ShipDelta sends B2B SaaS founders and product marketing teams a weekly PDF memo on what their competitors shipped. It covers the public changelogs, docs, status pages and pricing pages you name, with plain-language notes on what changed, who cares and what to watch out for. Each memo includes per-competitor notes with citations and a source pack of URLs and fetch dates, using public sources only. A pilot covers one full cycle for up to 5 competitors, and the retainer delivers every Friday.

An app which allows you to select a route based on a set of filters. Built by people who enjoy driving, for those who drive. Built for whom the drive is the point, not the arrival. Weekend riders looking for a road they haven't done, people new to a city wanting the one their local club already knows, riders who want a record of what they've driven. Built as a PWA, can be installed on your phone directly from your browser.

Ledge is a Markdown notes app where the code blocks run. Write a shell command, code, a SQL query or an AI prompt in a note, run it in place, and the output streams in right beneath it, so your notes double as working runbooks. Notes live in workspaces with profiles for keys and database URLs, which makes it handy for API scratchpads, weekly checks and operations notes. It is free and open source, for Mac, Linux, Windows, iPhone and Android.
