A curated list of 15 small apps (Linktree, TinyPNG, Bitly, Day One, Splitwise, Typeform, Calendly, Toggl Track, Sortly, Content Snare, Trello, Notion, Slack, Statuspage, YNAB clones) that can be vibe coded with an AI agent instead of paying for subscriptions. Each links to a build guide from the author's Vibecode It Yourself catalog of 109 project ideas, with scoped prompts, realistic time estimates for a basic version versus a full product, and explicit non-goals to keep the first build small. The guides support stacks like AHA, Next.js, Laravel, or Ruby on Rails, and the piece recommends starting with simpler self-use tools (Linktree, image compressor) before attempting ambitious ones like a Slack clone.
