From real-time API lookups to smart suggestion algorithms — here's the full picture of what happens when you search a username.
Type any handle into the search box. Live character counting and format hints appear instantly.
Our validator checks Reddit's rules instantly — length, allowed characters, reserved words — before any API call.
We query Reddit's public API in real-time to determine if the username is registered or available.
10 brandable alternatives are generated instantly using 20+ naming patterns tailored to your keyword.
Your username is rated 1–100 for memorability, brandability, and Reddit-compliance. No login needed.
When you submit a username, our tool sends a request to Reddit's public user API endpoint. Reddit responds with either a full user profile (meaning the username is taken) or a 404 error (meaning it's available).
This check happens client-side — your browser communicates with Reddit directly. No username data passes through our servers.
When your desired username is taken, our suggestion engine kicks in. It takes your keyword and runs it through over 20 naming patterns to generate 10 clean, brandable alternatives — all filtered for Reddit compliance.
Unlike random number generators, our patterns produce real, memorable handles you'd actually want to use.
Every username is rated from 1 to 100 based on a multi-factor algorithm. A high score means your username is memorable, brandable, and built to last on Reddit's platform.
The score considers length, character composition, uniqueness, and whether it avoids overly generic or number-heavy patterns that make usernames hard to remember.
Too short, too generic, heavy use of numbers, or looks like a throwaway account. Hard to remember and low brandability.
Solid username with decent length and character mix. May have minor issues like underscores or trailing numbers.
Memorable, brandable, Reddit-compliant, and unique. Ideal length, no numbers, good character variety.
| Criteria | Condition | Points |
|---|---|---|
| Length | 6–15 characters (ideal range) | +25 |
| Length | 3–5 characters (acceptable) | +10 |
| No numbers | Username contains zero digits | +20 |
| Starts with letter | First character is a–z or A–Z | +10 |
| No underscores | Username uses no underscore character | +10 |
| All lowercase | Consistent lowercase styling | +5 |
| Character uniqueness | Unique chars > 60% of total length | +10 |
| Not generic | Not on the common-word blocklist | +10 |

A 1–100 rating that tells you how memorable, brandable, and Reddit-compliant your username really is.

Fully responsive — desktop, tablet, or phone. No app to install. Open a browser and start checking.
Your browser calls Reddit's public profile API endpoint. If the profile returns a 200 response, the username is taken. A 404 means it's available.
Your keyword is sanitized (lowercase, only letters and numbers, max 12 chars) and passed through an array of pattern functions. Each pattern produces a candidate username, which is then filtered for Reddit compliance.
A deterministic scoring function runs your username against 8 weighted criteria. Points are summed and capped at 100. The score runs instantly in your browser — no server round-trip.
This tool runs entirely in your browser. We do not intercept, log, or store the usernames you type. Reddit's API is called directly from your device.
Yes — we query Reddit's live API so results reflect the actual current state. If Reddit shows a username as taken (even a suspended or banned account), we report it as taken. Format violations are caught before any API call is made.
Reddit does not free up deleted or suspended usernames. Once a username is registered, it remains claimed even if the account is deleted or banned. This is Reddit's policy, not a limitation of our tool.
In single-check mode, one at a time. In bulk mode (Bulk Check tab), you can enter up to 10 usernames at once — one per line — and all are checked simultaneously.
Yes. Whenever you check a username — taken or available — the suggestion engine generates 10 alternatives automatically. Click "Regenerate" to get a fresh batch based on the same keyword.
Reddit usernames must be 3–20 characters long and may only contain letters (a–z, A–Z), numbers (0–9), underscores (_), and hyphens (-). Spaces and special characters are not allowed. Our validator enforces all of these rules before any API call.
No. The strength score is our own rating for memorability and brandability — it's not a Reddit system. Reddit only cares that your username follows its format rules and is not already taken. Our score helps you choose a username you'll be happy with long-term.
