Your terminal. Your IDE. Your browser.
One autonomous
engineering team.
CodeSync is the agent. It plans, writes, tests and debugs on its own, with 71 built-in tools, a local code graph and any of 90 models. When another agent fits a task better, it brings in Claude Code, Codex, Devin or Grok Build and shepherds them to the finish. Your keys, no lock-in, no token markup.
Multi-agent orchestration, permission guardrails, and ephemeral VMs on AWS, GCP, Docker, or your own hardware.
Built for teams who ship,
not teams who rent AI.
Most AI coding products lock you into one model, mark up your tokens, and run code on their infrastructure. DevsHub is the opposite.
The problem
Single-vendor agents. Opaque pricing. Production credentials on someone else's cloud. You pay a seat fee and a token markup.
The problem
IDE copilots autocomplete lines. They don't run your test suite, open a PR, or coordinate a multi-file migration across repos.
The problem
Autonomous agents without guardrails blow budgets and touch files you never approved. Teams need PLAN before CODE, not YOLO by default.
Autonomous workflows
Agents plan, edit, test, and iterate across your repos, not just suggest the next line. Pair on complex work or dispatch one-shot jobs that run to completion in a sandbox.
Any model. Your keys.
Route tasks across Anthropic, OpenAI, Google, and Ollama. Opus for architecture, Flash for batch refactors, local models for sensitive code. You pay providers directly. DevsHub charges for orchestration, not tokens.
Sandboxed execution
Sessions run in ephemeral Docker or cloud VMs. Credentials stay on your machine and inject on demand. Five permission levels from read-only PLAN to full CODE: you control what agents can touch.
Three steps to your first agent
Invite-only for now. Once approved, you're running in under a minute.
Connect your workspace
Quick setup links your project to the DevsHub control plane. Credentials stay local; sandboxes spin up on demand.
Run agents
Start an interactive session or fire a one-shot task. Agents edit files, run tests, and use tools inside your sandbox.
What takes days
takes an afternoon.
PR review at scale
Agent reads the diff, checks against your style guide via skills, runs affected tests, and leaves structured review comments.
Before: 45 min per PR → After: 5 min human review
Framework migrations
Parallel agents refactor deprecated APIs, update configs, and fix broken imports across a monorepo, with PLAN mode first, CODE mode after approval.
Before: 6-week epic → After: days with agent assist
Test generation
Point an agent at uncovered modules. It writes unit and integration tests, runs them in a sandbox, and iterates until green.
Before: Backlog forever → After: coverage in one session
Incident response
One-shot mode: paste the stack trace, agent traces the failure, proposes a patch, runs regression tests, and opens a branch.
Before: 2am pager duty → After: agent drafts the fix
Everything in one stack
PLAN · CODE · ASK modes
Strict permission boundaries. Read-only analysis before write access. Interactive Q&A without touching files.
MCP + Skills
Connect any MCP server. Install community skills from the registry: Chrome DevTools, Cloudflare, databases, and more.
Session resume & checkpoints
Pick up where you left off. Rewind conversation and workspace state to any checkpoint.
Multi-agent orchestration
Supervisor-worker patterns, parallel fan-out, and specialized sub-agents with their own models and tools.
Cost tracking
Per-session token usage and spend. Restrictive guards prevent agents from silently upgrading to expensive models.
Integrations via MCP
Extend agents with MCP wrappers for GitHub, Linear, Slack, and internal APIs: composable, not locked in.
They are agents. CodeSync is the agent that runs them.
CodeSync does the work itself, on any model. When Claude Code, Codex, Devin, Antigravity or Grok Build fits a task better, it starts them, keeps their sessions open and brings every result back.

Full comparison and sources →Your credentials never leave your machine
DevsHub isolates execution in ephemeral sandboxes. The control plane orchestrates state. It does not store your source code.
- Local credential injection: AWS profiles, GCP keys, and SSH credentials stay on your developer machine. Injected into sandboxes on demand.
- Ephemeral VMs: Workspaces spin up on demand and tear down when done. Docker, AWS, GCP, or Kubernetes targets.
- Execution policies: Command allow/deny lists and permission levels enforced before any tool runs.
- BYOC & air-gap: Self-host the control plane for regulated environments.
Every model. Zero token markup.
Route Opus for hard problems, Flash for batch work, Ollama for sensitive code. You pay your AI provider directly.
Other platforms charge $500–$2,000/seat/month and mark up tokens 30–300%. DevsHub charges for orchestration. You pay providers at cost.
The agent IDE.
Same engine as the CLI.
DevsHub IDE is a standalone editor experience built on VS Code. Open your repo, run agents in the integrated terminal, review inline diffs, and keep full workspace context, without switching to a separate copilot product.
Under the hood it is the same CodeSync agent you use from the shell: PLAN/CODE/ASK modes, MCP tools, session resume, and your API keys. The IDE adds selection injection, diagnostics, and blocking diff review on top of that stack.
- Inline diffs: agents propose edits; you accept or reject in the editor before anything lands on disk.
- Live workspace bridge: selection, open files, and diagnostics flow into the agent each turn.
- VS Code compatible: works in VS Code, Cursor, Windsurf, and Insiders, one install path.
