An open-source tool released by developer JUk1-GH automates the discovery, validation, and price collection for ChatGPT Team and Business promotional codes across 17 countries, uncovering discounts up to 71% off the standard $50/month pricing. The project has gained 330 GitHub stars as developers and ChatGPT users seek ways to reduce subscription costs.
Four-Phase Automated Discovery System
The scanner operates through a systematic four-phase process. The Discovery Phase generates candidate codes by combining known company names with country codes following the pattern companyname + countrycode (e.g., thinkingmachinesth). The Validation Phase tests these candidates against OpenAI's eligibility API using Clash Verge for geo-switching across 34 codes in 17 regions. The Price Collection phase automatically extracts discount metadata and converts prices to USD, while the Payment Phase generates Stripe checkout links for direct purchasing.
The toolkit includes five Python scripts: discover_codes.py for batch code generation, auto_scan.py for automated verification and pricing, open_stripe.py for payment link generation, verify.py for single-code testing, and configuration management via TOML. Requirements include Python 3.9+, Clash Verge proxy client with API compatibility, and a ChatGPT account with valid accessToken.
34 Active Promotional Codes Discovered Across Major Markets
The project identified approximately 34 active promotional codes across major markets. Codes exist primarily from mid-market MSPs and AI tool companies rather than enterprise providers. Notable limitations include expired codes like geccogb, region-specific eligibility requirements, and token expiration causing false negatives during validation.
For users paying $50/month for ChatGPT Team, a 71% discount represents $35.50/month savings or $426 annually, making this tool financially valuable. The automated discovery and validation process saves hours of manual testing across different regions and code combinations. The tool addresses a gap where OpenAI doesn't publicly list available promotional codes, requiring manual discovery or insider knowledge.
Technical Implementation and Community Response
The builder, identified by GitHub username JUk1-GH, originally published the research on the Linux.do community before releasing the open-source implementation. The strong community response—330 GitHub stars—indicates significant interest from developers and cost-conscious ChatGPT users.
While the tool automates discovery of publicly available promotional codes, questions exist about whether circumventing geographic restrictions via VPN violates OpenAI's terms of service. However, according to OpenAI's official guidance on ChatGPT Plus promotions, promotional codes represent legitimate offers obtained from partners, and the tool simply makes discovery more efficient.
