Developer tool marketing and the ad-blocking audience, revisited
Your audience blocks ads and distrusts copy on principle. What still reaches them is narrow, and most of it depends on claims they can check themselves.
Developer tool marketing has a problem no other category has quite as sharply: the audience blocks the ads, distrusts the copy, and has the technical means to verify anything you claim. Every tactic that works on a general audience by asserting something confidently fails here, because a meaningful share of readers will go and check.
That sounds like a disadvantage. Treated correctly it is the opposite, because it eliminates competitors who cannot survive being checked.
What actually reaches this audience
Sponsored slots on things they chose to read. Developer newsletters, documentation sites, and technically-focused publications. These work because they are not intercepting attention, they are appearing inside something already opened deliberately. Ad blockers do not touch a sponsor line rendered as part of the page.
Being the answer in a search that still resolves to links. Specific technical queries — an error string, an API's edge case — remain unusually resistant to summarisation, because the answer is long, conditional and version-specific. This is one of the few remaining places where good documentation is also good distribution.
Other developers. Word of mouth from someone who used it is worth more here than in any other category, and it is the only channel that survives the audience's scepticism intact. It cannot be bought and it can be earned, mostly by the product being good and the docs being honest about limits.
Open source presence. Not as a marketing tactic — the audience detects that immediately — but as a genuine artefact. A useful library, a well-written issue response, a benchmark somebody else can rerun.
What does not reach them
Display retargeting, most social advertising, anything with the words "unlock" or "supercharge", and case studies with no numbers in them. Not because developers are unusually cynical, but because they have unusually good tools for detecting the gap between a claim and a measurement, and the category has trained them to look.
The corollary is uncomfortable for anybody buying media: a substantial fraction of your impressions are never rendered, and the platform bills you for them anyway. That is not fraud, it is how the counting works, and it makes this audience expensive in a way the reported CPM does not show.
Why "checkable" is the whole strategy
Here is the reframe worth taking away. In a market where the audience verifies claims, the cost of making a checkable claim is the same as the cost of making an unverifiable one, but the return is much higher — because unverifiable claims are discounted to zero by the people you most want.
That has specific consequences for what you publish:
- Benchmarks that include the methodology and the losing cases, not just the win.
- Pricing on the pricing page, in numbers, with no "contact us" tier at the bottom if you can avoid it.
- Limitations stated in your own documentation, before somebody finds them for you.
- Performance claims with the hardware, the version and the dataset attached.
Each of those costs a little pride and buys a lot of credibility with an audience that has almost no other way to distinguish you from the four competitors making identical assertions.
Where the ad-supported networks sit now
The developer-focused ad networks have always sold the same trade: a smaller, better-defined audience at a higher CPM than general display, with a lighter ad format that a technically-minded reader tolerates. That trade is still sound, and the two obvious starting points are covered in EthicalAds alternatives and Carbon Ads alternatives for indie makers.
What changed in 2026 is the opportunity cost. When organic search reliably delivered, paid placement was optional for a devtool with good docs. With informational queries increasingly resolved before the click, the paid line is doing more of the work it used to share.
Our own board belongs in this list and is ours, so weigh it accordingly: two twelve-hour slots a day, general-audience rather than developer-specific, the first brand into an empty slot pays nothing, and every clearing price and every brand's opens and click-throughs are public. For a devtool the specific use is narrow and worth stating exactly — it answers whether cold, non-technical traffic clicks your one-line pitch, for nothing, before you pay a developer-audience CPM to find out. If the line cannot earn a click here, it will not earn one at Carbon's prices either. The scale is honestly small, and the numbers saying so are published rather than described.
The summary I would defend
Developer tool marketing is not a harder version of normal marketing. It is a different game with a smaller rulebook: appear where they already chose to be, claim only what they can verify, and let the verification do the persuading.
Most of the budget that fails in this category fails because it was spent buying attention rather than buying credibility. The audience was never going to be interrupted into a purchase, and the tools they use to prevent it are only the visible part of that.
