E2B vs Toki: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of E2B and Toki — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
E2B
E2B
Open-source cloud platform that gives AI agents secure, isolated sandboxes and real-world tools via SDKs and managed sandboxes.
Key features
- Secure Cloud Sandboxes: Isolated Linux virtual desktop sandboxes that run AI-generated code and agent actions with containment, file system controls, and process isolation for safe execution.
- Multi-language SDKs: Official Python and JavaScript/TypeScript SDKs for creating, starting, controlling, and retrieving executions from sandboxes, enabling easy integration into apps.
- Desktop Sandbox (Computer Use): Virtual desktop environment and UX that lets agents interact with real-world tools (GUI, shell, files) through natural language and programmatic control.
- Streaming API & Real-time Interaction: Websocket/streaming interfaces to stream agent decisions, logs, and UI actions in real time between LLMs, sandboxes, and frontends.
- Dashboard & Management: Web dashboard for provisioning sandboxes, managing API keys, viewing logs, and administering enterprise settings and access controls.
- Open-source Ecosystem: Multiple Apache-2.0 repositories (SDKs, examples, apps, templates) and cookbooks that accelerate building and customizing agentic workflows.
- LLM & Provider Agnostic Integration: Works with various LLM providers (including open-source models) and supports provider-specific integrations for agent orchestration.
- Developer Examples & Templates: Reference apps (Fragments, Surf, open-computer-use) and a cookbook to bootstrap agent applications, personas, and production flows.
- Secure isolated cloud sandboxes for running AI-generated code
- Python SDK (pip package: e2b-code-interpreter) for sandbox lifecycle and code execution
- JavaScript / TypeScript SDK (npm: @e2b/code-interpreter) for sandbox lifecycle and code execution
- Virtual desktop sandbox environments with UI/frontend integration (e.g., Surf project)
- Streaming API for real-time frontend-backend communication and agent actions
- Dashboard built with Next.js 15, React 19 and Supabase for managing sandboxes and API keys
- CLI tooling and environment variable based API key (E2B_API_KEY) for auth
- Open-source license (Apache-2.0) and public repos (code-interpreter, surf, fragments, cookbook)
- Examples/cookbook with integrations for multiple LLMs and agent frameworks
- Integration examples with OpenAI for computer-use agents
Best for
- Code Interpreting in Apps: Embed the E2B SDK to execute and evaluate model-generated code safely within a controlled sandbox for code-assistant features.
- Autonomous Agent Workflows: Run agentic workflows that interact with a virtual desktop (browsers, terminals, files) to perform tasks like data extraction or automation.
- Secure Execution of Untrusted Code: Execute LLM-produced scripts or tool calls in isolated sandboxes to prevent lateral movement and protect enterprise resources.
- Interactive Data Analysis: Allow an LLM to run data-processing scripts (Python/R) inside a sandbox to produce plots, reports, and reproducible outputs for analysts.
- Productized Agent Services: Build customer-facing agent products (e.g., automated assistants, document processors) using managed sandboxes and streaming responses.
- ML/Research Experimentation: Rapidly prototype model behaviors and code-interpreting features across LLM providers using open-source examples and templates.
- Embed code-interpreting capabilities into AI applications to execute and evaluate generated code
- Run agentic workflows that need real-world tooling access in an isolated, auditable environment
- Build virtual desktop experiences where agents interact with a UI and perform tasks via natural language
- Prototype and test LLM-driven automation that requires file system, network, or process-level operations safely
- Enterprise deployments requiring sandboxed compute for compliance and security while using LLMs
Toki
Orion Arm
AI executive assistant that reaches out to attendees to book meetings, architects your day, and tracks tasks across synced calendars.
Key features
- Attendee Coordination: Toki contacts meeting attendees itself to find a time that works for everyone, removing the availability back-and-forth entirely.
- Scheduling Links: Calendly-style booking links for cases where a shareable link is simpler than having Toki negotiate a time.
- Proactive Day Architecture: Toki plans the day ahead of time, balancing protected deep-work blocks against urgent demands rather than just recording events.
- Natural Multimodal Input: Voice notes, screenshots, quick texts, and half-formed requests are all accepted and connected into the right events, reminders, and tasks.
- Personal Preference Memory: Toki learns how you work, how you plan, and what you prefer, improving its scheduling decisions the longer you use it.
- Triggers: Tell Toki a condition to watch — a price, a deadline, a release date — and it monitors and pings you when the condition is met.
- Conflict Resolution: Smart scheduling detects and resolves calendar conflicts across synced calendars instead of double-booking.
- Call Me Alerts: For things you truly cannot miss, Toki escalates from a notification to an actual phone call.
Best for
- External Meeting Booking: Getting a meeting with several outside attendees on the calendar without a chain of availability emails.
- Deep Work Protection: Having an assistant proactively reserve focus blocks and defend them against incoming requests.
- Multi-Calendar Consolidation: Keeping personal iCloud, work Google, and Outlook calendars coherent in one view without manual duplication.
- Capture on the Move: Sending a voice note or a screenshot of a flyer and having it become a dated event or reminder.
- Deadline Monitoring: Setting a trigger on a stock price, a product release, or an application deadline and being pinged when it fires.
- Critical Reminder Escalation: Receiving a phone call rather than a dismissable notification for appointments that cannot be missed.
