BidNinja Shield
BidNinja Shield is a Chrome extension that reads the job listings on Freelancer.com and marks which ones are worth a bid and which look like scams. It is listed on the Chrome Web Store. MarStudio built and runs it.
What we built
6 pieces, one business.
Open the Freelancer projects page and each job gets a badge right on the page: bid now, good fit, risky or skip. There is no separate dashboard to check.
Listings that look like scams or ghost jobs are dimmed so you do not spend a bid on them. Each card also shows a client-quality score and how crowded the job is.
Click a job and a sidebar opens with an analysis and a proposal drafted from that job's actual description, not a rotating template.
Auto-Fill puts the amount, delivery date and proposal into the bid form. You read it and press Submit yourself.
It works inside your normal Chrome session on your own Freelancer account, so there is nothing to hand over beyond installing the extension.
A free tier scores up to 30 jobs a day. Paid plans add more proposals and hands-off options, with Stripe checkout, cancel anytime and a 7-day refund.
Under the hood
Built on tools you can own.
