This GitHub repo turns Windows' built-in security controls into one open-source toolkit.

It's called Harden Windows Security.

Instead of installing another security engine, it uses supported Microsoft features already inside Windows. :contentReference[oaicite:0]{index=0}

→ Microsoft security baselines
→ Defender and attack surface reduction
→ BitLocker and Device Guard
→ Windows Firewall and exploit mitigations
→ App Control policy management
→ Security verification and scoring

The Harden System Security app has zero third-party libraries and zero telemetry. It supports x64 and ARM64, and installs from the Microsoft Store.

The repo is MIT licensed, has about 4.6K GitHub stars, and uses signed builds, SBOMs, and artifact attestations.

It's actively maintained too. Harden System Security v1.0.77.0 shipped on August 4, 2026.

Everyone keeps starring the same old GitHub repos. These 9 shipped in 2026 and most people haven't touched them yet.

No paywalls. No SDK wrappers with a pretty README. Just tools people actually keep open all day.

RIP ChatGPT for everything.

If ChatGPT is still your entire AI stack, you’re leaving a lot on the table.

Because the smartest AI users aren’t looking for one tool that does everything.

They’re using the ''best tool for each job.''

One developer got tired of managing mTLS certificates with shell scripts and OpenSSL.

So he built VaulTLS.

It turns TLS and SSH certificate management into a self-hosted web app.

→ Create and manage X.509 certificates
→ Manage SSH certificates
→ OIDC login support
→ Expiration email alerts
→ REST API for automation
→ ACME CA support for Traefik and https://t.co/LwQLDemmiA
→ Docker and Podman deployment
→ Import existing TLS CAs and certificates

The latest release also adds SSH revocation lists.

Built with Rust and Vue.js.

GPL-3.0 open source.

8. Hallmark

A design skill for Claude Code, Cursor, and Codex that fights generic AI-generated UI. It runs slop-test gates before handing back a design, so interfaces feel intentional instead of templated.
