Show HN: Closedloop – isolated, temporary email for closed groups, on your cloud
Closedloop offers an isolated, air‑gapped communication workspace that runs on a user’s own cloud account. The service allows only invited participants to exchange messages, with no inbound or outbound traffic permitted by design. It is sold as a one‑time €49 fee, after which users pay the cloud provider directly for compute and can destroy the server at any time.
- ▪Closedloop deploys a sealed, webmail‑like workspace into the customer’s cloud environment such as Hetzner, DigitalOcean, Linode, or Vultr.
- ▪Communication is restricted to invited members and enforced at the firewall level, preventing any external data flow.
- ▪The workspace can be terminated and all data erased whenever the user decides, making it disposable by design.
- ▪Pricing consists of a €49 one‑time platform fee paid via Stripe, with no recurring subscription charges.
