Decoding a search query
What people are really searching when they type "https://claude.ai/referral/" since:2026-05-27
It looks cryptic, but it is just X advanced-search syntax. A quoted URL plus a since: date is how people fish for Claude referral links that were posted recently enough to maybe still work. Here is what those links are, why the fresh ones disappear in minutes, and the one mechanical detail that ties them to a native Mac client.
Direct answer (verified 2026-06-21)
A claude.ai/referral/ link is a single-use Claude Code Guest Pass. A Claude Max subscriber mints it with the /passes command (3 per account), and it grants the recipient a 7-day Claude Pro trial. Passes are first-come-first-served and never replenish, so a link posted in public is usually already redeemed by the time you find it. That is exactly why the search bolts on a since: date: it filters out the graveyard of dead links and shows only the newest posts, which have a slim chance of still being live.

The Guest Pass, in four numbers
Once a pass is redeemed it cannot be reissued. That non-replenishing design is what makes the hunting game so brutal: a popular link is a race against everyone else running the same query, and the link dies the moment one person wins.
Where the link comes from: a command inside Claude Code
Every claude.ai/referral/ URL is generated by a slash command that lives inside the Claude Code agent loop. A Max user runs /passes and the loop hands back the links. There is no separate referral dashboard for this; the minting happens in the same agent runtime that does the coding.
Illustrative of the /passes interaction. Codes shown are placeholders, not real passes.
This is the detail nobody else writing about these links mentions, and it is the only part of this page you cannot copy from somewhere else. Because the links are born inside the Claude Code agent loop, any tool that wraps that loop is sitting next to the exact mechanism. Fazm, a native macOS app, does exactly that: its ACP bridge pins the official adapter @agentclientprotocol/claude-agent-acp at version 0.29.2 in acp-bridge/package.json. The agent loop running behind a Fazm window is the real Claude Code, not a reimplementation.
If you do land a pass, it works in a native client for free
A redeemed Guest Pass gives you a real Claude Pro session for 7 days. The question that follows is always: where do I actually use it without immediately hitting an API bill? The honest answer is to sign in with the same OAuth flow Claude Code uses, so usage draws from the Pro plan instead of metered API credits.
Fazm does this literally. Its bridge file acp-bridge/src/oauth-flow.ts reimplements Claude Code's setup-token flow: it opens https://claude.ai/oauth/authorize with the user:sessions:claude_code scope, so the session runs against your plan allowance. No API key, no per-token charge. Fazm itself is free and open source. The deeper mechanics of why an OAuth session avoids the credit meter are covered in a separate guide on Claude usage credits.
The hunt versus what actually gets you Claude Pro
Refreshing a search feed for a live pass is a lottery against the single-use, non-replenishing design. It is worth being clear-eyed about the two paths.
Two ways people try to get a Claude Pro trial
Running the quoted-URL search with a recent since: date, clicking link after link, hoping one of the 3-per-account passes has not been claimed yet.
- Passes are first-come-first-served and never replenish
- Popular links are claimed within minutes of posting
- Links on non-claude.ai hosts are phishing risk
- No guarantee any public link is still live

Questions people actually have about these links
Frequently asked questions
What does the search "https://claude.ai/referral/" since:2026-05-27 actually do?
It is X (Twitter) advanced-search syntax. The quoted string forces an exact-phrase match on posts that literally contain the URL prefix https://claude.ai/referral/, and the since:YYYY-MM-DD operator restricts results to posts published on or after that date. People run it to surface recently posted Claude referral links, on the theory that newer posts are likelier to have an unclaimed pass behind them. The same operators work on Google too, though Google's date filtering is less precise than X's since: token.
What is a claude.ai/referral link?
It is a Claude Code Guest Pass. A Claude Max subscriber generates it with the /passes command in Claude Code (or under Settings, Claude Code tab). Each link grants the recipient a 7-day Claude Pro trial, including the current models and Claude Code. Anthropic's own guidance is that legitimate referral links always live on the claude.ai/referral/ domain, so any link on a different host is a phishing risk.
Why do public referral links almost never work by the time I click them?
Each Max account gets only 3 passes, and once a pass is redeemed it is gone and does not replenish. A pass posted publicly is effectively first-come-first-served against everyone else running the same search. The popular links get claimed within minutes. That single-use, non-replenishing design is the whole reason people bolt a since: date onto the query: they are trying to filter out the thousands of already-dead links from months ago.
Does the sender get anything if I redeem their pass?
Yes. If you keep a paid Pro subscription after the 7-day trial ends, the person who shared the pass earns $10 in Claude credit applied to their next bill. With 3 passes that caps at $30 in referral credit per Max account. You will be asked for payment details to start the trial, but you are not charged unless you stay subscribed past day 7.
Is there a different claude.ai/referral that shows up in my website analytics?
Yes, and it is unrelated to Guest Passes. If you run a site, claude.ai/referral can appear as a referrer in your analytics when a visitor clicks an outbound link that Claude surfaced inside a conversation. That is citation traffic, not a rewards program, and it has nothing to do with the shared-link hunting this page is about. If you are searching the quoted URL on X, you are looking at Guest Passes.
Where does Fazm fit in if I am hunting for a Claude trial?
Fazm is a native macOS app that wraps Claude Code through ACP. It does not hand out passes and is not affiliated with Anthropic's referral program. The connection is mechanical: the /passes command that mints these referral links runs inside the Claude Code agent loop, and Fazm pins that exact loop (the @agentclientprotocol/claude-agent-acp adapter, version 0.29.2) in its bridge. Fazm signs in through Claude Code's own setup-token OAuth flow, so whatever Claude plan you have, including a trial off a redeemed pass, works inside Fazm and draws from your plan rather than burning API credits.
If I do redeem a pass, can I use it in Fazm with no extra cost?
A redeemed pass gives you a real Claude Pro session for 7 days. Fazm authenticates with the same OAuth scopes Claude Code uses (it reimplements setup-token, hitting claude.ai/oauth/authorize), so usage runs against that Pro allowance. There is no API key and no metered API spend involved. Fazm itself is free and open source, so the only thing you are spending is the plan you already authenticated.
