Remote OK is on of the largest and most popular remote job boards in the world, created by Nomad List founder, Pieter Levels in 2015. They share their site traffic publicly, and get 600-800k visitors per month.
The site's wide reach alone makes it a popular choice for employers hiring remotely. Where the site falls behind, however, is in its complete disregard for user experience and design.
Remote.io is a remote job board founded in 2019 by Tony Territo. In 2020, the site merged with another remote job board called Nomadify. Remote.io is now owned by a company called Innovation Labs. In 2021, they launched a "2.0" rebrand on Product Hunt which included the addition of a basic category search feature.
The site is very simple and easy-to-use. They have 500+ remote jobs with basic search functionality, allowing job seekers to search by category. However, the search function does not behave as you'd expect. For example, when we searched "design", it returned mostly software engineering roles. For employers, you can log in and manage jobs from a simple dashboard.
