Octelium
A next-gen FOSS self-hosted unified zero trust secure access platform
Octelium is an open source, self-hosted unified secure-access platform built for modern infrastructure and hybrid environments. It positions itself as more than a typical VPN; it supports zero-trust network access (ZTNA), “BeyondCorp”-style access, API/AI gateway functionality, and even serves as a PaaS-like deployment surface. One of its key strengths is identity-based, application-layer (L7) aware control, meaning access decisions are made per request, with context and policy rather than simple network-level allow/block rules. It supports both client-based (e.g., WireGuard/QUIC tunnels) and client-less access models, which makes it flexible for both human users and automated workloads. The project also highlights self-hosted, no hidden “server-side” locked components, giving organizations greater ownership and control over access, rather than relying on proprietary SaaS. -

Shuttle
Build & ship backends without writing any infrastructure files
Shuttle is a Rust-focused backend deployment platform designed to help developers build and ship applications without writing infrastructure configuration files. It lets projects provision resources such as databases directly from application code, removing the need for separate YAML or cloud setup workflows. The platform supports fast development by combining project initialization, resource provisioning, and deployment into a streamlined CLI experience. It works with popular Rust web frameworks such as Axum, Actix Web, and Rocket. Shuttle also handles infrastructure concerns like permissions and security so developers can focus on application logic. Its repository includes the Shuttle CLI, runtime, services, resource integrations, examples, and deployment-related tooling. The GitHub repository is currently archived and read-only, but it remains a useful reference for the platform’s architecture and Rust deployment model. -
