Tool round-ups that name the catch
7 lists covering 59 tools for coding practice, interview prep, certifications and the job hunt itself. Each entry carries the exact free-tier limit, the exact price in the currency the vendor charges, and one line on who it is not for. Where a figure was not published, we say that rather than guess it.

All round-ups
How a tool earns a place
- Somebody opened it. Pricing page included. The date that happened is printed next to the entry and is moved only by a checker that successfully re-fetched the page.
- Exact numbers or nothing. A free tier is described by its actual limit, a price by its actual figure and currency.
- Every entry names who it is wrong for. A list where everything is excellent tells you nothing and is the easiest kind to fake.
- Nothing is bought. No affiliate links, no commissions, no paid slots; where a competitor beats us, the page says so.
- Dead links fail the build, and any entry unverified for 90 days goes back on the review list.
Questions people actually ask
How are these lists put together?
Every tool on every list was opened and read before it was written about — pricing page included — and each entry records the date that happened. We record the exact free-tier limit and the exact price with currency, and where a figure was not published we say so instead of estimating it. Across 7 lists that covers 59 tools.
Does OnJob earn money from the links on these pages?
No. There are no affiliate links, no referral commissions and no paid placements anywhere in these round-ups. The link pipeline that tags paid links rel="sponsored" has an empty sponsored-host list because there is nothing to tag. OnJob makes money from its own subscriptions, not from sending you elsewhere.
How often do these lists get updated?
A checker re-fetches every outbound link, follows redirects, and flags any entry whose verification is more than 90 days old. Dead links fail the build. An entry it cannot reach keeps its old date and stays on the review list, so the date printed next to a tool always means somebody confirmed it was still there.
Do you recommend competitors over OnJob?
On these pages, often. A round-up where the publisher always wins is worthless, so where a competitor is genuinely the better answer for a use case we say which one and why. OnJob appears only where it does something the alternatives do not.
