Which should you pick?

The two programs are not directly comparable on dollar value. Porter accepts a wider range of funding stages, while Fly.io is more targeted. Fly.io credits last longer (12 months versus 6). Note that only Fly.io is fully verified against its official page; double-check the other before relying on it. If you qualify for both, there is usually no reason not to apply to both; the programs are independent.
