Who should pick which

  • Developer building a reliable AI agent
    Pick: Temporal AI

    Temporal's durable execution ensures the agent survives failures, with automatic retries and state capture.

  • Developer building a web-scraping agent
    Pick: KERNEL

    KERNEL provides fast browser spin-up, stealth, and proxy support ideal for scaling web interactions.

  • Team orchestrating microservices with rollbacks
    Pick: Temporal AI

    Temporal's Saga pattern and compensating transactions handle failure recovery in distributed systems.

  • AI startup needing computer-use agent infrastructure
    Pick: KERNEL

    KERNEL's sub-30ms browsers and Playwright/CDP support are built for AI computer-use agents.

  • Enterprise needing both durable workflows and browser automation
    Pick: Temporal AI

    Use Temporal for workflow orchestration and KERNEL for browser tasks; they are complementary.

Frequently Asked Questions

KERNEL vs Temporal AI: which should you choose?

Choose Temporal AI if you need fault-tolerant, durable orchestration for multi-step AI agent workflows or microservices that survive failures. Choose KERNEL if you need ultra-fast, headless browser infrastructure for AI agents that interact with web pages, with stealth and proxy support. They solve different problems and can be complementary.

Can Temporal AI be used for browser automation?

Not directly; it orchestrates workflows but doesn't provide browser environments. You'd pair it with KERNEL or Playwright.

Is KERNEL suitable for long-running workflows?

KERNEL focuses on fast browser sessions; for durability across failures, use Temporal as the orchestrator.

Which is more cost-effective for small teams?

Temporal has a generous free tier (10k actions/mo) and self-hosted option. KERNEL free includes 1000 min/mo. Both are affordable for small projects.

Do both tools support Python?

Yes, Temporal has a Python SDK; KERNEL supports Playwright (Python) and CDP, so Python agents can interact with KERNEL browsers.

What are the latest updates for each?

Temporal: usage-based billing, custom roles pre-release. KERNEL: CLI extensions, computer-use for claude-sonnet-5.

Can I use both together?

Yes, Temporal can orchestrate a workflow that invokes KERNEL browsers as activities for reliable, fault-tolerant web automation.

Which has better observability?

Temporal provides full execution visibility UI. KERNEL offers live session viewing and MP4 recording of browser sessions.

Are they open source?

Both are open source: Temporal (MIT), KERNEL (Apache 2.0).
