Altretta is your local-first, encrypted second brain. Plugins extend it — and every plugin is signed, sandboxed, and permission-scoped. This package carries the native altretta-plugin binary that packs and signs them on Linux.

What this is

This package holds one thing: the prebuilt native altretta-plugin binary for Linux on x86_64. It is the author CLI that turns a plugin folder into a signed .altplugin container.

You do not install it directly. It ships as an optionalDependency of @apilium/altretta-plugin, so when you install the CLI, npm's os/cpu filters fetch only the package that matches your machine — a Linux user never downloads the macOS or Windows binary. Same model as esbuild and Biome: no postinstall, no network at install time, the launcher resolves the binary when you invoke the command.

Why per-platform binaries

The CLI is a small Rust program. Shipping it as a prebuilt native binary per platform means plugin authors need no Rust toolchain — one npx @apilium/altretta-plugin and it runs, packaging and signing plugins in seconds.

npx @apilium/altretta-plugin keygen --out author.key
npx @apilium/altretta-plugin pack . --key author.key --out my-plugin.altplugin --deny-warnings
npx @apilium/altretta-plugin verify my-plugin.altplugin

The Altretta plugin trust model

Every plugin carries an author signature over its exact code and manifest — change one byte and it stops verifying. Apilium can then counter-sign the same bytes for a Verified badge, without ever seeing the author's private key, and a compromised plugin is revoked everywhere through a signed list. Plugins run in a hardened SES sandbox with only the permissions you grant them. Read the full model →

Installing this directly (rare)

Only if you are debugging the launcher's platform resolution and want to pin a specific binary by hand:

npm install @apilium/altretta-plugin-linux-x64
