Proca

Open-source, GDPR-compliant petition and campaign widget you embed on your own website in minutes.

Servicefreemiumglobal

Proca is an open-source campaign toolkit that lets organisations and coalitions embed a GDPR-compliant petition or advocacy widget directly into their own website, without a new CMS to manage. Supporter data can be encrypted so only the organisation holding the key can read it, and multiple partner organisations can run a shared coalition campaign under their own branding. It can be self-hosted or used as a hosted service, and is aimed at NGOs, activists, and campaign coalitions.
