directory entry is Devin.
Sora — the API shuts down on September 24, 2026
This is the most time-sensitive item on the page. OpenAI's help center states that the Sora web and app experiences were discontinued on April 26, 2026, and that the Sora API will be discontinued on September 24, 2026.
The developer-facing side is documented separately and is unusually specific. OpenAI's deprecations page records that developers using the Videos API and the Sora 2 video generation aliases and snapshots were notified on March 24, 2026 of their removal from the API on September 24, 2026. The listed identifiers are sora-2, sora-2-pro, sora-2-2025-10-06, sora-2-2025-12-08 and sora-2-pro-2025-10-06. There is no recommended replacement model — these are being discontinued, not migrated.
If you created work in Sora, OpenAI directs you to export it from sora.chatgpt.com/sunset, and says data associated with your use of Sora will be permanently deleted after any final export window passes. Purchased ChatGPT or Sora credits can still be used for Codex.
If you are choosing today: do not build on the Sora API. For generative video and design work the directory's surviving options are collected under the best AI design tools.
Gemini Code Assist — the free individual tier ended
This one produces the most stubborn wrong answers, because Google's own marketing pages were slower to update than its documentation. Per Google's deprecation notice, Gemini Code Assist consumer accounts were deprecated on May 18, 2026 and shut down on June 18, 2026. After that date the Gemini Code Assist IDE extensions and the Gemini CLI stopped serving requests for Google AI Pro and Ultra subscribers as well as for Gemini Code Assist for individuals, and those users were directed to Antigravity.
The old no-cost individual allowance, once a common recommendation for anyone wanting a free coding assistant, is historical. The product now ships in two editions, Standard and Enterprise, both managed through Google Cloud.
If you are choosing today: Gemini Code Assist is a paid product. If you came looking for a free assistant, compare against the free tiers that still exist in the best AI coding tools.
Galileo AI — now Google Stitch
Galileo AI's text-to-UI product is no longer reachable under its own name: usegalileo.ai now resolves to stitch.withgoogle.com, Google's design-to-code tool. We verified this redirect directly rather than inferring it from coverage.
If you are choosing today: the directory entry is retired and the URL redirects to the best AI design tools.
What we changed in the directory
We do not leave dead entries up. Each of these products was removed from the listings, and every URL it previously occupied — its tool page and every head-to-head comparison it appeared in — was given a permanent redirect to the closest surviving answer, so an old link lands somewhere useful instead of on a 404.
That is also why one stack disappeared. The Efficiency Stack was Supermaven plus Cursor; with Supermaven gone it would have been a list of one, so it was dropped rather than published as a stack with a single tool in it.
The dates on this page are the vendors' own. Where we could only verify a redirect rather than an announcement, we say so.
