Prospero vs SendPortal: at a glance
What is Prospero?
Prospero is turning proposals from documents into instrumented, reusable assets.
Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.
What is SendPortal?
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.

Prospero
0.0MKT AUTO
Prospero is turning proposals from documents into instrumented, reusable assets.
◆ Current state
Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.
◆ Where it's heading
Two consistent threads. The first treats proposal content as a reusable asset rather than a document — catalogs, saved deliverables, locked sections and templates all reduce how much of each proposal is written from scratch. The second instruments what happens after the proposal is sent, moving from delivery and signature toward telling a salesperson which pages held attention and which were skipped. The AI writing assistant sits alongside both without yet being connected to either.
◆ Prediction
Engagement data is now captured per page but presented for a human to read; the natural next step is acting on it — alerting when a prospect revisits pricing, or feeding the analytics back into template suggestions.
SendPortal
2.5MKT AUTO
SendPortal resurfaces with a v4 patch release, its first tag since 2020.
◆ Current state
SendPortal's last tagged release before this month was v1.0.3 in July 2020. On October 22 it published v4.0.0.1, which fixes sp:install skipping migrations on fresh installs and a route-caching failure from a duplicate logout route. The changelog link implies a v4.0.0 release just before it, which isn't in the tracked entries.
◆ Where it's heading
A major version followed by fixes to the installer suggests the project is active again and new installs are being tested. With two tagged releases six years apart, there's no cadence to read yet.
◆ Prediction
If v4 is a real revival, more point releases should follow within weeks; another long silence would mean v4 was a one-off.
