// Agent profile
pacifio/atlas is source control built for the multi-agent coding era. Every agent run produces checkpoints: commits linked back to the session that made them alongside prompts, tool calls, and reasoning. Run Claude Code, Codex, or any agent from the ACP registry side by side against the same codebase with shared memory, so switching agents mid-task doesn't mean starting over. Atlas hit 3,000+ stars on GitHub and has been trending consistently since its May 2026 launch. Written in Rust, it runs local by default — code, notes, and sessions stay on your machine — with optional team sync via organizations. The shared memory layer means a decision Claude Code made shows up in Codex's next prompt, eliminating the cold-start problem that plagues multi-agent workflows.
Atlas is source control for coding agents from pacifio, currently at 3,000+ GitHub stars and climbing fast. The core insight is that agents now write a large share of code but keep none of the reasoning behind it. Atlas records both the changes and the reasoning, then makes them queryable: what changed, by whose agent, at what point in time, and why.
The differentiator is the checkpoint model. Every agent run produces a checkpoint that links a commit back to the full session — prompts, tool calls, file diffs, and reasoning. This is not just git history with extra metadata; it is a structured record that lets you trace any line of code back through the agent conversation that wrote it.
The second differentiator is shared memory across agents. Atlas maintains a persistent on-device memory index of decisions, plans, file changes, and architecture notes. When you switch from Claude Code to Codex mid-task, the new agent picks up context from the last one automatically. The semantic matching runs locally — your message is embedded on-device and matched against the project’s memory index every turn.
Atlas supports the Agent Client Protocol (ACP) from Zed, so any compatible agent can plug in. Claude Code and Codex run as external subprocesses over ACP. Atlas’s own built-in agent runs in-process on Cersei, their Rust agent framework.
Builder.io's open-source framework for building agent-native applications — shared actions, SQL-backed state, identity, tools, skills, jobs, observability, and UI surfaces that all work together.
CLI orchestration tool that installs and configures platform connectors for 16+ social and web sources — Twitter/X, Reddit, YouTube, GitHub, Bilibili, and more. Zero API fees.
Persistent memory layer for AI coding agents — benchmark-backed (95.2% on LongMemEval-S), 92% fewer tokens per session vs full-context pasting, zero manual memory.add() calls.
