Agentic Index

boxd vs E2B (2026)

boxd last verified ·E2B last verified

Both give AI agents isolated Linux microVMs with their own kernel that can pause, resume and fork with memory intact, and they differ in how long a machine is meant to live and what comes with it. boxd sells persistent cloud computers. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.

Each KVM machine keeps its files, memory and processes between sessions, forks while running in under 200ms, hibernates after four idle hours and wakes on the next request, and ships with Claude Code, Codex and OpenCode installed, 128 integrations whose credentials stay outside the machine and a live desktop where an agent drives a browser while a person can step in. E2B sells Firecracker sandboxes that an agent's code creates through an SDK, with pause and resume, auto resume on incoming requests, secrets injected at the egress proxy, an MCP gateway to more than 200 tools and Desktop sandboxes for computer use. boxd bills in euros per second with no plan fee and runs in Frankfurt or New York or on the customer's own servers, while E2B pairs a free Hobby or $150 Pro plan with per second usage, holds SOC 2 Type II and runs on Google Cloud and AWS. Choose boxd when agents need a long lived machine with tools and integrations ready, and E2B when you want a widely used sandbox API with a completed SOC 2 report.

This comparison is published by Agentic Index, an independent agentic AI vendor research platform. boxd and E2B 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

  • Agents run for hours or days and should come back to the same machine, with files, memory and running processes kept between sessions.
  • Coding agents should start with Claude Code, Codex and OpenCode already installed and a CLI on the machine to create and fork more machines.
  • Agents need to act in GitHub, Linear, Slack, Salesforce or Stripe through 128 integrations whose credentials never enter the machine.
  • A person should be able to watch an agent drive its browser on a live desktop and take over the keyboard to finish a login or a captcha.
  • EU hosting by default matters, or you want to self host the same release free up to 16 vCPUs.

Choose E2B if

  • Your security review needs a completed SOC 2 Type II report now, with HIPAA BAAs on Enterprise.
  • Agents should reach more than 200 tools from the Docker MCP Catalog through a gateway inside the sandbox.
  • You want desktop sandboxes with screen, mouse and keyboard control through a dedicated Desktop SDK.
  • Sandboxes should run in your own AWS, Google Cloud or Azure account on Enterprise.
  • You want an open source sandbox used by more than 100,000 teams, with a free Hobby plan and a $100 credit to start.

Action & orchestration

Integrations & Tool Calling

Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools.

Workflow Orchestration

Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps.

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.

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.

Memory & State Persistence

Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer.

Control & trust

Human Oversight & Guardrails

Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls.

Security, Identity & Governance

RBAC, SSO, auditability, encryption, least-privilege tool access, compliance posture, and data handling policy.

Observability & Auditability

Traces, logs, execution histories, metrics, audit events, and debugging detail for production agent behavior.

Deployment & Data Residency

Deployment modes and options, including SaaS, dedicated cloud, VPC, on-prem, hybrid, local runtime, and self-hosting.

Solution readiness

Prebuilt Agents, Templates & Packs

Ready-made workflows, packaged employees, templates, blueprints, industry solutions, and role-specific agents that reduce time-to-value.

Platform extensibility

Model Flexibility & Routing

Ability to work across multiple foundation models, route tasks to different models, or let buyers bring their own providers and keys.

APIs, SDKs & MCP Extensibility

Composability layer: stable APIs, SDKs, MCP tool consumption/serving, custom tools, and integration into internal systems.

Testing, Debugging & Optimization

Testing, debugging, scoring, retries, fallbacks, quality gates, and optimization loops for improving agent workflows before and after deployment.

Specialist automation

Browser & Computer Use

E2B

  • · Security / enterprise

    Secrets, now generally available in E2B, keep credentials outside the sandbox: a team stores a credential from its backend, references it by name in a sandbox network rule, and E2B injects the value into the configured HTTPS request headers after the request leaves the sandbox.

    Source
  • · MCP / tool calling / API

    E2B deprecated E2B_ACCESS_TOKEN authentication in favor of E2B_API_KEY.

    Source
  • · Funding / partnership

    E2B joined the Stripe Projects developer preview so agents can discover, provision, and authenticate E2B sandboxes without manual API-key setup.

boxd gives conflicting accounts of its US region, live in some places and coming soon in others, and its SOC 2 Type II and ISO 27001 certifications are still in progress. boxd prices in euros.
