Pros and cons

DeepSeek

Pros

  • Web chat and mobile apps are free
  • API output costs from $0.60 per 1M tokens (Flash, off-peak), well below most frontier providers
  • Open weights for V4 and earlier models on Hugging Face
  • 1M-token context and 384K max output on both API models
  • API works with both OpenAI and Anthropic SDKs and several coding agents

Cons

  • Peak-hour API rates are double the off-peak rates on weekday mornings UTC
  • deepseek-v4-pro does not support vision input
  • No image generation
  • Data is processed by a company based in China, which some organizations cannot accept

Fellou

Pros

  • Shows an editable plan before executing, with approve, pause and stop controls on each step.
  • Combines browser automation, deep research and local computer control in one app.
  • Displays estimated Spark cost before a workflow runs, according to a reviewer.
  • Free tier and a $19/month entry plan make it cheap to try.
  • Open-source Eko framework (MIT) from the same team for custom agents.

Cons

  • Reviewers report it can loop or stall on complex or dynamic layouts and cannot reliably get past CAPTCHAs.
  • Credit-based pricing: the Free plan's 1,000 Sparks cover only about 4 tasks, and cost varies with workflow length.
  • No mobile app found; desktop only.
  • Page context is processed by cloud AI, which security commentators flag as an attack-surface and privacy concern.
