Is Kosmik shutting down, and when will it stop working?

Updated

Yes. Kosmik is winding down, and the company states that the product will sunset on May 31, 2026. That date comes directly from the notice on the Kosmik homepage, which also says the team has been building Kosmik for the past 8 years.

If you currently use Kosmik, the practical takeaway is that you have until that sunset date to get your work out. The same notice points users to instructions for exporting their data, so exporting is the first thing to handle rather than waiting until the deadline approaches.

What the shutdown notice actually says

The homepage announcement is short and specific:

  • Kosmik is "winding down."
  • The service will sunset on May 31st 2026.
  • The team describes the decision as difficult and thanks users, investors, and the community.
  • Users are directed to a guide on how to export your data.
  • Users can reach the team by email or by booking a call for help, ideas, or feedback.

The notice also lists milestones from Kosmik's history, including a 2018 on-device IPFS node with multiplayer capabilities, a 2022 multiplayer web browser, and Kosmik 3 in 2025 with a built-in browser, auto-tagging, and AI search. None of that changes the shutdown timeline — it's context for what the product was, not a signal that development continues.

What this means if you use Kosmik

The notice does not say the app stops working earlier than the sunset date, so the reasonable assumption is that it remains available until May 31, 2026. It also does not describe what happens to accounts, canvases, or stored data after that date, which is exactly why exporting matters.

A sensible order of operations:

  1. Open Kosmik and review which canvases, boards, and libraries you actually need.
  2. Follow the export guide linked from the homepage notice to pull your data out.
  3. Verify the exported files open correctly outside Kosmik before you rely on them.
  4. If something is unclear — access problems, export issues, account questions — use the contact options in the notice (email or a booked call) while the team is still responding.

Common questions

Is there a replacement product? The notice says the team is "exploring several options to continue our work on spatial interfaces and document-oriented systems," but it does not announce a successor app or a migration path. Treat that as intent, not a product you can plan around.

Does the notice mention refunds or pricing changes? No. The homepage notice covers the shutdown date, data export, and contact options only. Any billing question would need to go through the team directly.

Where should I check for updates? The Kosmik homepage notice is the source for the sunset date and export guidance. If the timeline changes, that page is the place it would be reflected.
