Daytona provides isolated sandbox infrastructure specifically built for AI agents and coding tools that need to execute untrusted, AI-generated code. Each sandbox spins up in under 90ms and runs in a fully isolated environment, so code execution never touches your host infrastructure. It's built for teams running AI agents at scale, where thousands of sandboxes may be created and torn down in parallel.

Compared to tools like E2B or Together Sandbox, Daytona's key differentiator is its stateful design. Sandboxes run indefinitely and support environment snapshots, so long-running agent workflows can be paused, saved, and resumed without losing state. Shared volumes let multiple sandboxes access the same data without breaking isolation.

The programmatic API covers everything an agent needs at runtime:

• Process execution with real-time output streaming and configurable timeouts
• File system operations with full CRUD and granular permission controls
• Git integration with native operations and secure credential handling
• Built-in LSP support for multi-language code completion and real-time analysis
• Computer use sandboxes providing isolated Linux, macOS, and Windows desktops with full programmatic control
• Docker support including Docker-in-Docker, Dockerfile, and Docker Compose, so existing images work without modification

Sandboxes can be deployed in multiple regions (US, EU, Asia) to keep latency low relative to where your agents run. For debugging or oversight, SSH access, a browser-based VS Code instance, and a web terminal are available without additional setup.

Security is handled through customer-managed compute. Sandboxes run on isolated, customer-controlled infrastructure in your cloud or on-premises. Daytona operates the control plane only, with no shared compute across tenants. The platform meets HIPAA, SOC 2, and GDPR standards, and the codebase is open source for full auditability.

Pricing is pay-as-you-go, billed per second for compute, memory, and storage, with GPU options including Nvidia H100 for workloads like reinforcement learning or data analysis.

E2B delivers secure cloud environments specifically designed for enterprise AI agents, providing isolated sandboxes where agents can safely execute code, access real-world tools, and perform complex tasks without compromising security.

Key capabilities include:

• Secure code execution in isolated Firecracker-powered microVMs with full system access
• Multi-language support for Python, JavaScript, Ruby, C++, and any Linux-compatible framework
• Ultra-fast startup with sub-200ms initialization times and no cold starts
• Extended sessions up to 24 hours for long-running agent workflows
• Enterprise security with complete isolation and secure file handling

Perfect for advanced AI use cases:

• Deep research agents conducting analysis on large datasets
• Data visualization with secure chart generation and analysis
• Computer use agents with virtual desktop environments
• Reinforcement learning with thousands of concurrent sandbox instances
• Code generation and testing with real-time error inspection

Trusted by leading organizations including 88% of Fortune 100 companies, E2B integrates seamlessly with OpenAI, Anthropic, Mistral, LangChain, and custom models. The platform offers flexible deployment options including BYOC, on-premises, and self-hosted solutions to meet enterprise compliance requirements.

Beam is a GPU compute platform built specifically for AI workloads. It handles serverless inference, durable task queues, and isolated sandboxes, all defined in Python without Dockerfiles or YAML config. You can run on Beam's cloud or connect your own AWS, GCP, or bare metal accounts and let Beam orchestrate across all of them.

The core differentiator is boot time. Beam uses memory snapshots to restore GPU containers in under a second, up to 35× faster than a traditional cold start. That matters when you're running inference at scale or building agent pipelines where latency compounds quickly.

Key capabilities:

• GPU inference endpoints – deploy models on H100s, A10Gs, or 4090s with autoscaling baked in. Scale to zero when idle, burst to hundreds of containers when traffic spikes.
• Task queues – durable, queue-depth-based autoscaling with automated retries, scheduled jobs, and event callbacks. Good for batch workloads like transcription or document processing.
• Sandboxes – stateful, long-running environments for AI agents. Attach persistent storage, run Docker-in-Docker, snapshot the filesystem, and branch into thousands of parallel isolated runs.
• Multi-cloud routing – workloads route across clouds and 30+ regions in real time, keeping execution close to your users.
• CI/CD integration – deploy directly from GitHub Actions without changing your workflow.

Compared to tools like Modal or dstack, Beam leans hard on the sandbox and snapshotting story, which makes it a natural fit for agent frameworks that need stateful, parallelizable execution environments.

Pricing starts at $0.69/hr for a 4090, with $30 in free credits refreshed monthly. SOC 2 Type II certified.
