Hii so far I've been trying two platfors to buy offsets, I had wren and coffset, both with good results, but I'd love to hear your thoughts.

My opinion so far

Wren is been in the market for many years already, and I liked you have many alternatives to buy credits, giftcards, year upfront, business etc. The certificate sounds legit if you trust them (htey look serious by the way)

Coffset, has a similiar apporach and it's pretty new, its focused on calculation and compensation afterwards, the certificates are also great and if you dig deeper you see the retirements are legit public registries like puro earth godstandards etc.

I've tried a bit more before like Klima(i believe wren bought it) and yayzy (little bit scammy)

Idk, what other things you take into consideration, for me is basically traceability and types of offsets better than price. Oh, also both have cool dashboards.
