The short version

  • Only LimeSurvey has a free tier, so it costs nothing to try first.
  • Each has a real cost: Customer.io essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that; LimeSurvey self-hosting shifts patching, backups and PHP upgrades onto your own team, and neglected installations become a security liability holding participant data.

Where each one falls short

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

Customer.io

  • Essentials plan caps at 5,000 profiles (people and objects) and 1,000,000 monthly emails, with overages billed at $0.12 per 1,000 emails beyond that
  • Standard and Premium tiers show custom pricing only, and Enterprise is negotiated rate, so three of the four published tiers require a sales conversation
  • Monthly plans accept credit card only; annual billing via invoice (ACH/wire) requires the annual commitment

LimeSurvey

  • Self-hosting shifts patching, backups and PHP upgrades onto your own team, and neglected installations become a security liability holding participant data.
  • The default interface and themes look dated beside Typeform or Jotform, which measurably lowers completion rates on consumer-facing surveys.
  • Cloud plans are capped on responses per period, so an unexpectedly successful field wave can force an upgrade in the middle of data collection.
  • Serious theming and layout changes require template and CSS work rather than a visual designer, so agencies often budget developer time per project.
  • Support on the free edition is community forums only, and paid support is a separate purchase, which is a poor fit for teams with no technical staff.
