Why a sponsorship here works
Privacy-first, so it gets seen
Your slot is a static image + link from our own CDN — no third-party scripts, no cookies, nothing for privacy tools, strict CSPs, or ad-blockers to strip out.
A pure developer audience
979 tools for engineers — formatters, converters, validators, crypto, CSS. High-intent developers, exactly who most dev-tool and infra products want.
Fast + non-intrusive
One tasteful slot: no interstitials, no auto-play, zero layout shift. It respects the reader — so it reflects well on you.

Who actually visits
The traffic here is people mid-task. Somebody formatting a JSON payload at the point of debugging it, checking a contrast ratio while building a component, decoding a JWT to find out why an auth call failed. That is a narrow, high-intent audience rather than a broad one, which is why a developer-tool or infrastructure product lands far better here than a general consumer offer would.
It also means the visit is short. Nobody browses a utility site; they arrive from a search with a specific problem and leave when it is solved. A placement works as a repeated impression against a relevant audience, not as a destination people linger on, and it is worth pricing on that basis.
Why the slots work the way they do
One sponsor slot per page, rendered as static markup in the same build as everything else. No third-party ad script, no real-time auction, no behavioural tracking, no interstitial, and nothing that moves after the page has loaded. The site's entire premise is that your data does not leave the browser, and a bidding tag would contradict that on every page it appeared on.
The practical consequence for an advertiser is that a placement cannot be retargeted or audience-segmented. What it can be is contextual — a database product beside the SQL tools, a font service beside the typography ones — which for this audience is usually the more useful targeting anyway.
What will not be accepted
Anything that would embarrass a reader who trusted the recommendation: cryptocurrency and trading schemes, adult content, gambling, lead-generation products that exist to resell contact details, and anything whose landing page misrepresents what the product does. Affiliate arrangements are disclosed as affiliate arrangements.
This is a small site and its only real asset is that people believe what is on it. A placement that damages that is a bad trade at any price, which is why the answer is sometimes no.
