Agentic Index
boxd vs Together Code Sandbox (2026)
Both vendors last verified
Both run agent code in isolated machines, and they suit different buyers. boxd sells persistent KVM machines that keep memory and processes, fork with memory in under 200ms and wake on the next request, with coding agents preinstalled, 128 integrations whose credentials stay outside the machine and a live desktop browser. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Together Code Sandbox, Together AI's successor to the CodeSandbox SDK, builds snapshots from Docker images on Together's servers and starts sandboxes from them to run commands, read files and serve ports, sized from a tenth of a vCPU up to 16, on the same account as Together's model inference. Together prices compute at $0.0446 per vCPU hour, with access to the current SDK requested through sales, and Together AI reports a SOC 2 Type 2 examination. Choose boxd when agents need a long lived machine they come back to, and Together Code Sandbox when sandboxes for generated code or rollouts should sit beside the models you already run on Together.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. boxd and Together Code Sandbox are each graded against the same 14 capability Agentic Index taxonomy, from the vendor's own public materials under the Agentic Index verification standard, alongside 1,165 researched vendors. No vendor pays for placement and no vendor has reviewed this page. How this evidence is graded
Choose boxd if
- Machines should keep memory and running processes between sessions and wake on the next request.
- Forks should copy a running machine with its memory, so rollouts start from identical warm state.
- You want to sign up and start today without a sales conversation.
- Agents should use integrations and a browser that come with the machine.
- You want to self host free up to 16 vCPUs.
Choose Together Code Sandbox if
- Your models already run on Together AI, and sandboxes should share the account and the bill.
- Environments should be defined as Dockerfiles and built remotely into reusable snapshots with aliases.
- Sandboxes should be sized finely, from a tenth of a vCPU up to 16, with 1 to 8 GB of memory per vCPU.
- Your security review relies on Together AI's SOC 2 Type 2 examination and HIPAA business associate agreements.
- You run Harbor benchmark jobs and want Together's guides for running them in sandboxes.

Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
boxdIntegrations & Tool Calling Agents on a machine act in outside systems through 128 integrations, including GitHub, Linear, Slack, Notion, Jira, Salesforce, HubSpot, Stripe and Zendesk, each with typed tools such as creating an issue or sending a message. A person connects an account once through the provider's consent screen, personally or as a shared connection for the whole organization, and the platform then makes each call on the machine's behalf, so the credential never enters the machine. The in machine run CLI and the @boxd/run SDK call these tools, and scripts reach any other API, database or cloud account with ordinary libraries.

Together Code SandboxIntegrations & Tool Calling No connectors, tool catalog, secrets store or credential brokering for outside systems comes with the sandboxes. Commands run with environment variables the caller passes on each execution, and an agent's code inside the sandbox reaches other systems on its own.

||
|
Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |
||
|
boxdWorkflow Orchestration Background jobs give automations a managed lifecycle. A script that registers a schedule or trigger runs as a job that survives reboots, waits for a missing connection instead of failing, and restarts with exponential backoff for up to five attempts before it is marked failed. boxd's fan out pattern has a coordinator create one machine per worker, run a coding agent headless in each and let a lead agent merge the reports, and a fork brings a machine's jobs along paused so nothing runs twice. The sequencing, branching and hand offs in that pattern are code the customer writes against the SDK, and boxd has no workflow graph, step model or multi agent runtime of its own.

||
|
Together Code SandboxWorkflow Orchestration There is no workflow logic in the product. The SDKs start sandboxes, run commands, retry failed API calls with backoff and list sandboxes by status and tag, but sequencing, branching and routing an agent's steps stay in the customer's own code.

|
Triggers & Channel Coverage How agents wake up and where they work: schedules, webhooks, message events, CRM events, inbox events, chat, email, voice, and collaboration tools. |
||
|
boxdTriggers & Channel Coverage Work reaches a machine on schedules, events and inbound requests. An automation registers durations or cron expressions with every() and subscribes to integration events with .on(), such as a new Linear issue or a pull request through the boxd GitHub App, and 36 integrations emit triggers. The platform holds the next due time and wakes a hibernated machine shortly before it, holds events that arrive while a machine wakes for up to 15 minutes, and fires a missed cron slot once on wake. A hibernated machine also wakes on the next HTTPS request, so an agent served from it answers webhooks at its own address. Sourcedocs.boxd.sh/guides/automations/scriptsread 2026-11-05 |
||
|
Together Code SandboxTriggers & Channel Coverage Sandboxes start only when the customer's code or the CLI creates them. There is no schedule, webhook or wake on inbound traffic, and a TTL only ends a sandbox. Sourcedocs.together.ai/docs/together-code-sandboxread 2026-11-05 |

| Knowledge & context | ||
|
Knowledge Grounding & RAG Ability to ground agent behavior in company data through document ingestion, retrieval, external knowledge APIs, semantic search, or RAG layers. |
||
|
boxdKnowledge Grounding & RAG No retrieval index, vector store or knowledge base over the customer's content comes with the platform. Files on a machine's disk, standalone disks that outlive a machine and data sets saved into a snapshot are storage the agent's code reads, not an index a query returns. Tools such as Notion, Confluence or Google Drive are searched through their own integrations, and any grounding layer is something the customer installs on the machine.

Together Code SandboxKnowledge Grounding & RAG No retrieval index or knowledge base comes with the sandboxes. Files an agent needs are built into the snapshot or written in at run time, and any retrieval runs in the customer's own code. Sourcedocs.together.ai/docs/together-code-sandboxread 2026-11-05 |
||
|
Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
boxdMemory & State Persistence Machines keep their working state between sessions. A machine on standby resumes in under a millisecond and a hibernated one wakes with its memory and processes intact, and coding agent sessions live on the persistent disk, so a job delegated in the morning can be resumed interactively later. Forks, checkpoints and snapshots copy or rewind that state. Automations also get object(name), a named JSON store written on every assignment and restored on the next run, meant for cursors, dedup sets and counters. All of it is machine and script state the developer manages, with no memory layer of stated scope and lifetime that a buyer can review, edit or delete as memory. Sourcedocs.boxd.sh/guides/automations/scriptsread 2026-11-05 |
||
|
Together Code SandboxMemory & State Persistence Work carries forward through snapshots. A sandbox can be terminated with a snapshot of its filesystem that takes an alias and starts the next sandbox, and many sandboxes can start from one snapshot. Together also promotes hibernation that keeps disk and memory and forks of hibernated sandboxes, which belong to the CodeSandbox SDK it now treats as deprecated. This is machine state the developer manages, with no memory layer of stated scope. Sourcedocs.together.ai/docs/together-code-sandboxread 2026-11-05 |

Human Oversight & Guardrails Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls. |
||
|
boxdHuman Oversight & Guardrails A person can step into an agent's work while it runs. Every machine has a live desktop in the browser where its owner watches the agent's browser, takes over the keyboard to enter a password, solve a captcha or fix a form, and hands control back without stopping the agent. The preinstalled coding agents are told to share that desktop link whenever they need someone, so a login or approval happens in the browser the agent already opened. There is no approval gate, pause primitive or policy that holds an agent's action until a person reviews it. Sourcedocs.boxd.sh/guides/desktopread 2026-11-05 |

|
Together Code SandboxHuman Oversight & Guardrails Work in a sandbox has no approval step, consent checkpoint or escalation to a person.

Security, Identity & Governance RBAC, SSO, auditability, encryption, least-privilege tool access, compliance posture, and data handling policy. |
||
|
boxdSecurity, Identity & Governance Organizations have three roles. Members use shared machines and create org billed ones, admins also invite and remove members, change roles, set defaults, create teams and revoke org API keys, and the single owner can demote admins. Admin invites need an interactive login, so an API key or a token minted inside a machine cannot send one. People sign in with GitHub or Google, with SAML single sign on offered to enterprise customers on request. A DPA is available, and SOC 2 Type II and ISO 27001 are both in progress, not held. Each machine is a KVM microVM with its own kernel, and egress allowlists and host bound secrets are enforced on the host, outside the machine. Sourcedocs.boxd.sh/guides/organizationsread 2026-11-05 |

Together Code SandboxSecurity, Identity & Governance Together AI has completed a SOC 2 Type 2 examination, supports HIPAA and signs business associate agreements, without naming the products the report covers. Organizations have admin and developer roles, projects have admin and editor roles with open, closed or private visibility, external collaborators can join single projects, and SAML or OIDC single sign on with Okta, Microsoft Entra or Google Workspace comes with Scale and Enterprise accounts. Sandboxes run under the account's Together API key, with no sandbox specific permissions among the roles. Sourcedocs.together.ai/docs/roles-permissions.mdread 2026-11-05 |

Observability & Auditability Traces, logs, execution histories, metrics, audit events, and debugging detail for production agent behavior. |
||
|
boxdObservability & Auditability Automations are visible and the agent's own steps are not. The console's Automations page lists every background job with its triggers in plain English, the integrations it uses, its state, last run and last error, plus a generated write up and flow diagram for each script, and run logs prints or follows a job's log from inside the machine. Regional uptime and incidents appear on a public status page. A coding agent's prompts, tool calls and outputs are not traced by the platform, and no audit trail of member actions is offered.

Deployment & Data Residency Deployment modes and options, including SaaS, dedicated cloud, VPC, on-prem, hybrid, local runtime, and self-hosting. |
||
|
boxdDeployment & Data Residency Each machine runs in Frankfurt or New York, picked per machine from the CLI, console or SDK or set as an organization default, and its disk, memory, snapshots, checkpoints and backups stay in that region on Latitude.sh bare metal. Scale customers can have boxd operate the cluster inside their own cloud account, and the same release self hosts on AWS, Google Cloud or any KVM host, free up to 16 worker vCPUs and licensed above that, with air gapped installs supported. boxd gives conflicting accounts of its US region, with New York live in some places and coming soon with a waitlist in others.

Together Code SandboxDeployment & Data Residency The CodeSandbox SDK runs in data centers in the US, Asia Pacific and Europe, but the current SDK has no region parameter or other way to choose where a sandbox runs.

Prebuilt Agents, Templates & Packs Ready-made workflows, packaged employees, templates, blueprints, industry solutions, and role-specific agents that reduce time-to-value. |
||
|
boxdPrebuilt Agents, Templates & Packs Machines arrive with Claude Code, Codex and OpenCode installed and configured through an instructions file that teaches each agent the platform, plus three preinstalled skills covering the in machine CLI, automations and the desktop, and a CLI skill for the laptop. Guides walk through development workspaces, preview environments, CI runners, personal assistants, sandboxes, agentic SaaS, RL environments and agent swarms, and connectors exist for open source tools such as TanStack AI, Pydantic AI, Harbor and Scale AI AgentEnv. These are configured third party agents and recipes a developer builds from, not prebuilt agents of boxd's own. Sourcedocs.boxd.sh/use-cases/coding-agentsread 2026-11-05 |

Together Code SandboxPrebuilt Agents, Templates & Packs Starting points are snapshots and guides. Snapshots build from any public Docker image or Dockerfile and take reusable aliases, the legacy SDK ships a Universal template, and Together's guides cover running Harbor benchmark jobs and a Tinker with Harbor recipe in sandboxes.

Model Flexibility & Routing Ability to work across multiple foundation models, route tasks to different models, or let buyers bring their own providers and keys. |
||
|
boxdModel Flexibility & Routing The customer decides which agents and models run. Claude Code and Codex use the customer's own subscription, signed in once and served to every private machine in the organization, or an API key stored as a secret, OpenCode signs in on each machine, and any other agent or model that runs on Linux can be installed. boxd adds no model of its own and does not route between providers, and it does not use customer data to train or improve any model.

Together Code SandboxModel Flexibility & Routing The customer chooses the models its agents use.

APIs, SDKs & MCP Extensibility Composability layer: stable APIs, SDKs, MCP tool consumption/serving, custom tools, and integration into internal systems. |
||
|
boxdAPIs, SDKs & MCP Extensibility Outside code drives the platform through TypeScript and Python SDKs, a gRPC API whose full api.proto service definition is public for generating stubs in any language, and a CLI that returns JSON from its commands. Each region has its own API endpoint, and organization API keys keep working after the person who created them leaves. The SDKs cover machines, forks, snapshots, checkpoints, disks, egress, secrets, domains, organizations and teams, and a filesystem API reads and writes files inside a machine from code.

boxdTesting, Debugging & Optimization There are no test cases, scoring or quality gates for an agent's behavior. The platform is where evaluations run, not how they are scored. Forks give every reinforcement learning rollout or benchmark trial a byte identical starting state, Moyai ran 279,577 Harbor benchmark machines on it, and a reproducibility check compares two forks run with the same seed, but rewards, datasets and scoring belong to the customer's own framework.

boxdBrowser & Computer Use Agents drive a real browser on the machine's own desktop. Every machine ships a browser automation CLI built for agents, backed by Chromium with anti bot fingerprinting and a persistent profile so logins stick, and scripts get the same browser through Playwright. A machine can also drive a Chrome window on the user's laptop over the DevTools protocol, for sites that only accept the user's own network, and the preinstalled agents get a browser tool for it automatically. Any GUI app installed on the machine opens on the same desktop. Sourcedocs.boxd.sh/guides/launch-a-browserread 2026-11-05 |
