Breadcrumb is an AI plugin for developers on the Mac. It remembers your screens, meetings and AI sessions so your assistant has the context it needs, and gives you control over AI rules, shortcuts and scopes. Everything stays on your Mac, encrypted, with no account. It connects to AI tools over MCP and is free.

Helo is an email API and SMTP service for sending your product's emails, built by a lean, independent team with years of experience in email delivery. Their focus is getting your emails into the inbox so you don't have to think about it. You can start sending in minutes and only pay for what you use.

rhun is a lightweight code editor for Windows, Linux and macOS, written in assembly so it stays small and fast while AI does the heavy lifting elsewhere. It includes tabs, syntax highlighting, fuzzy search, an optional Vim mode, a terminal, Git, agents and themes. It is open source under the MIT licence and installs with one command.

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.

Talkthrough MCP is an open-source, local-first MCP server that turns screen and meeting recordings into evidence an AI agent can use. Recordings go in; transcripts, keyframes, OCR text, speaker labels and wall-clock timestamps come out. Because it runs locally, recordings stay on your machine, and AI agents connected over MCP can work with what was said and shown. The source code is on GitHub.

SubmitraX lets you collect form submissions without writing or running a server. Create a form endpoint in seconds, point your form at it, and get notified by email or Slack the moment someone submits. It is built for designers, small teams and anyone who needs responses without touching a backend, with built-in honeypot spam protection and integrations. Setup takes under five minutes, with a free tier and no credit card required.

SanityCheck automates UI and UX testing with AI agents. Add a URL, describe the test in a sentence or two, and the agents open real browsers and test your app like an actual user: for example adding an item to the cart, checking out and verifying the order confirmation. You can watch tests live and replay every click, with no SDK, CI config or test framework to set up. Tests can run automatically on every deploy from GitHub, GitLab or Vercel, and there is a free tier.
