Reddit Username Checker

Bulk-check whether Reddit usernames are available or already taken. Feed in a list of usernames and get back a clean, structured result for each one — available or not. Duplicates and invalid names are filtered out automatically, so you never waste a check.

What does Reddit Username Checker do?

This Actor takes a list of Reddit usernames and tells you, for each one, whether it can still be registered. It runs entirely on the Apify platform, so you get API access, scheduling, integrations, proxy rotation, and run monitoring out of the box — no browser or local setup required.

Why use Reddit Username Checker?

• Brand protection — confirm your brand or product name is still free before someone else takes it.
• Username hunting — find short, clean, or on-brand usernames that are still available.
• Bulk research — check hundreds of names in one run instead of typing them one by one.
• Automation — schedule recurring checks and wire the results into your own tools via the API.

How to use Reddit Username Checker

1. Open the Actor and go to the Input tab.
2. Paste your list of usernames (one per line). The u/ or @ prefix is optional and case doesn't matter.
3. Keep the residential proxy setting on (recommended).
4. Click Start and wait for the run to finish.
5. Download your results from the Output tab.

Input

Field	Description
Usernames to Check	The list of usernames to verify (up to 1000 per run). u/ and @ prefixes are optional, case is ignored, and duplicates are removed before checking. Unique names beyond the first 1000 are skipped.
Proxy Configuration	Proxy settings. Residential proxies are strongly recommended — Reddit blocks datacenter traffic.

Example input:

{
    "usernames": ["spez", "my_cool_unclaimed_name_2026", "u/SomeBrand"],
    "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] }
}

Output

Each username becomes one row in the dataset. You can download the dataset in various formats such as JSON, HTML, CSV, or Excel.

[
    {
        "username": "spez",
        "available": false,
        "error": null
    },
    {
        "username": "my_cool_unclaimed_name_2026",
        "available": true,
        "error": null
    }
]

Data table

Field	Type	Description
username	text	The normalized username that was checked.
available	boolean	true if the username can be registered, false if taken, null if it couldn't be checked.
error	text	Populated only for invalid usernames or names that couldn't be checked.

How much does it cost?

Cost scales with the size of your list — you're billed per result, and each username produces exactly one result. Duplicate and invalid names are filtered before any checks run, so you only pay for real, unique names.

Tips

• Keep the default residential proxy setting on — Reddit is aggressive about blocking non-residential traffic.
• If you see rows with an error, re-run just those usernames.
• Valid Reddit usernames are 3-20 characters, letters, numbers, underscores, and hyphens only — anything else is flagged as invalid without spending a check.

FAQ, disclaimers, and support

Is this legal? The Actor only checks public username availability — the same information anyone sees on the Reddit signup form. It does not access private data or log into any account. You are responsible for complying with Reddit's Terms of Service and applicable laws.

Why is a username marked unavailable when the profile doesn't exist? Reddit reserves many names (banned, deleted, or held) even when no public profile is visible. Availability reflects whether the name can be registered, not whether a profile currently exists.
