Software & Developer Tools
Software referrals pay in product credit rather than cash — the trade-off for working anywhere in the world. Our two picks are Railway, a developer platform-as-a-service that drops $20 of deploy credit on a new account with no card required (the referrer then earns 15% of the account's spend for life once it starts paying), and Wispr Flow, an AI voice-dictation app that gives a free month of Pro at sign-up. Both are two-sided, both serve UK sign-ups in their own checkout, and neither captures a card to start the new joiner's free tier. We score the real value of the credit, how quickly it lands and how dependable the programme is.

Software questions
Is the Railway $20 credit still available in 2026?
Yes — $20 of deploy credit is the standard incentive when a new account signs up via a referral. It applies automatically, needs no card and doesn't expire by date; it is simply consumed as you use compute. Once your usage passes $20 and your first invoice settles, the person who referred you starts earning 15% of your spend.
What does the Wispr Flow referral give a new user?
A free month of Flow Pro at sign-up, with no card required to start the trial. The person who referred you earns their own free Pro month once you've dictated 2,000 words on Pro — roughly a week of ordinary use.
Do UK customers pay in pounds for these?
It varies. Some tools bill UK customers in GBP; Railway and Wispr Flow are priced in US dollars, so your bank applies the conversion. The referral rewards themselves — free credit, a free month — are applied at the product layer and aren't affected by exchange rates.
