Atsign introduces NoPorts Personal free tier
Atsign introduced NoPorts Personal, a free-forever tier of its networking software for personal and non-commercial use and said it addressed Network Address Translation (NAT) obstacles and the risk of open ports that affect hobbyists, students, and prosumers.
The company made the same technology it used for securing critical infrastructure and for building guardrails for Enterprise Artificial Intelligence (AI) deployments available at no cost and described the release as targeted at Home Lab users seeking safer remote access.
NoPorts does not bridge networks or create tunnels; it connects particular devices and applications by cryptographic identity and uses End-to-End Encryption (E2EE) with keys generated and stored only on the endpoint. The service acts as an outbound-initiated architecture with full bidirectional data flow, and Atsign and NoPorts never possess those keys.
The free tier allowed connections to up to two devices and was available immediately for download at www.NoPorts.com. The release listed supported uses such as access to Large Language Model (LLM) interfaces like Ollama and Open WebUI on NVIDIA RTX 3090/4090 rigs, remote reach to Plex, Jellyfin, and Home Assistant instances, and operation on hardware from Raspberry Photonic Interposer (PI) clusters to Intel NUCs and Dell PowerEdge systems running Proxmox or ESXi.
“We believe that the techies running Kubernetes clusters at home today are the ones who will architect the secure enterprise clouds of tomorrow,” said Colin Constable, CTO and Co-founder of Atsign. “They deserve the same world-class security that protects critical utilities and sovereign AI deployments. With NoPorts Personal, we are eliminating the open port, instantly encrypting cleartext protocols like HTTP, MQTT, or MCP, and giving data sovereignty back to the individual.”
The release described the atPlatform as removing the need for open ports and centralized servers and as enabling applications with “invisible” security while placing data and device control back into the hands of their owners.
