Thanks for the suggestion. We started out supporting popular saas tools as it will increases the chances of people trying out. We currently support kafka as a destination. Also could you give example of some of the OSS destinations you have in mind?
Sorry about the docs. Haven't done much testing on smaller screens yet.
Currently we have 14 destinations available for use.
Salesforce, Hubspot, Intercom, Google Ads, Mailchimp, Google Sheet, Sendgrid, Marketo, ActiveCampaign, Kafka, Customer.io, Google pub/sub, Mixpanel, Rest API.
