mise is an open-source command-line tool for managing development tools, environment variables, and project tasks from a single mise.toml configuration file. It installs and switches between tools such as Node.js, Python, CMake, Terraform, Go, and jq, and prepares the configured environment before commands run. Project-specific environment variables can include values from .env files, while tasks define commands and dependencies for activities such as building, testing, linting, validation, and deployment.

jit is a local-first macOS command-line secrets manager from jitpass that moves development credentials from plaintext files such as .env, AWS credentials, shell exports, npm configuration, and MCP configurations into an encrypted vault protected by Touch ID. It rewrites source files with decoys so existing tools can continue working while the real value is released only to an authorized process. It provides credentials through per-process environment injection, native credential protocols such as AWS credential_process and Docker or Git credential helpers, and a named-pipe mount for tools that only read files. The named pipe is a mode-0600 POSIX FIFO: authorized reads receive decrypted values through the kernel pipe buffer without writing them to disk, while ambient readers receive decoys. jit is macOS-only for Apple Silicon and is still in development; the project states that it does not protect credentials after they enter the requesting process's memory.

A hosted application for compiling OpenProse programs, managing jobs defined by a contract and a trigger, and running event-driven multi-agent workflows. It can run declarative workflows written in plain Markdown, including jobs triggered by webhooks and pull requests.

djs is a small JavaScript and TypeScript engine written in no_std Rust and built mainly for WebAssembly. It runs codemode scripts, including model-written programs that call tools, process their results, and return data; the project describes it as a QuickJS replacement for pi's codemode. The virtual machine stores all state in one byte array addressed by 32-bit offsets, allowing a new VM to be created by copying a prebuilt image and allowing the host to read results directly from that memory. Its interpreter avoids using the Rust call stack for JavaScript calls, so execution can be suspended between instructions and resumed inside callbacks, getters, and asynchronous functions. A suspended tool call can be serialized as a continuation dump containing JavaScript code that recreates the run. A single compilation pass produces stack bytecode while erasing TypeScript during parsing, and clock, randomness, and weak references are supplied by the host so identical inputs produce byte-identical heaps in native and WebAssembly environments. djs is distributed as the @earendil-works/djs npm package and also provides a Rust CLI for running scripts, starting a REPL, and disassembling code. Its behavior is tested against dquickts, a QuickJS fork, and the repository includes documentation, architecture notes, testing instructions, and a pi codemode adapter.

blaze is an incremental Rust build tool that replaces selected Cargo commands, including build, check, run, test, and bench. Its daemon keeps the project compiled in memory; after an edit, it compiles only the changed functions and links the program with its own linker, enabling millisecond-scale rebuilds and live edits to a running program. It uses its own Rust toolchain and supports macOS on Apple silicon and Linux. The tool trades memory for speed, requires several gigabytes for a small project, and is distributed under the MIT or Apache-2.0 licenses.
