Fletch is the IDE for agentic engineering, designed for macOS. It enables you to run AI coding agents in parallel under real isolation, chaining them into deterministic, specialist-driven workflows. These workflows cover planning, building, reviewing, and testing, ensuring you can ship AI-written code you can trust.

• Deterministic Workflows: Chain specialist agents (architect, coder, reviewer, tester) into a repeatable pipeline with a gate at every step. This ensures a disciplined process for every feature.
• Real Isolation: Each agent operates in its own full clone within a hard sandbox, preventing interference with your repository, machine, or other agents' work.
• User-Controlled Gate: Maintain control with live diffs, real reviews, and a single button to move from change to a merged PR. Nothing is landed until it clears your checks.
• Orchestrates Trusted Specialists: Fletch integrates with tools you already use, such as Greptile, your CI, and your test suite, conducting them as a single pipeline without replacing them.
• Local-First Approach: Your code remains in your Git repository, and agents utilize plans you already pay for. Fletch's servers do not access your source code.

Fletch provides a disciplined approach to AI-driven code development, moving beyond simple prompts to a structured, repeatable process. It ensures that AI-generated code is not just plentiful but also engineered and trustworthy. Download Fletch for macOS and start your first disciplined workflow in under a minute.
