They are agents.
CodeSync is the agent that runs them.

CodeSync is an agent first: it plans, edits, tests and debugs itself, with 71 tools, a local code graph and any of 90 models. When Claude Code, Codex, Devin or Grok Build fits a job better, it starts them, keeps their sessions open, answers what they ask and brings every result home.

A superset, not a substitute

You do not have to pick a winner. Keep the agents your team already likes and put CodeSync above them.

Shepherd any agent

Start @claude, @codex, @devin, @grok and eight more, keep each session open, steer them mid-run, and collect every result in one place.

Bring your history

Pull existing Claude Code, Codex, Gemini, Cursor, Aider, Grok, OpenClaw and Antigravity sessions into CodeSync and keep going where you left off.

Keep your MCP servers

One command reads the MCP config of 13 agents and IDEs, including all five here, so your tools come along without retyping a line of JSON.

Use what you pay for

Delegation runs each vendor's official CLI signed in as you, so the plans you already pay for keep working. Add API keys or local models for everything else.

It works alone. It also leads a team.

CodeSync does the work itself. When it brings in another agent, it does not send a prompt and hope; it stays with that agent for the whole job: it opens the session, keeps it alive, answers what the agent asks, notices when it stalls, and brings the result home.

Fig. 3. Shepherding four live sessions. Example timeline, illustrative.

Start

Opens the agent's own CLI, installing it first if it is missing.

spawn @codex

Keep

Holds a live, multi-turn session instead of a one-shot call.

session/new · session/load

Watch

Tracks every agent's heartbeat and flags one that goes silent for 90 seconds.

status · list

Gate

When an agent asks to write a file or run a command, CodeSync answers within your own permission level: allow once, allow the tool, or deny.

permit

Steer

Sends follow-ups mid-run, cancels a turn, or stops the agent.

send · cancel · kill

Attach

Opens a live view of any running agent from another terminal.

/agents attach

Resume

Picks an interrupted multi-agent run back up from its finished steps.

resume

Herd

Runs several agents as a team: in sequence, in parallel, as a pipeline, a debate, a hierarchy, or map-reduce.

collaborate

Live sessions run over the Agent Client Protocol with Claude Code, Codex, Devin and Grok Build (plus OpenCode, OpenClaw and Hermes). Antigravity and the other CLIs are dispatched one task at a time.

"Not in docs" means we searched the vendor's full public docs index on 8 November 2026 and did not find the feature. Scroll the table sideways on small screens.

Each of these is a strong agent. Here is what changes when CodeSync sits above it.

CodeSync vs Claude Code

Where it shines: a deep Claude-native loop with subagents, hooks, plugins and cloud scheduled tasks.

+CodeSync opens a live @claude session, answers its permission requests and sends it follow-ups, next to Codex or a local model.
+Not tied to Claude: 90 models across 14 providers, including GPT, Gemini, Grok and local.
+A local code graph for impact analysis, instead of grep alone.
+Secrets are masked before the model sees them.

$ codesync session import --agent claude --pick

CodeSync vs Codex

Where it shines: OpenAI models included with ChatGPT plans, local models via --oss, and an import flow from Claude Code and Cursor.

+Keeps a live @codex session on your ChatGPT plan, and flags it if it stops responding for 90 seconds.
+Imports full sessions, not only setup, from 8 agents.
+Multi-vendor debate rooms instead of single-vendor subagents.
+Watches that cost nothing to check, and reach you on WhatsApp or Telegram.

$ codesync session import --agent codex --pick

CodeSync vs Devin

Where it shines: cloud sessions, DeepWiki, Slack, Teams and Jira, plus the Adaptive and Fusion model routers.

+Your code graph is built and kept on your machine, not in a hosted index.
+Pay providers at cost with your own keys, or run local models.
+Holds a live @devin session for the work it is best at, steerable mid-run, while everything else stays local.
+Six-vendor debate rooms, beyond a two-model lead and sidekick.

$ codesync agents import-mcp --from devin

CodeSync vs Antigravity

Where it shines: a Gemini-first agent IDE and CLI with browser-in-the-loop checks, voice mode and a free tier.

+Dispatches Antigravity as @agy task by task, and imports the sessions you already have.
+Imports MCP servers from 13 tools; Antigravity documents none.
+Event watches and chat-app access, neither of which is in its docs.
+GPT, Grok, Kimi, DeepSeek and more, beyond its curated list.

$ codesync session import --agent agy --pick

CodeSync vs Grok Build

Where it shines: an open-source (Apache 2.0) terminal agent with subagents, background monitors, bring-your-own model endpoints, and a reader for Claude and Cursor MCP configs.

+Keeps a live @grok session alongside Claude, Codex and the rest, and answers its permission requests within your own permission level.
+90 models across 14 providers ready to use, with no endpoints to configure by hand.
+Watches checked by code at no model cost, where each scheduled Grok prompt runs a full agent turn.
+Imports sessions from 8 agents and MCP servers from 13 tools, beyond Claude Code and Cursor.

$ codesync session import --agent grok --pick

Bring everything in three commands

Sessions, MCP servers and the agents themselves. Nothing to uninstall.

Method. CodeSync figures are counted from its source on 8 November 2026: drivable agents from the external-agent registry, models and providers from the model registry, MCP import sources from the importer's parser table. Watches are evaluated by plain code; a model is called only when a watch fires.

What we left out. Rows where a competitor matches CodeSync (terminal, IDE and web surfaces, automatic model routing, browser control) are not listed. We measured our code graph's lookup speed against plain grep and it was slower, so we make no speed claim.
