One Tool for All Formats: nesdit Unifies JSON, YAML, and TOML Configuration Editing

Configuration file management has long been fragmented across incompatible tools—jq for JSON, yq for YAML, and separate utilities for TOML—forcing engineers to build brittle shell scripts that scale poorly in CI/CD environments. nesdit consolidates this workflow into a single binary with jq-style queries that work declaratively across all three formats, featuring atomic writes and diff previews that eliminate common configuration drift issues. For DevOps and infrastructure teams, this represents a significant step toward safer, more testable infrastructure-as-code practices.
