Features

Everything you need to orchestrate AI agents

A purpose-built workspace that turns chaotic multi-agent workflows into a controlled, reviewable process.

Parallel Execution

Run dozens of agents at once

Launch multiple AI coding agents across different tasks simultaneously. Each agent gets its own isolated environment, and you can monitor all of them in real time.

Concurrent task execution across agents
Real-time progress tracking and status
Automatic resource management

Isolation

Changes stay isolated

Every agent runs in its own Git worktree. No merge conflicts, no stepping on each other's changes. Merge when you're ready, not when the agent decides.

Automatic Git worktree creation
Zero-conflict parallel development
Clean merge paths to main

Each agent works in complete isolation - zero conflicts

IDE Integration

Open in any editor

One-click deep links into VS Code, Cursor, JetBrains, Xcode, or any editor you prefer. Review and edit agent-generated code in your native environment.

Code Review

Review changes with clarity

See exactly what each agent changed. File-level diffs, line counts, and approval workflows give you full control before anything touches your main branch.

Per-agent file diffs and change summaries

Ideas on the future of agentic development

Thoughts on architecture, workflows, and the evolving landscape of AI-powered engineering.

Engineering

Why parallel agent execution changes everything

Running agents concurrently vs sequentially isn't just faster - it fundamentally changes how teams decompose work. We break down the throughput gains and the orchestration challenges.

Architecture

Git worktree isolation: how Phasr prevents agents from colliding

Containers are heavy. Branches alone aren't enough. Worktree-based sandboxing gives each agent a clean, isolated copy of your repo without the overhead.

From prompt to PR: designing a human-in-the-loop review pipeline

Real-time diffs, inline annotations, and one-click approvals. How we built a review flow that keeps humans in control without slowing agents down.

The multi-model future: why agent orchestration should be provider-agnostic

Different models excel at different tasks. Your orchestration layer shouldn't lock you into one provider - it should let you use the best tool for each job.
