Most lists of side gigs open with the pay. That is the wrong first question.
A gig that pays $25 an hour is worth nothing to you if it needs a car. Not if you do not have one. So ask the questions in this order.
1. What do you already have?
Write down four things. Do you have a car? A computer? A smartphone? Can you stand for two hours?
Those four answers cut most lists in half. Start there, not with the pay.
2. How fast do you need the money?
Some gigs pay this week. Some take a month to clear a background check.
If rent is due, that gap matters more than the hourly rate.
3. What does it cost you to start?
A gig that needs $200 of gear is not free to try. Neither is one that eats $50 of gas a week.
Take the cost out before you compare two rates.
4. What is bad about it?
Every gig has a bad part. If a page does not tell you what it is, that page is selling you something.
Read the downsides first. If you can live with them, read the rest.
Then look at the pay
Now the pay figure means something, because you know what it costs you to earn it. That is the number to compare.
Places to start on this site, depending on what you have.
No car, but a computer and fast hands? Try typing audio for Rev or GoTranscript.
A computer and small pieces of time? Try paid studies on Prolific.
Aged 55 or over with money tight? Try a community service job with SCSEP.
A car and flexible hours? Try delivering food with Grubhub, and read the part about fuel costs first.
One long day, once in a while? Try working the polls.
You can also see every gig and filter the list yourself.
One last thing. If a page about a gig will not tell you what it pays, ask why. We checked 19 platforms and only 7 publish a pay figure.
