Where each one falls short

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

Lambda (AWS Serverless)

  • Billed on two axes at once, $0.20 per million requests plus $0.0000166667 per GB-second of duration, so memory settings change the bill as much as traffic does
  • Provisioned concurrency, used to avoid cold starts, is charged separately at $0.0000041667 per GB-second whether or not the function runs
  • Ephemeral storage beyond the included 512 MB is metered
  • Lambda@Edge costs $0.60 per million requests, three times the standard request rate
  • VPC use and cross-region data transfer carry EC2 charges on top

Copilotly

  • Copilotly explicitly disclaims that its legal, medical, and financial copilots are not a substitute for licensed professional advice, which limits its use for anything requiring accountable expert sign-off.
  • The free plan caps usage at 3 copilots and 50 messages per day, pushing most real usage onto the paid Pro tier.
  • It relies on third-party foundation models (GPT-4o, Claude, Gemini, DeepSeek) rather than proprietary domain models, so answer quality is bounded by those underlying models.
  • There is no published documentation site or API, limiting integration options for developers or teams wanting to build on top of it.
  • Safari support is listed as 'coming soon' rather than available, so macOS/iOS Safari users are currently unsupported in-browser.
