Flowise
Open-source (Apache 2.0) visual builder for LLM apps and agents, self-hostable. On July 29, 2026 the team announced the shutdown and a code freeze; the FlowiseAI/Flowise repository was archived on August 10, 2026. The August 31, 2026 end-of-life meant the core team left Discord and GitHub support. The code remains public and the team encourages forks.
Company wind-down — the team says developers moved from rigid low-code workflows to coding agents (Claude Code/OpenClaw).
No honest successorThe Flowise team left the category. An unofficial community fork exists (dblagbro/flow-wiser, unvetted), but coding agents ate the use case.

Void
Open-source Cursor-like editor, local-first, bring-your-own-model. It was technically notable for mounting React and Tailwind inside a VS Code fork and for its packaging and auto-update pipeline. The archived README now pitches the codebase as a reference for anyone forking VS Code. There is no official successor; voideditor.com lists community forks.
Deprecated by Glass Devtools — the repository was archived on June 2, 2026 and is no longer accepting contributions.
No honest successorNo official successor. Community forks are listed on voideditor.com.

Roo Code
Open-source VS Code extension in the Cline lineage, with modes (Code, Architect, Ask, Debug), MCP support, and bring-your-own-model routing. The extension shut down on May 15, 2026 and the repository was archived. The README now points users to ZooCode as a community fork and to Cline as the upstream open option.
Roo Code Inc shut down the VS Code extension (plus Roo Code Cloud and Router) and pivoted to a cloud agent.
Succeeded by → RoomoteBy the same team (roomote.dev states "By the creators of Roo Code"). The extension's community continues as ZooCode.

Sora
OpenAI's text-to-video model launched publicly in December 2024, followed by Sora 2 and a social app in 2025. On April 26, 2026 the web app and mobile app were discontinued with data export offered to users. The API lived on as a legacy service for existing accounts (sora-2 $0.10/sec at 720p, sora-2-pro up to $0.70/sec at 1080p) until September 24, 2026. No successor was announced.
OpenAI discontinued the Sora web app and API — the generative video product that made text-to-video mainstream.
No honest successorOpenAI announced no successor. The API itself dies 2026-09-24; video buyers moved to Veo, Runway, Kling and Seedance.

Play.ht
A TTS API and voice library that once mattered. Meta acquihired the team and the platform closed on 2025-12-31 — accounts, saved audio and voice clones deleted, no migration path offered. Sites still taking payments as "Play.ht" are impersonators.
Team acquihired by Meta (July 2025); platform shut down permanently.
Succeeded by → Inworld TTSInworld published the PlayHT → Realtime TTS migration path after Meta's acquihire. Clones were deleted — you reclone from original audio, there is no transfer. Not a Noemium card. If you wanted Play.ht for studio dubbing or a huge voice library, ElevenLabs is the in-catalog default (Inworld says so too).

Supermaven
Speed-focused code completion by Jacob Jackson (Tabnine creator), built around the Babble model with large context and plugins for VS Code, JetBrains and Neovim. Anysphere acquired Supermaven on November 12, 2024, initially promising the plugins would stay. The product was officially sunset on November 21, 2025: prorated refunds were issued, agent conversations were turned off, VS Code users were pushed to Cursor, and only legacy free autocomplete remained for existing Neovim and JetBrains users.
Sunset by Anysphere one year after acquisition to consolidate users and technology into Cursor Tab.
Succeeded by → CursorCursor absorbed the team and the speed work into Cursor Tab. In the catalog.

Woebot
CBT-based mental-health chatbot since 2017, reaching roughly 1.5M users. The consumer app was retired on June 30, 2025: sign-ups and account access were disabled, transcripts were available only until July 15, and data was anonymized by July 31. The company continues licensing the technology to enterprises, but the public bot is dead.
Woebot Health retired the consumer app — FDA marketing-authorization costs and LLM-in-therapy uncertainty made the direct-to-consumer model unsustainable.
No honest successorThe company licenses the tech to employers and health systems; the consumer bot you could talk to is gone.

Tome
AI-native presentation tool that reached roughly 20M users at its peak. In 2024 the company pivoted toward sales use cases. Tome Slides shut down on April 30, 2025 — sign-in was disabled and unexported decks were permanently deleted. The founders subsequently launched Lightfield, an AI-native CRM.
The team shut down Tome Slides after failing to make AI presentations a business, pivoting to an AI-native CRM.
No honest successorNo presentation successor — the team left the category entirely for CRM (Lightfield). A different company named Tome (legal AI) was bought by AngelList; do not confuse them.

Humane AI Pin
$699 wearable AI device launched April 2024 to replace smartphones. HP acquired the Cosmos platform plus roughly 300 patents for $116M, announced February 18, 2025. Services shut down February 28, 2025, all user data in Humane Center was deleted, and remaining devices were left with only offline battery checks.
HP acquihired the company for its Cosmos AI platform, patents and talent, then sunset the AI Pin hardware and services.
No honest successorThe team and IP went inside HP as the HP IQ lab. No consumer successor — the buyers wanted the platform, not the pin.

Skiff
Privacy-first, end-to-end-encrypted email, documents and calendar. Notion acquired Skiff on February 9, 2024. All services shut down on August 9, 2024 (email forwarding continued until February 9, 2025). Accounts did not convert; users had to export data manually or lose it. The team's technology later fed Notion Mail.
Acquired by Notion in February 2024 and sunset as a standalone product.

AI-personalized news app from Instagram co-founders Kevin Systrom and Mike Krieger, launched in 2023. The market was deemed too small by January 2024. Yahoo acquired the company and the standalone app ceased operation on April 2, 2024; posts and comments were already disabled and the product was folded into Yahoo properties.
Acquired by Yahoo, which shut down the standalone app and absorbed the personalization tech into Yahoo News.

The standalone Windows app was disabled in early August 2023 with a deprecation notice.

Galactica
Meta AI / Papers with Code science LLM, launched November 15, 2022. Within hours users found fake citations and fictional papers delivered with high confidence. Meta paused the public demo on November 17, 2022 and never restored it. The weights and code remained available to researchers.
Meta paused the public demo after researchers showed it generated plausible but false scientific text and fabricated citations.

Kite
Local AI code completion for Python and JavaScript inside VS Code and PyCharm, reaching roughly 500k monthly active users but generating little revenue — developers would not pay. Affirm bought the technology, IP and part of the team for about $25M in June 2021. On November 16, 2022 founder Adam Smith announced the end of work and support. The codebase was open-sourced; the commercial product died.
Acquihired by Affirm in June 2021, then sunset in November 2022 after failing to monetize 500k monthly developers.
No honest successorThe code went open source; the business went nowhere. Its lesson — developers don't pay for autocomplete — was later disproven at scale by Copilot and Cursor.
