Idlen

Idlen is a native developer advertising platform that places ads during AI wait time. It offers a VS Code extension for editors such as VS Code, Cursor, and Windsurf, Chrome and Firefox browser extensions, and a chat SDK for AI app builders. The platform connects developers who use AI tools with advertisers who want to reach them in their IDE, browser, and chat workflows. For developers, Idlen displays native ads from developer-tool advertisers while AI models process prompts. The homepage states that users can earn passive income without changing their workflow, with earnings paid via Stripe, PayPal, or API credits, including a 10% bonus option. Idlen also claims privacy: prompts and code stay on the user's machine and are not sent to the platform. For advertisers, Idlen targets developers based on the stack and tools they actually use. The homepage mentions a welcome offer of paying €200 and receiving €400. For AI app builders and publishers, Idlen provides a chat SDK that can be integrated in three lines of code, plus a sandbox to preview which ad would serve. Idlen positions itself as privacy-first and zero-latency, with ads loading only during AI processing. It supports popular AI tools and environments including Copilot, ChatGPT, Cursor, Windsurf, Replit, Claude, V0, Bolt, and Lovable. Pricing details are not fully specified on the homepage, though an advertiser welcome offer is listed.

Problem solved

Idlen addresses the unmonetized time users spend waiting for AI models to respond. Developers and AI tool users lose attention during model processing, while advertisers struggle to reach developers contextually in their IDE and browser workflows. Idlen inserts native ads into that wait time, letting developers earn passive income, advertisers target by developer stack, and AI app builders add a monetization layer with a few lines of SDK code.

Use cases

Developers earn passive income while waiting for AI coding assistants to generate responses
Advertisers place native developer-tool ads inside IDEs and browsers
AI app builders integrate @idlen/chat-sdk to monetize chat interfaces
Teams pool earnings from shared developer AI usage
Users preview how ads would appear via a chat sandbox
Advertisers target developers by their actual stack and tooling

Audience

Developers
Business Users
Startups

Pros

Passive income for developers during otherwise idle AI wait time
Ads load only during AI processing, so no added latency to normal workflow
Privacy claim: code and prompts stay on the user's machine

Flexible payouts via Stripe, PayPal, or credits with a 10% bonus

Cons

Earnings depend on ad demand and are not guaranteed
Requires installing an extension or integrating the SDK
Ad-supported experience may interrupt focus for some users
Limited public detail on advertiser pricing and fill rates
Platform availability may vary by country and payout method
