Agentic Index
Blaxel vs E2B (2026)
Blaxel last verified ·E2B last verified
Both run agent sandboxes as microVMs that pause and resume with memory intact and wake when a request arrives, and they bundle different things around them. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
Blaxel, owned by Baseten since September 2026 and still sold under its own name, suspends a sandbox after about five seconds idle and resumes it in about 25ms, and adds hosted agents and MCP servers, batch jobs, a shared Agent Drive, a model gateway across eight providers and an egress proxy that injects secrets, in Oregon, North Virginia, London or Frankfurt. E2B runs Firecracker sandboxes with pause, resume, snapshots and forks, auto resume on incoming requests, secrets injected at its egress proxy, an MCP gateway to more than 200 tools and Desktop sandboxes for computer use, and it can run inside a customer's AWS, Google Cloud or Azure account. Both hold SOC 2, and Blaxel adds ISO 27001, SAML and SCIM. Choose Blaxel when you want sandboxes, agent hosting and model routing from one vendor, and E2B when you want a widely used sandbox with desktops for computer use and a path into your own cloud.
This comparison is published by Agentic Index, an independent agentic AI vendor research platform. Blaxel 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 Blaxel if
- Sandboxes should suspend within seconds of going idle and resume in about 25ms, with no compute charge in between.
- Agents, MCP servers and batch jobs should be hosted next to the sandboxes.
- Model calls should route through one gateway to eight providers with central credentials.
- Your security review needs ISO 27001 as well as SOC 2, with SAML and SCIM for the workspace.
- Location policies should keep sandboxes inside allowed regions, in the US, London or Frankfurt.
Choose E2B if
- Agents need a desktop with screen, mouse and keyboard control for computer use.
- More than 200 tools from the Docker MCP Catalog should be available through a gateway inside the sandbox.
- You want the open source runtime packaged for a self hosted install through E2B Embed.
- A free Hobby plan with a $100 credit should cover early experiments.
- Signed lifecycle events should arrive at your webhook.

|
Integrations & Tool Calling Ability to connect agents to real systems through native integrations, OAuth-authenticated actions, custom tools, APIs, webhooks, or MCP-compatible tools. |
||
|
BlaxelIntegrations & Tool Calling Agents reach outside systems through hosted MCP servers. The MCP Hub offers prebuilt servers such as Gmail and Google Maps, customers deploy their own MCP servers as autoscaling endpoints on the same private network as their agents, an OAuth flow lets end users authorize integration connections, and code mode turns any OpenAPI specification into an MCP server whose tools the agent calls by running TypeScript in a sandbox. Outbound calls from a sandbox can also carry secrets injected by the managed egress proxy, so the agent's code never holds the credential. Sourcedocs.blaxel.ai/functions/overviewread 2026-11-05 |
||
|
E2BIntegrations & Tool Calling An agent in a sandbox reaches other systems through a built in MCP gateway that runs inside the sandbox and exposes more than 200 tools from the Docker MCP Catalog (Airtable, GitHub, Browserbase, Exa and others) or custom MCP servers through one interface. Credentials are passed as secrets that resolve at egress instead of living in the sandbox. Sourcedocs.e2b.dev/mcp-gatewayread 2026-11-03 |
||
|
Workflow Orchestration Ability to sequence, branch, retry, route, and combine deterministic workflow nodes with autonomous agent steps. |
||
|
BlaxelWorkflow Orchestration Batch jobs fan work out across many isolated sandboxes, running tasks in parallel with configurable concurrency, timeouts and retries, and executions can be started, monitored, retried and cancelled from the SDKs. Agents built with LangChain, CrewAI or other frameworks deploy as hosted endpoints, and n8n can orchestrate them. How an agent's own steps are sequenced and handed off stays in the customer's framework, and Blaxel's own session runtime for long running agents is announced but not yet available. Sourcedocs.blaxel.ai/jobs/overviewread 2026-11-05 |
||
|
E2BWorkflow Orchestration There is no workflow logic in E2B itself. The customer brings its own orchestration framework, and E2B provides the machine an agent's steps run on (commands, background processes, code contexts), not a runtime that sequences, branches, retries or routes those steps. Forking a sandbox copies its state, which is compute, not workflow logic. Sourcee2b.dev/llms.txtread 2026-11-03 |
||
|
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. |
||
|
BlaxelTriggers & Channel Coverage Work starts on schedules, API calls and inbound requests. Sandbox schedules run a command on a cron expression, at a future datetime or after a delay, with an execution history for each run, and batch jobs run on cron schedules or on demand. Hosted agents and MCP servers answer at global endpoints, and a sandbox on standby resumes in about 25ms when a connection arrives. Sourcedocs.blaxel.ai/sandboxes/schedulesread 2026-11-05 |
||
|
E2BTriggers & Channel Coverage A sandbox can start without the customer's code calling it. With auto resume set, a paused sandbox resumes when activity arrives, so an agent served from a sandbox starts on an inbound request, and E2B's guides deploy agent gateways this way, for example OpenClaw answering Telegram. Sandbox lifecycle events are also pushed to the customer's webhook, signed. There is no scheduler. Sourcedocs.e2b.dev/sandbox/auto-resumeread 2026-11-03 |
||
| 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. |
||
|
BlaxelKnowledge Grounding & RAG No retrieval index or knowledge base over the customer's content comes with the platform. Agent Drive, volumes and the sandbox filesystem hold files an agent's code reads, and retrieval built with LlamaIndex or another framework runs as the customer's own hosted agent. Sourcedocs.blaxel.ai/agent-drive/overviewread 2026-11-05 |
||
|
E2BKnowledge Grounding & RAG There is no retrieval structure over the customer's content, since E2B runs the agent's code. Files uploaded to a sandbox or volume are storage the agent's code can read, not an index a query returns, and the MCP gateway's tools reach outside knowledge sources owned by others. Sourcee2b.dev/llms.txtread 2026-11-03 |
||
|
Memory & State Persistence Ability to persist context across a run, conversation, workflow, user, team, or longer-term memory layer. |
||
|
BlaxelMemory & State Persistence A sandbox on standby keeps its memory and running processes and resumes in about 25ms, even months later, and snapshots, forks and archives copy or preserve that state. Volumes keep data for years, and Agent Drive, free while in beta, gives several agents one shared filesystem for files and session context. This is machine and file state the developer manages, not a memory layer with a stated scope and lifetime that a buyer can review or delete as memory. Sourcedocs.blaxel.ai/sandboxes/forkread 2026-11-05 |
||
|
E2BMemory & State Persistence An agent's working state carries across sessions. A paused sandbox resumes exactly as it was, with filesystem and memory, running processes and loaded variables, and is kept until it is killed. Snapshots and forks copy that state, volumes, in private beta, keep files across sandboxes, and code contexts keep interpreter variables between executions, which the agent's code reads to continue its task. This is machine state the developer manages, with no memory layer of stated types or scope that can be reviewed, edited or deleted as memory. Sourcedocs.e2b.dev/sandbox/persistenceread 2026-11-03 |

| Control & trust | ||
|
Human Oversight & Guardrails Approval steps, consent checkpoints, escalation rules, structured guardrails, policy constraints, and pause/resume controls. |
||
|
BlaxelHuman Oversight & Guardrails There is no approval step or escalation to a person for an agent's actions. Domain, method and path filters on the egress proxy limit what code can reach, and guardrails come from a partner integration with Rippletide, but nothing pauses an action until someone reviews it.

E2BHuman Oversight & Guardrails There is no approval step, consent checkpoint or escalation to a person for work inside an E2B sandbox. Egress control (allow and deny lists for each sandbox, a proxy the customer runs that fails closed, and access tokens on public URLs) limits what an agent's code can reach, but that is isolation the developer configures, not a point where a person reviews the agent's action.

BlaxelSecurity, Identity & Governance Blaxel holds SOC 2 and ISO 27001, with reports in its compliance portal, and signs HIPAA Business Associate Agreements as a monthly add on. Workspace admins create policies, invite and remove users, change permissions and manage integrations, while members work with agents, MCP servers, model APIs, jobs and sandboxes and can only read policies. SAML single sign on and SCIM directory sync are configured at the account level, service accounts give machines their own credentials, and domain capture controls how a company's users sign in.

E2BSecurity, Identity & Governance E2B holds SOC 2 Type II, with the report under NDA in its trust center at trust.e2b.dev, and signs HIPAA Business Associate Agreements on Enterprise plans. Its controls protect the sandbox. Every sandbox is its own Firecracker microVM with its own kernel, egress can be allowed or denied for each sandbox, secrets are injected at the egress proxy so no sandbox holds them, and public sandbox URLs can require an access token. Who inside a customer's organization can do what has no published control yet, since E2B lists single sign on, SCIM and role based access as planned. Sourcee2b.dev/securityread 2026-11-03 |

Observability & Auditability Traces, logs, execution histories, metrics, audit events, and debugging detail for production agent behavior. |
||
|
BlaxelObservability & Auditability Agents hosted on Blaxel are traced with no setup. Each trace breaks a request into spans for LLM calls, tool calls and agent steps with their inputs and outputs, a sampled 10% of executions are kept and any run can be forced to keep its trace, and custom spans add detail. Logs cover request status, builds and custom output, metrics show request rates, latency percentiles and token use, and the managed egress proxy audits every request an agent sends out. Sourcedocs.blaxel.ai/observability/overviewread 2026-11-05 |
||
|
E2BObservability & Auditability The record covers the sandbox, not the agent. Every lifecycle event is available through an events API and delivered as a signed webhook, sandbox metrics report CPU and memory use, template builds keep logs, and on Enterprise OpenTelemetry metrics and logs export to the customer's OTLP endpoint. Prompts, tool calls, retrieved knowledge and outputs cannot be inspected step by step in E2B, since the agent's reasoning runs outside the sandbox, and there is no audit log of user actions apart from the runtime.

Deployment & Data Residency Deployment modes and options, including SaaS, dedicated cloud, VPC, on-prem, hybrid, local runtime, and self-hosting. |
||
|
BlaxelDeployment & Data Residency Sandboxes run in one chosen region (Oregon, North Virginia, London or Frankfurt), while agents, MCP servers and jobs spread across the regions a policy allows, and location policies stop any resource from running in a prohibited region. Private networking connects the customer's VPC through private endpoints, and a bring your own metal option runs the sandbox runtime on servers in the customer's own VPC, connected to Blaxel's control plane.

E2B Cloud defaults to Google Cloud us-west1, and AWS us-west-2 and us-east-1 and Google Cloud europe-west1 and asia-southeast1 are available on request on every plan. With BYOC on AWS, Google Cloud or Azure on Enterprise, the data plane runs in the customer's own cloud account.

Model Flexibility & Routing Ability to work across multiple foundation models, route tasks to different models, or let buyers bring their own providers and keys. |
||
|
BlaxelModel Flexibility & Routing The customer chooses the models its agents call. The model gateway puts OpenAI, Anthropic, Mistral, Cohere, xAI, DeepSeek, Azure AI Foundry and Hugging Face models behind one endpoint with central credentials, policies can cap tokens, and any agent or coding tool running in a sandbox can use whichever model it is configured for.

E2BBrowser & Computer Use Agents control real desktops hosted by E2B. E2B Desktop sandboxes are Ubuntu machines with an XFCE desktop and preinstalled applications, and the Desktop SDK gives the agent screenshots, mouse, keyboard and scroll, with a live VNC stream so a person can watch.

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.
