Software for People Who Build Things
Tools that delight
builders and creatives.
Sunday Man Ventures is a software company crafting applications and services for the people who make things — developers, designers, tinkerers, and artists. We build with intention, ship with craft, and stay out of the way.
Chat Net
A lightweight, terminal-native chat application built for speed and clarity. Chat Net strips away the bloat of Slack and Teams to deliver a focused, keyboard-first messaging experience built on the reliability of Erlang and the performance of Rust.
Vibe Board
An application for creating, curating, and sharing mood boards built for creative projects. Organize visual references, color palettes, and inspiration into living documents that communicate feeling — not just function.
Hats
Chat with multiple large language models through distinct user personas, each maintaining its own independent, long-running memory context. Switch roles, preserve continuity, and stay in character — all in one place.
Dicto
A guided naming workflow for apps and products. Describe what you're building, how you like to name things, and where it fits in the market — Dicto evaluates candidates against namespace conflicts, CLI collisions, and competing projects, then delivers taglines, wordmarks, and specimens ready to take further.
Systema
A GUI tool for building design systems at the primitive level — tokens, color, shape, and semantic rules — rather than screens. Built for developers who need design and designers who need to speak developer, Systema uses modern color science and automated contrast evaluation to produce systems with meaning, not just style.
Chu-Hi
A persistent cloud development environment built around you, not your codebase. Chu-Hi manages configurations, dotfiles, and multi-project contexts across any number of sandboxed instances — spin them up, tear them down, rebuild them — and always arrive to the same environment, wherever you are.
Deckware
Write the deck instead of designing it. Deckware turns plain markdown into a finished presentation — you focus on what you're saying, and the slides build themselves. No layouts to nudge, no boxes to align; the time you'd spend wrestling a deck goes back into the content.
Terminal Shop
Shop from a terminal. Terminal Shop is a keyboard-first storefront for niche designer brands, hard-to-find goods, and curiosities — browse, search, and check out without leaving the prompt. A command line for commerce, legible to humans and agents alike.
All Sunday Man Ventures products are designed with care, built without compromise, and available to anyone in the world. We are proud to build in the United States.
