## 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

## Mesa

Mesa solves a problem that shows up as soon as agents do real work: their compute is ephemeral, but the files they read and write should not be. Mesa provides a versioned virtual filesystem, MesaFS, that agents can mount like a normal directory, read and write with standard Unix tooling, and fork instantly. Repositories are version-controlled with branching, history and diffs, so every change an agent makes is traceable and reversible.

The design targets parallel agent workloads. Instead of locking files or letting agents clobber each other, you fork a workspace in milliseconds, run dozens of agents on isolated branches, and merge whichever result wins. Because MesaFS materializes files on demand, an agent can start working without cloning an entire repository, which keeps time-to-first-token low. Sub-50ms p95 random reads on large files and unlimited concurrent writers are the headline performance claims.

Beyond speed, Mesa adds the governance enterprises ask for: pause an agent for human review and resume from the exact same workspace state, snapshot the filesystem at any step and roll back in a single API call, version skills, memories and learned context as files the whole fleet can read and write, and enforce fine-grained access with short-lived tokens. Mesa can be deployed in your own AWS, GCP or Azure tenancy with the vendor operating only the control plane.

**Pricing & Plans:** Usage-based with three tiers. Free: $0/month including 50 GB storage, 1,000 repositories, 200 GB/month egress and unlimited virtual filesystem reads. Scale: pay-as-you-go at about $0.20/GB/month for storage and $0.11/GB egress for Git and REST API traffic, with the free allowance included. Enterprise: custom pricing with volume and committed-use discounts, self-hosted bring-your-own-cloud deployments, SOC 2 Type II and dedicated support. Reads through MesaFS are not metered.

- **Versioned virtual filesystem (MesaFS):** A 100% POSIX-compatible mount so agents and sandboxes use familiar Unix tools, with persistence, sync and version history handled transparently underneath.
- **Instant branches and parallel agent swarms:** Fork a workspace in milliseconds to run dozens of agents on isolated branches, then pick the best result without file locking.
- **Checkpoints and rollbacks:** Snapshot the entire filesystem at every step and restore any past state with a single API call when an agent goes off track.
- **Human-in-the-loop governance:** Pause any agent for review, build approval queues and policy gates, then resume from the exact same workspace state.
- **Enterprise-ready deployment:** Bring-your-own-cloud on AWS, GCP or Azure, SOC 2 Type II, AES-256 at rest, TLS 1.3 in transit, full access logging and fine-grained per-branch ACLs.

**Strengths:** Combines Git-style versioning with a fast, mountable filesystem; Instant forks make parallel agent swarms practical without locking; Strong enterprise story: BYOC, SOC 2 Type II, short-lived scoped tokens; Generous free tier with unlimited MesaFS reads

**Limitations:** Aimed at developers, so it requires engineering effort to adopt; Egress from Git and the REST API is metered even on paid tiers; Some capabilities are still framed as early access, so availability may vary
