Team generator

Why this team generator?

Two ways to split: by number of teams or by team size.
Secure by default: uses crypto.getRandomValues (CSPRNG) for fair shuffling.
Optional constraints: keep together / avoid pairs (best-effort with bounded retries).
Copy, download (TXT/CSV/JSON), and share settings-only URLs (no names by default).

Generate

Split a list into random teams, then copy, download, or share settings.

Names (one per line) Tip: duplicates count as separate entries unless you enable deduplication.

Trim & remove empty lines

Deduplicate exact duplicates

Split mode Teams 2–50 teams (must be less than the number of names).

Advanced (constraints, naming, share options)

Keep together (A+B+C per line) Avoid pairs (A,B per line)

RNG Team naming

Show original indices (1..N)

Sort within each team (A→Z)

Share options (advanced)

Include names in share URL (not recommended)

Include constraints in share URL

Is it fair?

Secure mode uses crypto.getRandomValues (CSPRNG) and unbiased sampling to avoid modulo bias.

What is seeded mode?

Seeded mode is for reproducible results. It is not intended for cryptographic security.

How are duplicate lines handled?

By default, duplicates count as separate entries. Enable deduplication to remove exact duplicates.

What if constraints can’t be satisfied?

Relax constraints (increase teams/size, reduce avoid pairs, etc.). The tool will show actionable errors.

Are names stored or uploaded?

No. Everything runs locally in your browser. Share URLs do not include names by default.

Can I download results?

Yes. Download as TXT, CSV, or JSON.
