an independent R&D lab building systems software, runtimes, developer tools, application platforms, and experimental computing platforms.

Write once. Target desktop, terminal, web, browser extensions, mobile, and embedded systems.

Crepuscularity combines React-style development with native rendering across GPUI, Ratatui, SwiftUI, Jetpack Compose, MV3 extensions, LVGL, and the web with a Rust, Javascript or Swift backend.

(i'll be big one day! :))

Projects built on Crepuscularity:

• Aurorality — native Apple platform tooling and SwiftUI generation
• rs_vimium — Vimium reimagined in Rust
• Anywhere — interactive AI-generated interfaces and artifacts
• Drift — the macOS screensaver as your wallpaper
• Mono — distributed application platform (coming soon)

Cross-language interoperability without glue code.

Load any C-compiling language from any other C-compiling language while preserving native developer workflows.

Projects:

• EqSwift — Rust ↔ Swift interoperability

A hyperlightweight musl+LLVM Linux distribution. Boots in less than a second, smaller than an average image taken on a phone.

Alpenglow supports two deployment modes: an immutable initramfs-only appliance mode with a RAM root and GlowFS overlay, and a normal rootfs mode for package-managed systems.

Projects:

• Soliloquy — immutable web-native operating system

A browser engine combining Servo rendering with the V8 JavaScript engine.

A capability-aware compiler pipeline (with support for multiple frontends) and orchestration language for deterministic execution, distributed systems, and agent-native software.

Projects:

• Space — post-POSIX operating system where components, capabilities, and execution graphs replace processes and syscalls
• Subspace — statically composed capability-safe embedded operating system

A pure Rust agent harness engine. Hosts embed it for the agent loop, tools, providers, sessions, permissions, computer-use, and IPC while retaining product and scheduling policy.

A local-first Rust AI agent runtime built on Rotary and ZKR. ~14MB binary, async-first (tokio), trait-driven. Ships with 10+ messaging channels (Telegram, Discord, Slack, WhatsApp, Matrix, Signal, IRC, Google Chat, MS Teams), 20+ LLM providers, pluggable memory with SurrealDB + RocksDB, tool guardrails with loop detection, streaming tool-call parsing, autonomous coding mode that runs 24/7 and only commits on passing tests, and a JSON-RPC plugin system with lifecycle hooks. Hot-reloadable tools, skills, and system prompt. Self-update via git poll + rebuild.

A hyperminimal UI runtime for the web. Bun-first, signals at the core, everything else an import. No metaframework lock-in — bring your own host (Vite, Waku, Next, Astro, Remix, Nuxt, TanStack Start) through thin re-export packages. Author in .tsx, or compile .crepus into moonshine for a lighter DSL. Inspired by Solid's signals, Svelte's approachability, and Waku's lightness.

Evidence-backed temporal memory engine for personal agents. Gives agents persistent, verifiable memory with temporal context.

Provider-neutral, verified computer-use execution for Rust.

Fast homebrew-compatible package manager in Rust. Uses Homebrew's ecosystem (formulae, bottles, casks) without the Ruby/Git overhead — compiled, async, parallel installs, lockfiles.

An open-source, local-first peer-to-peer social chat network with wallet identity, private encrypted messaging, and no central message store.
