How we compare

alter.sg is only useful if you can trust the numbers. Here is exactly how every comparison on the site is put together.

1. 1

   We gather the facts from the source

   Every price, fee and feature comes from the provider’s own website — not from third-party aggregators. Each tool page links the exact source page we checked.

2. 2

   We convert everything to SGD

   Prices are shown in Singapore dollars so you can compare like for like, with GST treatment noted where it applies.

3. 3

   We re-verify on a cycle

   Each page carries a “Verified” date. An automated check flags any tool whose data is more than 90 days old so it gets re-checked.

4. 4

   We rank for the Singaporean traveller

   Recommendations are made for trips Singaporeans actually take. Coverage, price in SGD and ease of use are weighed for the destination, not a generic global average.

5. 5

   Affiliate links never move the rankings

   Some outbound links earn a commission. Rankings and verdicts are decided on the facts before any commercial relationship is considered. Tools with no affiliate programme are still listed and linked.
