Bug bounty programs and paid coding bounties
A live directory of coding challenges you can get paid for. Every reward on CodeMarket is deposited into escrow before the challenge goes public, so the money is already there when you start. Pick a bounty, build it, let the buyer test it with a simple text input, and the reward is released the moment your solution is accepted.

How paid coding bounties work here
A bounty program is a public challenge with real money attached. On CodeMarket the person posting the challenge funds it up front, so the reward sits in escrow instead of being a promise. Developers claim the challenge, work independently, and submit a demo of the working solution. The poster tests the build in an isolated sandbox — they can run it, hit the APIs and read the logs, but they never get the source code until they accept and pay.
Some challenges carry a small entrance fee that is held separately and refunded in full if the challenge is cancelled or you withdraw before a winner is chosen. Winners take home the reward shown on each listing, paid out to their bank through Stripe.
