Description

Agentastic.dev serves as a comprehensive macOS development environment tailored for software engineers who utilize AI coding agents. By integrating an editor, terminal, browser, Git functionalities, and agent sessions, it enables users to deploy multiple coding agents while effectively isolating tasks within Git worktrees or containers. Developers can examine code differences, execute code review processes, test their applications using the integrated browser, and initiate work based on prompts, specifications, or relevant issues from collaborative tools. Moreover, the platform features a broad selection of command-line tools for coding agents and supports the development of custom terminal-based agents. The workspace can function on local machines, SSH-accessible development systems, or within compatible cloud platforms. Additionally, an iPhone companion app provides users the capability to oversee sessions and respond to agents when they require input. The macOS application is offered at no cost, while subscriptions and API usage for third-party agents incur fees payable to those providers, ensuring a flexible pricing model for various development needs. This innovative approach not only streamlines the coding process but also enhances collaboration among developers.

Description

Muse Code is a beta terminal coding agent from Meta designed to help developers complete complex software engineering work across large codebases. Powered by Muse Spark 1.2, the agent can plan repository changes, write code, run validation steps, and coordinate persistent subagents for difficult development tasks. Muse Code uses a simple main agent loop supported by async background agents that remain active throughout each session. These background agents can gather information, carry out next steps, and decide when to report back to the main agent, reducing latency and unnecessary user steering. The runtime is built around a local event log where every model call, tool run, approval, and edit is appended. This event log makes Muse Code replay-exact and restart-safe, allowing it to resume from the point of failure after a crash. Muse Code also ships with default skills, including /plan, /grill, and /goal, to support structured planning, plan validation, and objective completion. It can be installed on macOS or Linux and is integrated with Meta’s AI developer ecosystem. By combining terminal-based coding, persistent subagents, replay-safe execution, bundled skills, and Muse Spark 1.2, Muse Code helps developers automate larger and longer software engineering workflows.
