The short version

  • Only KoboToolbox has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Postscript carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • They diverge on capability: KoboToolbox covers Offline data collection, Postscript covers Shopify segmentation.
  • Prices and features above were last checked on 1 September 2026.

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.

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.

Answered from the vendors’ own pages

KoboToolbox: Is KoboToolbox free?

Free for qualifying nonprofit and public good organisations under the Community plan, currently 5,000 submissions a month and 1 GB of storage. Commercial use requires a paid plan from $21 a month.

Postscript: Is Postscript only for Shopify?

It is built for Shopify and that is where its segmentation advantage lies, but headless and non-Shopify stores are supported through an SDK with more setup work.

KoboToolbox: Who funds it?

Kobo Inc is a US nonprofit funded roughly 38 per cent by grants and contributions and 62 per cent by service contracts, subscriptions and training, based on its 2024 figures.

Postscript: What is the real cost per text?

The plan rate plus carrier fees. On Starter that is about $0.015 plus roughly $0.00418 in US carrier fees per SMS, so budget close to two cents a message before discounts.

KoboToolbox: Can I host it myself?

Yes. The server stack is open source and is regularly deployed in country for data residency reasons.

Postscript: Is the Starter plan free?

No. The base fee is $0 but there is a $49 minimum monthly spend, so it functions as a $49 floor.

KoboToolbox: Are forms portable?

Yes. It uses XLSForm and ODK standards, so instruments move between Kobo and other ODK-compatible servers.

Postscript: Do I need a contract?

No. Contracts are offered but not required, and plans can be moved up or down at any time under usage-based billing.
