Stop wasting ad spend
on developers who don't care.
Traditional developer advertising is broken. You pay for impressions on developers who will never use your product. Idlen's tech stack targeting lets you reach exactly the developers who need what you're building.
- 60-80% waste - Your React tool ad shown to Python developers
- Banner blindness - Developers ignore sidebar ads (0.1% CTR)
- Wrong context - Ads interrupt reading, not coding
- 100% developers - Only verified engineers see your ads
- Tech stack match - Target by actual dependencies used
- Perfect timing - Ads during AI wait, not interrupting work
Target developers by the technologies they actually use
Our IDE extension analyzes package.json, requirements.txt, and other dependency files to understand each developer's tech stack. Target React developers, Python engineers, or Rust enthusiasts based on real project data.
Frontend Frameworks
Target developers building user interfaces
Developer installs extension
The Idlen extension scans project dependencies locally. No source code is ever accessed or transmitted.
Tech stack is indexed
We build an anonymous profile of technologies used. This enables precise targeting without compromising privacy.
Your ads reach the right devs
When you target "React developers", only developers with React in their dependencies see your ad.
Target developers by behavior and interests
Beyond tech stack, we learn developer interests from their usage patterns. Target AI enthusiasts, early adopters, or developers who frequently use specific platforms. These behavioral segments unlock audiences you can't reach anywhere else.
Show ads at the perfect moment
Timing matters. Idlen triggers ads during natural pauses in the developer workflow - when they're waiting for AI responses, celebrating a successful build, or taking a break between tasks. This contextual relevance drives 2-3x higher engagement.
