Pick any combination of languages, editors and operating systems and get a merged .gitignore — real rules, not a summary, with duplicate lines (like "dist/" appearing in both a language and an editor template) collapsed automatically instead of repeated.
Generated locally, nothing uploaded
Any combination of language, editor and OS templates.
Duplicate lines shared between templates appear only once.
Paste the result into a .gitignore file at your project root.
Several templates share common rules — both the Node and Python templates ignore a "dist/" directory, for instance. Concatenating templates naively repeats those lines once per template selected; this tool tracks every line already added and skips exact duplicates, so combining five templates does not produce five copies of the same rule scattered through the file.
Yes — check any combination, and the merged result deduplicates lines shared between templates automatically.
They are a real, stable subset of what each language/tool actually needs ignored — not the full upstream template verbatim, but not an invented summary either.
No. The file is generated entirely in your browser.
Generate cryptographically random UUID v4 or time-ordered UUID v7, in bulk.
Encode and decode Base64 with correct UTF-8 handling, including the URL-safe alphabet.
Generate ULIDs — sortable by creation time like UUID v7, but Crockford Base32 instead of hex.
