Provides a three-tier architecture that abstracts container orchestration across Docker and Kubernetes backends through a unified Lifecycle API. The OpenSandbox Server acts as a control plane that translates client requests into runtime-specific operations, managing sandbox creation, execution, pause/resume, and termination. Supports auto-renewal on ingress access and sandbox state persistence across multiple runtime implementations without requiring clients to understand underlying infrastructure.
Unique: Implements WorkloadProvider abstraction pattern that decouples sandbox lifecycle from runtime implementation, enabling seamless switching between Docker and Kubernetes via configuration without code changes. Includes auto-renewal mechanism that automatically extends sandbox lifetime on ingress access, reducing manual lifecycle management overhead.
vs alternatives: Unlike Docker SDK or kubectl which require runtime-specific code, OpenSandbox provides a single API surface that works across runtimes and includes built-in pause/resume with state preservation, critical for cost-optimized AI agent platforms.
A lightweight daemon running inside each sandbox container that handles command execution, file I/O, and multi-language code interpretation through an event-driven execution model. The execd component receives requests from the OpenSandbox Server, executes commands in isolated process contexts, manages file operations with permission controls, and streams execution results back. Supports Python, JavaScript, Java, C# and shell commands with language-specific interpreters pre-configured in the sandbox image.
Unique: Uses event-driven execution model with streaming results rather than batch processing, enabling real-time output capture for interactive REPL-like experiences. Implements context management and isolation at the process level, ensuring each code execution runs in a separate process context with independent resource limits.
vs alternatives: Compared to subprocess-based execution, execd provides better isolation and resource control through containerization; compared to cloud-based code execution services, it offers lower latency and full control over execution environment without vendor lock-in.
Implements hardened container runtime configurations that drop unnecessary Linux capabilities (CAP_SYS_ADMIN, CAP_NET_RAW, etc.) and enforce strict resource limits (CPU, memory, disk, processes). Supports multiple secure runtime options including standard Docker/Kubernetes runtimes with security policies, and integration with specialized secure runtimes like gVisor or Kata Containers for additional isolation. Resource limits are enforced at the cgroup level, preventing resource exhaustion attacks.
Unique: Implements defense-in-depth security through capability dropping, cgroup-based resource limits, and optional integration with specialized secure runtimes. Provides configuration options to balance security and performance based on threat model.
vs alternatives: Unlike standard Docker containers which retain many capabilities, OpenSandbox drops unnecessary capabilities by default. Compared to specialized runtimes alone, the layered approach (capability dropping + resource limits + optional gVisor) provides better protection against multiple attack vectors.
Provides a command-line interface for interacting with OpenSandbox, enabling developers to create sandboxes, execute code, manage files, and inspect sandbox state from the terminal. The CLI supports both local development (connecting to local OpenSandbox Server) and remote deployments (connecting to cloud-hosted servers). Includes commands for sandbox lifecycle management, code execution, file operations, and diagnostics.
Unique: Provides a unified CLI interface for all OpenSandbox operations, supporting both local development and remote deployments with consistent command syntax. Includes shell completion and interactive modes for improved developer experience.
vs alternatives: Unlike raw HTTP clients or SDKs, the CLI provides a user-friendly interface for common operations without requiring code. Compared to docker/kubectl CLIs, osb is sandbox-specific and abstracts away runtime complexity.
Provides a web-based dashboard for visualizing sandbox state, monitoring execution, and managing sandbox lifecycle through a graphical interface. The console displays sandbox metrics (CPU, memory, network), execution logs, file system contents, and provides interactive controls for creating/destroying sandboxes and executing code. Includes real-time updates via WebSocket connections, enabling live monitoring of sandbox activity.
Unique: Provides real-time visualization of sandbox metrics and execution state through WebSocket-based live updates, enabling operators to monitor multiple sandboxes simultaneously. Includes interactive code execution and file management directly in the web UI.
vs alternatives: Unlike CLI-only tools, the web console provides visual monitoring and is accessible to non-technical users. Compared to generic container dashboards (Kubernetes Dashboard, Portainer), the console is sandbox-specific and includes execution-focused features.
Implements comprehensive request validation at the OpenSandbox Server level, validating sandbox configuration, execution parameters, and network policies against defined schemas. Uses JSON Schema validation to ensure requests conform to expected formats, with detailed error messages for validation failures. Prevents invalid configurations from reaching the runtime layer, catching errors early and improving debugging experience.
Unique: Implements JSON Schema-based validation with detailed error reporting that identifies specific fields and validation rules that failed, enabling developers to quickly fix configuration issues. Validation happens at the API boundary, preventing invalid configurations from reaching the runtime.
vs alternatives: Unlike permissive APIs that accept any configuration and fail at runtime, OpenSandbox validates early with detailed error messages. Compared to client-side validation alone, server-side validation ensures consistency regardless of client implementation.
Implements a dedicated egress control sidecar that runs alongside each sandbox container, enforcing network policies through a DNS proxy layer and nftables-based network filtering. The sidecar intercepts DNS queries, applies policy-based filtering, and uses Linux netfilter rules to allow/deny network traffic based on configured policies. Supports granular control over outbound connections, preventing data exfiltration and limiting sandbox access to approved external services.
Unique: Combines DNS proxy layer with nftables filtering in a dedicated sidecar process, providing defense-in-depth where DNS-level blocking prevents resolution and netfilter rules block any direct IP-based access. This two-layer approach prevents DNS rebinding attacks and IP spoofing while maintaining low overhead.
vs alternatives: Unlike simple firewall rules or iptables, the DNS proxy + nftables combination provides both DNS-level and network-level enforcement with policy-based filtering, offering better protection against sophisticated exfiltration attempts than single-layer approaches.
Provides a SandboxPool abstraction that manages a pool of pre-warmed sandbox instances, reducing cold-start latency for rapid sequential executions. The pool maintains a configurable number of ready sandboxes and automatically scales based on demand, reusing containers across multiple execution requests. Integrates with Kubernetes BatchSandbox and Pool CRDs for declarative pool management, enabling teams to define pool configurations as Kubernetes resources.
Unique: Implements both programmatic SandboxPool API and Kubernetes CRD-based declarative management, allowing teams to define pools as YAML resources that are reconciled by Kubernetes operators. Includes automatic cleanup and state isolation between pool reuses, preventing cross-request contamination.
vs alternatives: Unlike container orchestration platforms that require manual scaling, SandboxPool provides application-level pooling with automatic reuse and cleanup, reducing cold-start latency by 80-90% compared to creating fresh containers per request while maintaining isolation guarantees.

Pipelines are reusable, testable, and can be deployed as APIs or batch jobs.
Unique: Provides a flexible pipeline composition API supporting both declarative and programmatic definitions, with automatic dependency resolution and execution optimization. Enables complex workflows with branching and conditional logic without custom orchestration code.
vs alternatives: More flexible pipeline composition than fixed RAG architectures; better workflow support than manual component chaining.
Generates embeddings for documents/nodes using pluggable embedding providers (OpenAI, Hugging Face, local models) and stores them in a unified vector store interface that abstracts over multiple backends (Pinecone, Weaviate, Milvus, FAISS, Chroma, etc.). The abstraction layer enables switching vector stores without changing application code, and handles batching, retry logic, and metadata indexing.
Unique: Provides a unified VectorStore interface that abstracts 10+ vector database backends, enabling zero-code switching between providers. Handles embedding batching, retry logic, and metadata propagation automatically. Supports both cloud and local embedding models through a pluggable EmbedModel interface.
vs alternatives: Broader vector store coverage and more seamless provider switching than LangChain's vectorstore integrations; better abstraction consistency across backends than using raw vector store SDKs directly.
Retrieves semantically similar documents from vector stores using embedding-based similarity search, with optional re-ranking, filtering, and fusion strategies (hybrid search combining dense and sparse retrieval). Supports multiple retrieval modes (similarity, MMR, fusion) and enables custom retrieval logic through a pluggable Retriever interface that can combine multiple strategies.
Unique: Implements a pluggable Retriever abstraction supporting multiple retrieval strategies (similarity, MMR, fusion, custom) that can be composed and chained. Built-in support for re-ranking via LLM or cross-encoder, and hybrid search combining dense and sparse retrieval without custom integration code.
