  • Each has a real cost: Greenphire the standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.; SurveySparrow the free plan allows 75 responses per quarter, 3 active surveys and 10 questions per survey
  • They diverge on capability: Greenphire covers ClinCard, SurveySparrow covers Survey creation.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Greenphire

  • The standalone greenphire.com site now redirects to Suvoda and the brands have been integrated, so buyers are contracting with a randomisation and supply vendor and should expect cross selling rather than an independent payments specialist.
  • Nothing is published on price, and the typical shape of a platform fee plus per participant and per transaction charges means the cost of a trial is not knowable until enrolment is known.
  • Payment method availability varies sharply by country, so a global protocol may end up with card payments in some regions and slow manual processes in others, which undermines the retention argument that justified the purchase.
  • Sites bear the administrative work of enrolling participants and triggering payments but are not the buyer, so adoption depends on the sponsor mandating it and site resistance is a real implementation risk.
  • Participant payments create tax reporting obligations that differ per jurisdiction, and the tooling helps but does not remove sponsor liability, so legal and finance review is required in every country the trial runs in.

SurveySparrow

  • The free plan allows 75 responses per quarter, 3 active surveys and 10 questions per survey
  • The Basic and Starter plans include a single user; extra users cost $49 per user per month
  • Responses are metered per month and additional responses or API calls require a custom quote from sales
  • Custom branding requires the Business plan
  • CSS customisation, auto translation, Key Driver Analysis and HIPAA compliance are Enterprise only
  • The advertised savings of up to 40 percent require annual billing rather than quarterly
