Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Autonoly

  • Pricing is credit-based, so heavy web-scraping or long-running workflows can consume the monthly allowance quickly and require add-on credit packs.
  • The free plan allows 1,000 credits and three concurrent workflows a month, which is enough to trial the product but not to run anything continuously.
  • No published mobile apps (iOS/Android); the platform is web-based only.
  • Company details such as founding date, founders, and team size are not disclosed on the site, making it harder to evaluate the vendor's track record.
  • As an AI-agent-driven scraper/executor, reliability on sites with aggressive bot protection or frequently changing layouts may vary compared to purpose-built RPA tools.

Letta

  • Free tier limited to 3 stateful agents
  • Pro tier capped at 20 stateful agents
  • API Plan usage charges apply beyond base tier
