Fio

Fio is an independent software publisher distributing its work through GitHub, currently offering a single product called FylloCode. FylloCode is a desktop application designed to make AI coding agents function as reliable teammates rather than unpredictable assistants. Its core idea is a structured workflow that splits every code change into distinct stages: Task, Proposal, Apply, and Archive. In the Task stage, a unit of work is defined; in the Proposal stage, the agent's intended changes are laid out for human review; only after approval are changes actually applied to the codebase, and completed work is then archived for traceability. This gated, review-first approach addresses a common pain point in AI-assisted development, where autonomous agents may introduce unreviewed or hard-to-track modifications. The application falls into the developer tools and developer productivity category, sitting alongside code review utilities, AI pair-programming aids, and workflow orchestration software. Typical use cases include individual developers who want tighter control over agent-generated edits, small teams experimenting with AI coding assistants while maintaining code quality standards, and engineering environments that require an auditable record of automated changes. By inserting human checkpoints between an agent's intent and its execution, FylloCode helps users adopt coding agents with greater confidence, reducing the risk of silent regressions and keeping accountability with the developer. The product reflects a broader trend in software tooling toward human-in-the-loop automation, where AI handles the labor of code generation while people retain final authority over what enters the repository.
