Remote job board with no registration and no charge to search. It has a dedicated Part-Time Jobs page and categories including IT and software development.
Why I recommend it: Free and simple. As with any board, apply only on the employer's own site and never pay to apply.
Subscription job board for remote, part-time and flexible jobs. Job seekers pay a membership fee for full access.
Why I recommend it: This one costs money. A third-party review put plans at $6.95 a week up to $179.40 a year, with a 30-day money-back guarantee on some plans, but I could not confirm current prices on FlexJobs's own site. Check before you pay.
Event staffing company for live events, sports and concerts.
Why I recommend it: From your list. I couldn't confirm pay, W-2 status, hiring locations or how to apply: its page I could read has only a company description. Check the site's careers or staff signup before you rely on it.
Freelance transcription, captioning and subtitle work. Posted pay ranges from $0.40 to $1.10 per audio minute for transcription, paid weekly by PayPal, with a short skills test and sample.
Why I recommend it: Rev's page says applications are waitlisted because of high volume. Per-minute pay can work out to modest hourly earnings depending on how fast you work. No minimum hours.
Online platform for teaching live classes to learners ages 1 to 18. Outschool keeps a 30% teacher fee; payment comes by PayPal 7 to 13 days after a class starts. Open to teachers in the U.S. and several other countries.
Why I recommend it: A strong fit if you can teach coding, math or study skills to kids. You set your own classes and price, but you keep 70%, and you pay your own taxes. I took the fee and pay timing from Outschool's teacher FAQ.
