Frequently asked questions
Why contact OnSubmit?
You can contact OnSubmit to suggest a tool, report a bug, request a partnership, sponsor a page or suggest a content improvement.
Are form messages sent to a server?
Yes. The form sends the message to a Scaleway serverless function, which forwards email through Scaleway Transactional Email. The site does not store the message or display the recipient address.
Can a tool page or workflow be sponsored?
Yes. Workflows such as test data, business invoicing, data converters or security/hash can host clearly identified partnerships.
How can I suggest a new free tool?
Describe the need, target audience, formats to support, examples and related OnSubmit tools.
How should I report a security issue?
Choose the Security topic in the form and include useful reproduction steps. Do not include real secrets in the message.
