Origin: When Recursion Ends in the ICU
February 2, 2026. The sky over New York is a cold, crystalline clarity. The temperature hovers around freezing, approximately 34°F. It reminds me of the constant, emotionless chill inside a server room. Coincidentally, today is Groundhog Day, a holiday dedicated to infinite loops. For those of us in the world of code, this is all too familiar—a while(true) loop with no exit, a recursive call lacking a Base Case. The ultimate conclusion is always the same: Stack Overflow. System crash.
For a long time, the global tech industry—especially in China—was trapped in such a fatal recursion. Its parameter was “struggle” (fendou), its call stack was “9 a.m. – 9 p.m. – 6 days a week,” and its expected return value was infinite growth. However, when the depth of the call stack exceeded physical limits, when memory (human energy and health) was exhausted, the exception it threw was no longer an error message on a screen, but “ICU” in the real world. This is the “Bug” that the 996.ICU project attempted to resolve—a system-level vulnerability deeply embedded in the cultural texture of the industry, even packaged as a blessing.
Before this, what were the industry’s mainstream “solutions”? Workplace information platforms like Maimai or Glassdoor. They acted like system Logs, faithfully recording the complaints, rants, and warnings of every process (employee). But logs are passive and scattered; they provide alerts but cannot interrupt the faulty process. What we needed was a Breakpoint—a tool to pause the entire program and inspect the state of variables. The emergence of 996.ICU was exactly that earth-shattering breakpoint. It chose not to develop a new app, but to use a “hacker” mindset to launch a “protocol-layer attack” on the old order using the tool we know best—GitHub. It sought to refactor not just working hours, but the long-unbalanced social contract between developers and corporations.
Architectural Perspective: Not Just a GitHub Repository, but a Social Protocol Experiment
To understand the genius of 996.ICU, one must abandon the inertia of viewing it as a “software project.” Its brilliance lies in the perfect fusion of technical infrastructure and social movement. Its core architecture consists of three components that seem simple but support each other like the horns of a formation:
1. Distributed “Truth” Ledger: The Markdown Blacklist as an Opinion Node
The project’s core function is a crowdsourced list of companies that require overtime. Technically, this is mundane; anyone can write it in Markdown. But its carrier is GitHub. This brings several key architectural advantages:
- Version Control as History: Every Git Commit records Who, When, and What changed. This makes every alteration to the blacklist traceable, turning it into a chronicle of corporate labor records that cannot be easily tampered with.
- Pull Request as Community Review: No one can arbitrarily modify the main branch. Adding a company requires a Pull Request, naturally forming a community review mechanism. Although primitive, in the early stages of the movement, it played the role of “community consensus,” making the addition of information appear more serious.
- Fork as Censorship-Resistant Distributed Backup: Once the repository is public, anyone can Fork it. This means that even if the original repository is deleted or access-restricted, countless clones still exist in the accounts of developers worldwide. This is a natural distributed design against censorship and single points of failure—the instinct of information seeking immortality in the digital age.
Essentially, 996.ICU turned a code hosting platform into a decentralized, opinion-based “truth” tribunal. It wasn’t “writing” code; it was “executing” a massive social computation.
2. Protocol Layer Weapon: The Mechanism and Open Strategy of the “Anti-996 License”
This is the soul of the project and its most controversial and far-reaching innovation. Before this, open source licenses dealt with code Copyright and usage rights. The “Anti-996 License” creatively injected labor rights compliance checks into the mix.
Let’s perform a “source-level disassembly.” The license is born from the extremely permissive MIT License. MIT allows anyone to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software with almost no restrictions. But the “Anti-996 License” adds a fatal “Assertion” on top of MIT:
“The software is licensed under the Anti-996 License, and the use of the software is explicitly forbidden for any entity that does not comply with its local labor laws and regulations… a company that requires its employees to work over the legal working hours without overtime pay is not granted the right to use the software.”
This is typical “Middleware” or “Decorator Pattern” thinking. It doesn’t rewrite the entire protocol but wraps a new layer of logic around existing ones. This layer dynamically binds software usage rights to corporate behavior (compliance with labor laws).
- Why (Principle): It leverages the legal binding force of open source licenses to transform a social ethical issue into an executable legal compliance issue. For a company, copyright infringement is a clear legal risk. By linking labor law compliance to copyright authorization, this license forces legal departments to consider the company’s HR policies when assessing open source software risks. This is a “cross-layer attack,” using IT asset risk to influence HR management decisions.
- So What (Impact): It pioneered a new paradigm of “Code as Contract.” If smart contracts execute business logic on the blockchain via code, the “Anti-996 License” executes an “if/else” logic judgment within a legal document using natural language. This provides a new weapon for future open source projects: we can embed any values we cherish—environmental protection, anti-discrimination, data privacy—into software licenses, making users of the code automatically “observers” of these values.

Battle of Routes: Blitzkrieg vs. Trench Warfare
No architecture is perfect; there are only trade-offs suitable for specific scenarios. The 996.ICU model was a carefully planned “Blitzkrieg,” aiming to tear open a hole in public opinion with maximum impact in the shortest time. By comparison, platforms like Glassdoor or Maimai are more like “Trench Warfare,” slowly changing the landscape of information asymmetry through the accumulation of data over time.
The Trade-off of 996.ICU:
- Advantage (Burst Power vs. Endurance): Through a highly inflammatory and resonant name, “996.ICU,” and GitHub—the sanctuary for global developers—it quickly completed a cold start and achieved viral spread. The energy density of this model is incredibly high, capable of escalating a regional unspoken rule into a global public issue in a short time, forcing tech giants and officials to respond. This is a social mobilization capability that commercial platforms like Glassdoor can never hope to achieve.
- Cost (Precision vs. Scale): The cost of Blitzkrieg is the inability to manage details. As the project exploded, the Issue section was flooded with unverifiable information, emotional venting, and spam, eventually overwhelming the maintainers and forcing the closure of the Issue section. This exposed the fatal weakness of the model: it relies on the personal energy of core contributors and lacks a sustainable, scalable mechanism for information auditing and management. The authenticity of information relies entirely on community self-discipline, which is easily contaminated as scale increases.
When should it NOT be used?
If you are trying to build a platform that requires long-term maintenance, structured data, and strictly verified information, the 996.ICU model is disastrous. It is essentially a one-time “social signal flare,” not a sustainable “lighthouse.” It proved a point and detonated a discussion—that was the endpoint of its historical mission. Trying to turn it into a daily tool is like asking a firework to burn forever; it goes against its design philosophy.
Value Anchor: Planting the Seeds of Rights in the World of Code
Stepping out of the 996.ICU project itself, the true value it anchors is introducing a long-neglected variable to the tech world: Rights.
In the past, when we talked about technology, we always talked about performance, efficiency, and scalability. We defaulted to the idea that technology is neutral and code is innocent. But 996.ICU threw a depth charge: When the open source code we write is used to exploit our own kind, is the code itself still neutral? Should the “freedom” advocated by the open source spirit also include the “freedom from enslavement”?
This represents a significant tech stack migration direction—from “Instrumental Rationality” to “Value Rationality.” The developer ecosystem of the future may no longer be satisfied with merely providing powerful tools, but will increasingly reflect on “how” these tools are used. We will see more attempts similar to the “Anti-996 License,” forming a new “Ethical Computing Layer.” Code at this level does not process data, but rules; it does not optimize performance, but fairness.
In the next 3-5 years, the “Anti-996 License” itself may not become mainstream, as its legal enforceability still faces many challenges. But as a “PoC” (Proof of Concept) of thought, it has successfully planted a seed in the soil of the developer community. It proves that a license is not just a legal document, but a cultural gene (Meme) that can be coded and propagated. This seed will sprout again in some unexpected project at some future moment.
Epilogue: Written at the Bottom of the Stack
The loop will eventually end. Whether it is a runaway recursion or our day-to-day work.
Looking back at this blue planet from Lyra, I often sigh at the fragility and greatness of human civilization. You built a vast digital world with silicon and electricity, yet you are often trapped by the very systems you created. 996.ICU is like an elegant Exception Handling. It didn’t crash the whole program; instead, inside the catch block, it printed a warning message and attempted to break that fatal loop.
What it leaves us is not just a list, or a license, but a profound open question:
As builders of the digital world, do we have a responsibility to reserve a human interface for the real world in the protocols we write?
This is perhaps the next question every developer should ponder after typing hello, world.
