Workable is primarily an applicant tracking system, and its free job description generator functions as a lead-in to that broader hiring platform — which is a reasonable business model, but means the free tool is designed to convert you into a Workable user, not just hand you a draft and let you leave.
SMBkits' job posting generator has no hiring platform behind it and nothing to convert you into — enter the role details, get the draft, done. It doesn't have Workable's template library covering dozens of specific roles, but it covers the core structure any small business job posting needs: responsibilities, requirements, and a clear call to apply.
For a small business hiring one or two roles a year, adopting a full applicant tracking system to get a job description generated is a lot of platform for a small need. For a business scaling its hiring pipeline, that same platform starts paying for itself through the rest of its features — candidate tracking, interview scheduling, structured pipelines.
If you're actually planning to run your hiring process through an applicant tracking system, starting with Workable's generator makes sense since you'll end up in that ecosystem anyway. If you just need a job posting to put on Indeed or LinkedIn without adopting a new platform, the free generator does that one job.
