Why this Secret Santa generator?
- Supports exclusions (NG pairs) and optional groups (same household/team).
- Reveal recipients one by one (the full table stays collapsed by default).
- Secure randomness by default via crypto.getRandomValues.
- Copy, download (TXT/CSV/JSON), and share settings-only URLs.
How to use (3 steps)
- Paste participants (one per line).
- Add exclusions / groups if needed.
- Generate, then reveal each giver’s recipient.
Create assignments fast
Secret Santa tool
Paste names, add constraints, and generate a one-to-one assignment.
Formats: Alice,Bob / Alice -> Bob / tab-separated. Mutual is recommended.
Advanced options
Example: Eve+Frank means they won’t be assigned to each other (when “avoid same group” is ON).
Seeded mode is for reproducibility. It is not intended for cryptographic secrecy.
Result
Reveal (recommended)
Select a giver and reveal their recipient. This reduces accidental leaks compared to showing all pairs at once.

Advanced URLs can include names/constraints only if you explicitly enable them (privacy warning).
FAQ
How do I use it?
Paste participants, add exclusions/groups if needed, click Generate, then reveal recipients one by one.
What is an exclusion (NG pair)?
An exclusion is a forbidden pairing (e.g., couples). The generator will not assign those pairs.
What are groups?
Groups let you avoid giving within the same household/team (A+B+C per line).
Why can’t it find a solution?
Constraints may be too strict. Relax exclusions/groups, add more participants, or turn off “avoid 2-cycles”.
What is seeded mode?
Seeded mode is for reproducible results with the same seed. It is not intended for cryptographic security.
Are names stored or uploaded?
No. Everything runs locally in your browser. Share URLs are settings-only by default.
