Best AI Coding Agents for Mac of 2026 - Page 3

Plandex is an open source, terminal-based AI coding engine designed to assist users in efficiently completing extensive tasks, navigating around suboptimal outputs, and enhancing overall productivity. By utilizing long-running agents, it manages tasks that may involve multiple files and intricate procedures. The engine systematically divides larger assignments into manageable subtasks, executing each sequentially until the entire project is accomplished. This tool is particularly useful for tackling backlogs, exploring unfamiliar technologies, overcoming obstacles, and minimizing time spent on tedious tasks. Additionally, all modifications are stored in a secure sandbox environment, enabling you to review changes before they are automatically applied to your project files. With integrated version control, reverting to previous iterations and experimenting with different methodologies is straightforward. Furthermore, the branching feature allows users to explore various approaches simultaneously and assess their outcomes for better decision-making. By streamlining the coding process, Plandex empowers developers to focus on creative problem-solving rather than mundane details.

Auggie CLI seamlessly integrates Augment’s intelligent coding agent into your terminal, utilizing an advanced context engine to evaluate code, implement changes, and run tools in both interactive sessions and automated workflows. Developers can easily set it up through npm, which requires Node.js 22 or higher and a compatible shell, and they can initiate a full-screen interactive experience using the command auggie, featuring real-time updates, visual progress indicators, and conversational tools suitable for debugging, developing new features, reviewing pull requests, or managing alerts. Furthermore, Auggie provides optimized modes for automation that are perfect for continuous integration and deployment pipelines, as well as for handling background tasks. The CLI also facilitates the use of custom slash commands to streamline repeatable processes, integrates with various external tools and systems through native integrations and Model Context Protocol (MCP) servers, and can be scripted within pipelines or GitHub Actions for tasks such as automatically generating pull request descriptions. Ultimately, Auggie CLI revolutionizes the coding experience by combining intelligent assistance with robust automation capabilities.

Tonkotsu is a desktop application designed for developers to oversee a team of AI coding agents through a document-focused interface, facilitating a well-organized workflow for planning, coding, and verification that enhances software development by allowing numerous coding tasks to be executed simultaneously while ensuring human supervision and control. Within a single document, users can define the project’s direction and context, after which Tonkotsu evaluates codebases and formulates comprehensive plans; developers can then allocate and monitor a multitude of autonomous tasks without the need for micromanagement. Once the work is complete, teams have the ability to review differences, provide inline feedback, and approve modifications, benefiting from automatic processes for building, linting, testing, resolving conflicts, and merging to enhance the iteration process, guaranteeing that no commits are finalized without direct approval. Designed specifically for professional developers using macOS and Windows, Tonkotsu also allows for planning across various repositories, offers symbol lookup for maintaining context, enables task dependency specification to logically sequence work, and incorporates automatic verification features to improve overall accuracy in development. Additionally, the platform’s intuitive interface simplifies the collaboration between human developers and AI, fostering a more efficient development environment.

Claude Code Security is an AI-powered security solution integrated into Claude Code that helps organizations proactively defend their software from vulnerabilities. Unlike traditional static analysis tools that rely on predefined rules, it reasons through code the way a human security researcher would. By understanding business logic, tracing data flows, and examining component interactions, it detects subtle and high-severity vulnerabilities that automated scanners often miss. Every identified issue passes through a layered self-verification process in which the AI attempts to confirm or refute its own findings to minimize false positives. The system then assigns severity and confidence ratings so teams can focus on the most urgent threats. Within the security dashboard, developers can review detailed explanations and inspect AI-generated patch suggestions before making any changes. Human oversight remains central, as no fixes are applied automatically without approval. Built on Claude Opus 4.6, the technology has already uncovered hundreds of long-hidden vulnerabilities in open-source projects. The tool is being released as a limited research preview to Enterprise and Team customers, with expedited access for open-source maintainers. By equipping defenders with advanced AI-driven analysis, Claude Code Security aims to raise the overall security baseline across the software industry.
