Overview
Cloudflare (NYSE: NET) is a publicly traded connectivity cloud company founded in 2009 and headquartered in San Francisco. In the AI Code Sandboxes & Agent Runtimes vertical, its primary offering is the Sandbox SDK—a developer tool that provisions secure, isolated Linux container environments accessible via a TypeScript API from Cloudflare Workers, with no infrastructure to manage. Built on Cloudflare's global Containers platform (330+ cities, 125+ countries), the Sandbox SDK supports command execution, file management, background processes, browser terminals, code interpretation, and persistent storage via R2. It integrates natively with Workers AI, Durable Objects, and Cloudflare AI Gateway, making it purpose-built for AI agents that need to run untrusted or LLM-generated code at scale. The SDK reached general availability during Cloudflare's Agents Week in April 2026. FY2025 revenue was $2.17B.
Cloudflare Sandbox SDK is a managed code execution environment platform that allows developers to spin up secure, isolated Linux containers from Cloudflare Workers via a TypeScript API. It is designed for building AI agents that execute untrusted or LLM-generated code, interactive development environments, data analysis notebooks, and CI/CD systems. Each sandbox provides a full Linux environment with shell access, file management, persistent storage, WebSocket-connected browser terminals, real-time filesystem watching, and native integration with Workers AI for AI-native workflows. The product runs on Cloudflare's global edge network and requires no infrastructure management.

Alternatives in AI Code Sandboxes & Agent Runtimes6
Cloudflare Sandbox SDK differentiates itself from standalone AI sandbox/agent runtime providers through deep integration with Cloudflare's global edge network (330+ cities, 125+ countries), zero-trust security by default, and a comprehensive developer platform ecosystem (Workers, AI Gateway, R2, Durable Objects).
- Unlike pure-play sandbox competitors such as E2B or Morph Labs, Cloudflare offers sandboxes as one layer of a full agentic infrastructure stack—covering inference, storage, identity, and networking alongside code execution.
- Pricing is consumption-based and tied to the existing Workers Paid plan, lowering the barrier for existing Cloudflare customers.
- Cloudflare was named a Leader in the 2026 Forrester Wave for Edge Development Platforms, reinforcing its positioning as infrastructure-native.
- The Sandbox SDK (GA announced April 2026) is positioned as the compute primitive for Cloudflare's self-described 'agentic cloud' strategy.
Reviews
Praised
- Global edge performance and low latency
- Generous free tier with broad feature access
- Unified security and performance on one platform
- Easy setup and intuitive dashboard
- Developer-friendly APIs and Workers extensibility
- Strong DDoS protection and WAF
- Comprehensive documentation and tutorials
Criticized
- High enterprise pricing
- Occasional outages affecting large portions of the internet
- Real-time logs require third-party tools
- Advanced configuration complexity and steep learning curve
- Documentation fragmented across many products
- Support quality varies by plan tier
Review data specific to the Cloudflare Sandbox SDK is not yet available given its recent GA status (April 2026). Across its broader developer platform, Cloudflare, Inc. is rated 4.5/5 on G2 from 697 verified reviews. Reviewers consistently praise the platform's ease of setup, strong free tier, global network performance, and unified security-plus-performance design. Common criticisms include high enterprise pricing, occasional high-impact outages, real-time log retrieval complexity requiring third-party tools, and steep configuration learning curves for advanced policies.
Pricing
The Sandbox SDK requires a Cloudflare Workers Paid plan ($5/month). Pricing is consumption-based on the underlying Containers platform: memory at $0.0000025/GiB-second (25 GiB-hours/month included), vCPU at $0.000020/vCPU-second (375 vCPU-minutes/month included), and disk at $0.00000007/GB-second (200 GB-hours/month included). Six instance types are available from 'lite' (1/16 vCPU, 256 MiB RAM, 2 GB disk) to 'standard-4' (4 vCPU, 12 GiB RAM, 20 GB disk). Network egress is $0.025/GB in North America and Europe (1 TB/month included). Additional Workers and Durable Objects usage charges apply per standard Cloudflare pricing.
Limitations
- The Sandbox SDK was in Beta through early 2026 and only reached GA in April 2026, meaning SLAs, feature stability, and documented limits may still evolve.
- The product is tightly coupled to the Cloudflare Workers ecosystem, limiting portability to other clouds.
- A Workers Paid plan ($5/month minimum) is required; the free tier has no sandbox access.
- HTTP transport mode is subject to Workers subrequest limits (1,000/request on paid).
- Some features—such as S3-compatible bucket mounting—require production deployment (not available in local development).
- No native GPU/CUDA support is documented for ML inference workloads within sandboxes; GPU inference is routed through Workers AI separately.
- Beta-era documentation is acknowledged to sometimes lag behind features.
