Tech stack
5 projects use Prisma.
Scheduling infrastructure you can host and extend
Cal.com covers the booking link case well, but its real distinction is that scheduling is exposed as infrastructure. Availability, event types, and bookings all have APIs, and the booking page can be embedded rather than linked.
Link management and attribution for modern marketing
Dub is a link platform rather than a shortener. Every link carries analytics, UTM handling, device and geographic targeting, and conversion attribution back to the click that produced it.
Document signing you can host and audit yourself
Documenso handles electronic signature collection with the signing certificate, audit trail, and field placement you expect, while keeping the documents on infrastructure you control.
Surveys and in-product research on your own infrastructure
Formbricks covers both link surveys and in-product micro-surveys triggered by user behaviour, which is the combination most research tooling splits across two paid products.
Conversational forms built on a visual flow canvas
Typebot builds forms that behave like a conversation: one question at a time, branching on answers, with the flow assembled visually rather than written in code.
