The first multiplayer AI code editor. Now with Share Chat.
Dropstone is the first multiplayer AI workspace. v3.0.5 adds Share Chat: send a link to code with humans & agents in real-time. Features infinite context (D3 Engine), persistent memory & background swarms. Built on original research, not a wrapper.
Hi Product Hunt! 👋 I’m one of the makers at Blankline (the research lab behind Dropstone).
We noticed a critical problem with tools like Cursor and Claude Code: They are single-player. You code alone. If you get stuck, you paste snippets into Slack. If you're a founder hitting the "70% wall," you're stranded.
Dropstone 3 is the first multiplayer AI workspace. With today's release, we are launching Share Chat:
🔗 One Link: Generate a URL for your local workspace.
⚡ Instant Join: A senior dev, designer, or client joins instantly.
🧠 Shared Brain: Everyone shares the same AI context and live preview.
This is not a wrapper. We are a research lab building proprietary infrastructure:
D3 Engine: Virtualizes context (50:1 compression) for infinite memory.
Horizon Mode: Background agent swarms that fix bugs asynchronously while you sleep.
We’re live in the comments to answer questions about our compression architecture or the "70% wall." Let us know what you think! 👇
