A software development agency — creators of 99sync (agentic AI workflow) and tuiter (API explorer). We craft keyboard-first TUI apps, CLI tools and agentic AI workflows.

Agentic AI workflow for Neovim: project-wide search into quickfix, vibe sessions with reviewable edits, visual replace, pinned Worker, 5 CLI backends (OpenCode, Claude Code, Cursor, Kiro, Gemini).

API explorer for Neovim: write requests in .http files, send with one key over curl (non-blocking), inspect body/headers/timeline/tests, run-all with JUnit export. Zero plugin deps.

Open-source on GitHub: github.com/TheNeovimmer/99sync and github.com/TheNeovimmer/tuiter. Install via lazy.nvim, zero-bloat Lua.
