## Agent Sandbox

Agent Sandbox provides the missing "computer" for AI agents. Instead of letting an agent execute code on your own machines, you send the code to the Agent Sandbox API, which runs it in a sandboxed workspace with Python 3.11, memory and timeout limits, and no access to your infrastructure. This is the pattern behind code interpreters, data-analysis agents, and any tool-using model that needs to actually run something rather than just describe it.

The service covers the full round trip. Agents can install the libraries they need, which are provisioned reproducibly per run; upload input data such as CSV files; and download whatever the code produces, from charts to transformed datasets. It ships as a single tool that plugs into any agent framework, client-side or server-side, via the agentsandbox-sdk Python package.

Pricing is purely consumption-based with no subscription: new users who sign in with Google receive $10 in free credits (roughly 11 hours of compute), compute costs $0.00025 per second billed by the second, and output file storage costs $0.0005 per MB. Credits are bought in amounts from $5 to $1,000, and a dashboard tracks balance, usage history, and spending. The platform documents compatibility with Claude Code, Codex, Cursor, Windsurf, and Cline.

**Pricing & Plans:** Pay-as-you-go with no subscription. New users get $10 in free credits on Google sign-in (~11 hours of compute); compute is $0.00025/second (billed per second) and output storage is $0.0005/MB. Credits can be purchased in $5–$1,000 increments.

- **Sandboxed Python and Bash execution:** Run real Python 3.11 and shell commands inside an isolated workspace with memory and timeout limits, keeping untrusted code off your own machines.
- **Automatic dependency installation:** List the libraries or system tools your agent needs and they are installed automatically and reproducibly for that run.
- **File upload and artifact retrieval:** Send input data for processing and download everything the agent creates, including charts, logs, reports, and transformed datasets.
- **Drop-in agent integration:** Use it as a single tool inside any agent framework with the agentsandbox-sdk, working client-side or server-side with minimal setup.
- **Usage dashboard and per-second billing:** Track balance, usage history, and spending patterns, with compute charged per second and no commitments.

**Strengths:** Genuinely isolated execution with memory and timeout limits; Usage-based pricing with per-second billing and no subscription commitment; Handles dependencies, files, and artifacts in one API; Works with popular agent tools including Claude Code, Codex, Cursor, Windsurf, and Cline

**Limitations:** Requires developer effort to wire the SDK into an existing agent stack; Costs scale with compute seconds, so long-running code can add up; Sandbox limits (memory, timeout) may not suit heavy workloads

## Arcjet

Arcjet started life as a developer-friendly security layer for web applications and has expanded into runtime security for AI agents. Instead of only checking identity at the door, it evaluates every step an agent takes: which tool is being called, with which typed arguments, by which actor, and in the context of the steps that came before. That lets teams stop unauthorized refunds, unexpected data access, runaway token spend and sequence drift that no single step would have flagged on its own.

The platform combines classic application protections - WAF, bot detection, rate limiting, signup form protection and email validation - with agent-specific controls such as prompt injection detection, tool and MCP authorization, sensitive information detection and data loss prevention. Detection for sensitive data can run locally in your environment so regulated payloads never leave your infrastructure, while decisions and policy versions stream out to SIEM tools like Splunk, Datadog, Panther and Cribl for evidence.

Arcjet ships SDKs for JavaScript and Python ecosystems (Next.js, Astro, Express, Fastify, NestJS, Nuxt, SvelteKit, Hono, Flask, FastAPI, Bun, Deno and more) plus integrations for agent frameworks including LangChain, LangGraph, CrewAI, Google ADK, Mastra, OpenAI Agents, Vercel AI SDK and the Claude Agent SDK. It also offers an MCP server, a CLI and skills for coding agents such as Claude Code, Codex and Cursor. A free trial is available, with paid plans and custom/enterprise pricing on request.

**Pricing & Plans:** Free trial available, then paid plans with custom pricing for larger deployments. Enterprise and volume pricing is quoted on request. Check the official pricing page for current tiers and usage limits.

- **Agent action policy enforcement:** Wrap agent tool calls and get a typed decision - allow, block, redact or hold for review - before the tool actually executes, based on actor, role, route and typed inputs.
- **Prompt injection detection:** Screen user input, fetched web pages, API responses and tool output for hostile instructions before anything reaches the model context.
- **Sensitive information and DLP:** Detect and strip names, addresses, national IDs, bank and card numbers before they reach model context, logs or third-party tools, with optional in-process local detection.
- **Web app protections:** Bot protection, WAF rules, rate limiting, signup form protection and email validation to keep public endpoints and signup flows clean.
- **Audit and observability:** Every decision, policy version and actor is retained as evidence and streamed to Splunk, Datadog, Panther, Cribl or your own analytics warehouse, with OpenTelemetry agent traces.

**Strengths:** Evaluates the whole agent run, not just a single request, which catches sequence drift and multi-step abuse; Detection can run in-process so sensitive data does not have to leave your environment; Broad SDK and agent-framework coverage, including an MCP server, CLI and coding-agent skills; Decisions and policy versions stream to common SIEM and observability stacks for compliance evidence

**Limitations:** Requires code changes inside your application rather than a purely network-level gateway deployment; The breadth of controls and frameworks means a real learning curve for smaller teams; Advanced enterprise governance and custom retention options are quote-based rather than self-serve
