Developer preview Hammerhead 0.2.0-dev

Historical engraving of Iguanodon and Megalosaurus interpretations; not a depiction of Talarurus. — Historical Iguanodon and Megalosaurus engraving. E. Ferington after Édouard Riou, [1863]. Wellcome Collection.

Mission

Talarurus builds software that is clear,
useful, and easy to trust.

Hammerhead Core / 0.2.0-core.1 prerelease

Look closer.
Before you run it.

Hammerhead Core offers six filesystem checks with terminal and JSON reports. GIT-002 is NOT EVALUATED; native Git execution is absent. The macOS ARM64 prerelease is experimental, unsigned, unnotarized and Gatekeeper-unqualified; tested only on macOS 27.0.1 ARM64.

Areas of work

Security, development,
and local control.

Three areas guide the studio’s work, starting with repository security.

Security

Tools that help you inspect software and make more informed decisions.

Developer tools

Focused utilities with clear output that fits into existing workflows.

Local-first software

Software designed to keep work close to your own machine and data.

How the studio builds

Focused tools.
Defined boundaries.

Talarurus develops software around specific tasks, with explicit limits on what each tool can do.

Hammerhead’s documentation covers its supported checks, reporting formats, and limitations. Its 0.2.0-dev preview is available to build from pinned source.
