Pros
  • True agentic control of a real browser, including authenticated sessions, CAPTCHAs, and multi-tab workflows
  • Plan-first execution model with visible steps you can pause, edit, or override mid-run
  • Scheduled/recurring tasks turn one-off automations into standing jobs
  • Bundled specialist agents (deep research, image, music, code) generate deliverables, not just links
  • Eko 2.0 open-source framework lets developers extend or script custom agents
  • Generous free tier for evaluation, with an unlimited-Sparks Ultra plan for heavy users
  • Reliable, debuggable agent graphs
  • Built-in persistence + HITL
  • Production-grade
  • Tight LangSmith integration
Cons
  • Requires installing a dedicated Chromium browser rather than an extension in your existing setup
  • Underlying model provider(s) and per-task token accounting are opaque — you pay in Sparks without a clear cost model
  • Letting an agent drive logged-in accounts (banking, email, employer SaaS) raises real security and ToS-violation risk
  • Task counts on paid tiers are modest (~8-20 tasks/month on Plus/Pro) so heavy automators land on the $199.90 tier fast
  • Newer product with a shorter track record than Chrome/Edge — expect breakage on sites that change layouts or add bot defences
  • No public REST API for the hosted product; automation lives inside the desktop app or Eko framework
  • Steeper learning curve than CrewAI
  • Verbose to set up
