## 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

## Replit

Replit began as one of the most popular browser-based coding environments and has evolved into an AI-first app and website builder. You describe what you want to build, and Replit's agent plans the work, writes production-ready code across the stack, iterates on feedback, and can publish the running app for you. Because everything happens in the cloud, there is no toolchain to install and no local environment to maintain.

The platform pairs the agent with the infrastructure a real product needs: authentication, a managed database, hosting, monitoring and more than a hundred integrations such as OpenAI, Stripe and Google Workspace. Recent releases added intelligent model routing that cuts the average cost of complex builds, an infinite canvas for visual design iteration and multi-user collaboration features aimed at teams.

Replit suits a very wide audience. Founders use it to go from idea to landing page or prototype in an afternoon, product managers build interactive demos instead of static specs, designers move straight from concept to functioning UI, and engineering teams use it to spin up internal tools quickly. A generous free mode lets people create without token costs, while paid plans unlock more powerful models, more storage and commercial usage.

**Pricing & Plans:** There is a free mode with limited chat hours and projects. Replit Core is about $20/month (about $18/month billed annually), and Replit Pro is roughly $90–100/month billed annually for commercial work. Enterprise plans add SSO/SAML, SOC 2 controls and admin features.

- **Agentic app generation:** Describe the product you want and the agent plans, codes, tests and iterates on a working full-stack application.
- **Built-in full-stack infrastructure:** Authentication, databases, hosting and monitoring work out of the box, so apps scale without separate DevOps work.
- **Free mode for experimenting:** A no-cost mode lets you brainstorm and build without spending tokens before upgrading to stronger models.
- **100+ integrations:** Connect services such as OpenAI, Stripe and Google Workspace in minutes rather than writing glue code.
- **Team and enterprise controls:** Multi-user collaboration, SSO/SAML, SOC 2 alignment and admin controls support professional and regulated use.

**Strengths:** No local setup; everything runs and deploys in the browser; Agent handles full-stack code, infrastructure and publishing; Free mode makes experimentation accessible; Strong collaboration, integrations and enterprise security controls

**Limitations:** Complex or highly custom architectures may still need manual engineering; Agentic build costs can rise quickly on heavier projects; Less control over low-level infrastructure than managing your own stack
