Where each one falls short

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

KoboToolbox

  • The free Community plan caps at 5,000 submissions a month and 1 GB of file storage, and any form collecting photographs exhausts storage long before it exhausts the submission count.
  • The Starter paid plan allows only 1,000 submissions a month for $21, which is fewer than the free nonprofit tier, so a small commercial user pays more for less than a charity gets free.
  • Eligibility for the free plan depends on Kobo's assessment of your organisation and purpose, which introduces an approval step that a consultancy working on behalf of an NGO may not clear.
  • Self-hosting is genuinely possible but the stack is substantial to deploy and maintain, so a ministry choosing it for data residency reasons takes on real infrastructure staffing cost.
  • Analysis and reporting inside the platform are basic compared with dedicated tools, so most serious use exports to Excel, Power BI or statistical software, and that export step is where data governance often gets loose.

VWO

  • Growth plan restricted to 1 workspace and 0 custom attributes
  • Single Sign-On (SSO) and API access limited to Enterprise tier only
  • Growth plan offers only 8-hour first response time for support
