Coder alternatives

Answer in brief

The 5 alternatives below are grouped by kind of sandbox, and each says what it does differently from Coder. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.

By the Agent Sandboxes editors · Updated

Why teams look beyond Coder

The leading open-source, self-hosted workspace platform for agents and developers, with isolation as strong as the Terraform templates you write.

  • Not a hosted service: you operate the control plane, provisioners and the infrastructure behind every workspace
  • Isolation, startup time and persistence all depend on your templates rather than being guaranteed by Coder
  • Premium pricing is not published; agent counts are capped at 5 below the AI Premium tier
  • Coder Tasks was removed, so older agent integrations need migrating to Coder Agents

Coder alternatives, by kind

Hosted sandbox platforms

SDK-driven sandboxes you create, run code in and destroy through an API.

  • Daytona

    Stateful sandboxes for AI-generated code — Linux containers, Linux and Windows VMs, macOS and GPU sandboxes — with snapshots, volumes and preview URLs.

    • Containers or VMs
    • BYOC
    • GPU
    • Pause/resume

    How it differs: Long-lived, stateful agent workspaces that need many SDK languages, GPUs, or Windows and macOS sandboxes. The strongest choice for stateful coding-agent workspaces and breadth of sandbox types; note the shift away from open source.

Compute platforms with sandboxes

General serverless or app platforms that also offer sandboxes, often with GPUs.

  • Control Plane Sandboxes

    Persistent, suspendable development sandboxes for coding agents inside a Control Plane "virtual cloud", with a browser IDE, SSH/VS Code/Cursor access and identity-based access to private services.

    • Container (runtime not named)
    • Self-hostable
    • BYOC
    • Pause/resume

    How it differs: Enterprises on Control Plane that want long-lived agent dev environments with identity-based access to their private infrastructure. A persistent dev-environment style sandbox for enterprises standardised on Control Plane, not a general-purpose SDK sandbox.

Cloud development environments

Cloud and in-browser development environments that coding agents increasingly run in.

  • GitHub Codespaces

    GitHub's cloud development environments: a Dev Container running on a freshly built, dedicated VM per codespace, created from the web, `gh` CLI or REST API, billed per core-hour with a free monthly quota.

    • Dedicated VM per codespace
    • Pause/resume

    How it differs: Developer-driven workspaces tied to GitHub repositories, where an agent assists a human inside a Dev Container. A solid VM-isolated workspace for humans and their assistants on GitHub, but its lifecycle and API are not designed for autonomous agent fleets.

  • Ona (formerly Gitpod)

    Enterprise cloud development environments provisioned as isolated VMs (EC2 or Compute Engine) in your own VPC from a Dev Container config, with SDKs, a CLI and Codex-based background agents; hosted Ona Cloud was retired on 31 October 2026.

    • Dedicated cloud VM
    • BYOC
    • GPU
    • Pause/resume

    How it differs: Enterprises that want VM-isolated, Dev Container-based environments for developers and background agents inside their own AWS or GCP VPC. A mature, VPC-native VM environment platform for enterprises, now enterprise-only and tied to OpenAI's Codex after the Ona Cloud shutdown.

Open-source runtimes to self-host

Open-source sandbox runtimes you run on your own servers or Kubernetes.

  • OpenHands Runtime

    The sandbox layer of the OpenHands agent SDK: an agent server that runs in a Docker container, in-process locally, or on the hosted OpenHands Runtime API.

    • Docker container
    • Open source
    • Self-hostable

    How it differs: Running OpenHands agents in disposable Docker sandboxes, locally or in CI, with the same server reachable through a hosted runtime for large evaluations. The right sandbox layer if you are already building on the OpenHands SDK; elsewhere a general container or microVM sandbox is simpler.
