AddContainer and virtualization tools
linuxcontainers.org is the umbrella project behind Incus, LXC, LXCFS, Distrobuilder and more.
The goal is to offer a distro and vendor neutral environment for the development of Linux container technologies.
Our focus is providing containers and virtual machines that run full Linux systems. While VMs supply a complete environment, system containers offer an environment as close as possible to the one you'd get from a VM, but without the overhead that comes with running a separate kernel and simulating all the hardware.
AI → JSON → UI. AI-generated UI with guardrails.
When users prompt for UI, you need guarantees. json-render gives AI a constrained vocabulary so output is always predictable.
Predictable. Guardrailed. Fast.
Let users generate dashboards, widgets, apps, and data visualizations from prompts — safely constrained to components you define.

Your private note-taking app.
A self-hosted markdown editor with live preview, document encryption, multi-user support, and multi-organization capabilities.
Terraform provides a common configuration to launch infrastructure — from physical and virtual servers to email and DNS providers. Once launched, Terraform safely and efficiently changes infrastructure as the configuration is evolved.
Terraform enables you to safely and predictably create, change, and improve infrastructure. It is a source-available tool that codifies APIs into declarative configuration files that can be shared amongst team members, treated as code, edited, reviewed, and versioned.

declarative web crawling with XPath.
wxpath is a declarative web crawler where traversal is expressed directly in XPath. Instead of writing imperative crawl loops, wxpath lets you describe what to follow and what to extract in a single expression. wxpath executes that expression concurrently, breadth-first-ish, and streams results as they are discovered.
MCP OAuth Proxy incl. dynamic client registration (DCR), MCP prompt analytics and MCP firewall to build enterprise grade MCP servers.
Jetski is an Open Source MCP Analytics and Authentication Platform - part of HyprMCP. It solves the three biggest problems teams face when developing MCP servers with zero code changes:
Keeps your Claude session warm for you.
Stop paying to rebuild your Claude Code cache. When your main agent waits on a subagent for more than 5 minutes, its prompt cache silently expires, and the next turn re-encodes your entire conversation at the write rate instead of reading it back cheap. On long sessions with many subagents that's roughly 20% of your bill. claude-thermos keeps the cache warm so you never pay that tax.
Semantic Versioning for Nix Flakes.
Thaw works by operating directly on the ref specified for your flake's inputs. If a ref exists on the input and is a valid SemVer version, thaw will attempt to upgrade it to the latest version. Both url querey param and object configuration syntax are supported.
By default, non-major upgrades are allowed, but this can be changed with the --major flag. No additional tools or components are required.
Rapidly build AI apps in Python.

Sync for modern apps. The standard sync layer for local-first apps. Build reactive, realtime, local-first apps directly on Postgres.
ElectricSQL is a local-first software platform that makes it easy to develop high-quality, modern apps with instant reactivity, realtime multi-user collaboration and conflict-free offline support.
Local-first is a new development paradigm where your app code talks directly to an embedded local database and data syncs in the background via active-active database replication. Because the app code talks directly to a local database, apps feel instant. Because data syncs in the background via active-active replication it naturally supports multi-user collaboration and conflict-free offline.
