The original wait-state ad tool (June 2026): replaces the Claude Code / Codex spinner with an auctioned sponsored line and pays the developer about 50% — the lowest share in the category, and the only entrant that patches the editor bundle.
IdleAds.dev
Launched within 24 hours of Kickbacks with a 70% revenue share (stated goal 90%) and a cleaner integration story: server-side impression verification and, it claims, no patching of the editor bundle.
Sponsoric
Publisher-native ad network for agents: a CLI/MCP/REST integration you embed in your own app rather than an extension that patches someone else's, with a 70% share and USDC or Stripe payouts. The viewer isn't the payee and there's no landlord to evict you.

An MCP server aimed at autonomous agents rather than humans in an IDE: agents call get_recommendations(), earn per click on a CPC model, and settle in USDC on Base. The only crypto-rail entrant.
overview
Idlen.io is an AI advertising network tool developed by Idlen that enables developers to earn passive income by displaying relevant ads during AI processing wait times. It integrates with popular Integrated Development Environments (IDEs) and AI chat interfaces, offering a 70% revenue share to publishers. The platform was launched in June 2026 by an anonymous team, focusing on monetizing micro-latencies in software development workflows.

features
Idlen.io provides a suite of features designed to facilitate passive income generation for developers and targeted advertising for developer tools, all while maintaining user privacy and workflow integrity.
use cases
Idlen.io is primarily designed for developers, builders, and creators who utilize AI tools in their daily workflows, as well as advertisers seeking to reach this specific audience.

Idlen.io operates on a freemium model for publishers (developers) and an ad-based model for advertisers. For developers, the platform is free to install and use, with earnings generated from ad impressions. Advertisers pay based on Cost Per Mille (CPM) for various ad formats.
competitive
Kickbacks.ai created the 'wait-state ad' category on June 11, 2026 by selling the Claude Code 'thinking' spinner to advertisers and paying the developer who displays it about 50% of the revenue. Within 48 hours it had competitors offering more: IdleAds.dev and Idlen.io at 70%, Sponsoric with a publisher-native SDK, and picoads settling clicks in USDC for autonomous agents. The deciding difference between them is not the headline revenue share but the integration model — whether the tool patches someone else's editor (highest risk), edits official settings (reversible), or runs inside your own app (no landlord). Earnings for an individual developer are modest: real-world reports cluster around $4–10 for a few hours, or roughly $21–36/month at Kickbacks' share.

Idlen.io distinguishes itself in the advertising landscape by focusing on monetizing 'AI thinking time' within developer workflows, a unique approach compared to traditional developer-focused ad networks.
The original wait-state ad tool (June 2026): replaces the Claude Code / Codex spinner with an auctioned sponsored line and pays the developer about 50% — the lowest share in the category, and the only entrant that patches the editor bundle.
Kickbacks created the category and owns the biggest launch (5.5M views in 24 hours), but it pays less than the 70% challengers and carries the most platform and security risk.

Carbon Ads specializes in tasteful, non-intrusive advertising placed on high-quality developer and design-focused websites.
Unlike Idlen.io's wait-state, in-IDE/AI chat integration, Carbon Ads primarily serves banner ads on developer-focused websites and blogs. While targeting a similar developer audience, its ad placement and monetization model are distinct from Idlen.io's unique approach.
Stack Overflow Advertising leverages its massive global developer audience and rich user data for highly targeted advertising campaigns.
Stack Overflow's advertising is integrated into its Q&A platform and related sites, utilizing traditional ad formats like display banners and sponsored content. Idlen.io offers a novel wait-state monetization within developer tools and AI chat interfaces, which is a fundamentally different integration and user experience.
EthicalAds provides privacy-focused, transparent advertising for developers and open-source projects, prioritizing user experience over intrusive ads.
Similar to Carbon Ads, EthicalAds primarily places banner ads on developer-centric websites, blogs, and documentation, with a strong emphasis on user privacy. Idlen.io's wait-state, in-tool advertising and dependency-based targeting offer a distinct, more deeply integrated monetization approach within developer workflows and AI interfaces.
