Free Developer Tools

15 open-source tools — 11 Python CLI utilities + 4 Rust-powered apps. Free forever. No signup, no strings attached.

📦 Core Utilities

kw-batch-renamer Bulk rename files using patterns, regex & sequential numbering. Add prefixes, suffixes, apply case transforms, and number files with zero-padded sequences. Dry-run mode to preview changes before applying.
--prefix --suffix --lower --upper --padding --start-number --dry-run --verbose
GitHub ↗ Download
kw-folder-organizer Auto-sort files into category folders by type or extension. Supports Images, Videos, Audio, Documents, Archives, Code & Other. Handles filename collisions with numeric suffixes. Non-recursive — processes top-level files only.
--dry-run --verbose
GitHub ↗ Download
kw-project-cleaner Remove build artifacts, cache folders & junk files from dev projects. Targets node_modules, __pycache__, bin, obj, .vs, .idea, dist, build, .DS_Store, Thumbs.db. Shows size estimates before deletion.
--dry-run --verbose
GitHub ↗ Download
kw-gitignore-builder Generate .gitignore files from predefined templates for Python, Node, .NET & PHP. Always includes OS junk patterns. Composable — combine multiple language templates in one file. Protected by default.
--python --node --dotnet --php --all --force --verbose
GitHub ↗ Download

🔍 Audit & Snapshot

kw-file-indexer Recursively scan a directory and generate a structured file catalog in JSON, CSV, or plain text. Includes file metadata: name, path, size, modified & created dates, extension. Filter by extension, size range, or recursion depth. Optional MD5/SHA-256 hashing per file. Summary stats show total files, size breakdown by extension. Ideal for audits, backups, and digital forensics.
--format --output --hash --exclude --ext --min-size --max-size --depth --stats
GitHub ↗ Download
kw-folder-snapshot Capture timestamped folder state snapshots with full file metadata (size, last modified, path). Optional SHA-256 hashing for content-level change detection. Exclude patterns, limit scan depth, and label snapshots. Built-in --list to browse saved snapshots and --compare to diff two snapshots side-by-side. Output as JSON for automation or archiving.
--output --hash --exclude --name --depth --list --compare
GitHub ↗ Download
kw-diff-snapshot Two modes: compare two directories to detect added, removed, or modified files with size/hash/timestamp analysis. watch mode monitors a directory for live changes with configurable polling interval. SHA-256 hashing for accurate content-level diffs. Save reports to JSON or text. Essential for deployment verification and incremental backups.
compare watch --hash --exclude --output --summary --ignore-times --interval
GitHub ↗ Download
kw-hash-generator Generate MD5, SHA-1, SHA-256 checksums for file integrity verification. Process single files or entire directories. Memory efficient (1MB chunked reading). Pipe-friendly — results to stdout, progress to stderr.
--md5 --sha1 --sha256 --all --output FILE --verbose
GitHub ↗ Download

⚙️ Dev & Productivity

kw-env-generator Generate .env files from 9 built-in templates: general, node, python, django, flask, docker, database, aws & firebase. Merge multiple templates into a single file. Convert .env.example into a real .env with --from-example. Interactive prompts for values, or use --non-interactive for CI/CD pipelines. Reduces config errors across teams.
--template --output --list --merge --from-example --non-interactive --overwrite
GitHub ↗ Download
kw-command-logger Track terminal commands with timestamps, working directory, and optional tags. Four subcommands: log to record a command, show to display history (filter by tag, last N entries, table or JSON format), export to save full log as JSON, and clear to reset. CSV-backed storage for easy integration with scripts and CI/CD audit trails.
log show export clear --tag --last N --format --log-file
GitHub ↗ Download
kw-file-productivity-pack 4 tools in 1 pack: PDF Text Extractor (page ranges, PyPDF2), Clipboard Manager (persistent history, quick copy), Duplicate Finder (SHA-256 based, min-size filter, safe delete with --dry-run), File Type Analyzer (extension stats by size/count, table/JSON/CSV output).
