Carbon Ads is one of the better-known names in developer advertising. It serves native placements on a curated network of technical and design sites, which makes it a natural consideration for developer tools, design products and infrastructure companies.
Exact publisher lists, formats, pricing and onboarding can change, so this page does not pretend to quote them. If Carbon is on your shortlist, ask for the current media kit and minimums.
RoketAd is pre-launch. It is being built for indie software — SaaS, AI tools and developer products — with a self-serve model, category-based placement and prepaid packs. There is overlap in the technical audience. The difference is in focus and buying process.
Both are niche networks. The comparison is about fit, not superiority.
