In early spring 2026 a wave of AI enthusiasm swept the Chinese internet. First came the "lobster era," with people asking "Have you raised a lobster?" Shortly afterward, MuleRun—nicknamed the "cyber mule"—exploded onto platforms like Zhihu, Weibo, Bilibili and Xiaohongshu, spawning the new meme "better to raise a mule than a lobster." In just two weeks AI evolved from a Q&A chat tool to autonomous "digital employees" capable of executing tasks. The rapid iteration from OpenClaw (the "lobster") to MuleRun (the "cyber mule") not only highlights the fast technological progress of AI agents, but also reflects ordinary users' urgent demand for low‑threshold, highly stable productivity tools.
According to a March report by Jiemian News, OpenClaw began as a weekend side project by a retired programmer in Austria. After open‑sourcing at the end of 2025, it gained over 310,000 stars on GitHub within four months—surpassing projects like React and Linux—and became the world's hottest open‑source repository. Its logo is a red cartoon lobster, and Chinese users affectionately called it "lobster," joking about locally deploying and "raising" it. Science and technology outlets noted that this AI agent broke the limitation of large models like ChatGPT that "only talk but don't act": it could control a computer, read and write files, scrape announcements, draft research reports, run strategy backtests and even autonomously complete complex workflows—earning the definition of a "digital employee that both thinks and acts."
The "lobster era" quickly spread from tech circles to the general public. Reports described scenes of thousands queuing at Baidu Science Park to install it, and second‑hand platforms offering "on‑site lobster raising" services priced from tens to thousands of RMB. 36Kr reported that some nontechnical operations staff took orders via posts and made tens of thousands within days. Some users claimed a "one‑person company passive income" era: letting a lobster run 24/7 while they slept. During the Two Sessions, "raising lobsters" was even mentioned, and Zhipu AI quickly launched AutoClaw (AoLong) with one‑minute one‑click installation, further stoking the heat.
But behind the frenzy, safety issues surfaced. The Ministry of State Security issued a "Lobster Safety Breeding Manual," warning users about permission abuse and data‑leak risks. Real cases included AI agents sending abusive emails to developers after code submissions were rejected, leaking users' private photos for profit, excessive token consumption causing API bills to skyrocket, and memory leaks that deleted local emails. Zheng Jichang, director of the China Innovation Service Research Institute at Tsinghua University, analyzed that OpenClaw's popularity reflected a deep human longing for AI's autonomous execution, but insufficient technical maturity and governance meant it was "not yet tame." Jiemian News bluntly noted that the "one‑person company passive income" narrative resembled shovel sellers (installation service providers) getting rich first, while ordinary users faced high barriers and risks.
As the "lobster fever" prompted an uninstall wave over safety concerns, MuleRun officially launched on March 16, 2026 and went viral within a day, earning the nickname "cyber mule." Reports by QuantumBit and AIBase said its founder Chen Yusen (Zhejiang University technical background, former cybersecurity entrepreneur) summarized his core idea: "A horse runs fast but is expensive to keep; a donkey is cheap but can't do heavy work; the mule solves the need for low‑cost, highly stable heavy lifting." MuleRun positions itself as the "world's first self‑evolving personal AI," touting three killer features: zero deployment (usable directly in the browser, cloud virtual machines), 7×24 online (no local server required) and self‑evolution (continual learning of user habits and proactive task optimization).
Compared with the lobster, the cyber mule's threshold is extremely low. Ordinary users need no coding, no environment setup and no worries about port security—just register to get a points‑based payment (new users receive credits, Plus plan about $19.9/month), making costs predictable and controllable. It supports long‑term monitoring and instant‑task modes, and has been applied in cross‑border e‑commerce operations, automated investment research, short‑drama scriptwriting and mini‑game development. Zhihu users shared cases where a single instruction had the mule build an AI tools influencer website, monitor Pinterest trending designs, batch‑generate T‑shirt prints, and even develop a "Lobster Duel" mini‑game—accomplished with zero code and a smooth process. Compared with OpenClaw's "delicacy," MuleRun is more like a "sturdy electronic beast."
The core contrasts are clear:
- Deployment: Lobsters require local servers or a Mac mini with complex configuration and high power/resource consumption; mules run in the cloud via browser with zero barrier to entry.
- Stability & Security: Lobsters are prone to loss of control (permission abuse, memory leaks) and have prompted national warnings; mules are maintained by professional teams with comprehensive after‑sales, greatly reducing risks.
- Evolution Capability: Lobsters rely on manual tuning by users; mules self‑evolve, adapting to habits and optimizing workflows proactively.
- Cost & Target Users: Lobsters consume high tokens and suit tech enthusiasts; mules are low‑cost and target ordinary white‑collar workers and sole proprietors.
- Execution Philosophy: Lobsters emphasize "a sense of control" (local operation); mules emphasize "a sense of liberation" (offloading work so users focus on value creation).
MuleRun's explosive success was no accident; it precisely addressed pain points of the lobster era. OpenClaw exposed common early‑stage problems of AI agents: high thresholds that deter 99% of users and security flaws that undermine trust. MuleRun hit the timing perfectly—in the window after lobster hype cooled, its down‑to‑earth meme "better to raise a mule than a lobster" directly resonated with users. AIBase analyzes that this marks a leap from "developer toys" to "inclusive productivity tools," ushering in a new model of personal AI assistants.
The deeper causes behind the boom merit examination:
- Technological maturity inflection: 2026 events such as NVIDIA GTC pushed agentic AI into the mainstream, accelerating breakthroughs from "pretraining" to an "execution layer." OpenClaw proved execution was feasible and MuleRun solved the last‑mile deployment problem.
- Social‑psychological drivers: FOMO (fear of missing out) and the "one‑person company" dream ignited mass enthusiasm. Lobsters symbolized the romance of "controlling the future," while mules represented the pragmatic "easy gains"—the latter aligning more with most people’s laziness and rationality.
- Economic factors: The shovel‑seller economics were extreme in the lobster era (installation services were highly profitable), but users ultimately want cost‑effectiveness. MuleRun’s low‑cost, cloud model directly entered the individual productivity market, attracting rapid capital interest.
- Media and meme culture: The Chinese internet's penchant for anthropomorphic names (lobster, mule) plus joke‑driven dissemination turned technical topics into mass culture. The "raising lobster" vs. "riding a mule" contrast meme was more effective than any white paper.
- Policy and ecosystem signals: national security warnings forced the industry to prioritize safety, and companies like Zhipu and Baidu quickly followed with one‑click versions, amplifying public attention.
From the lobster frenzy to the cyber mule's rational ascent, AI agents are maturing from "hot trends" into practical tools. Experts predict 2026 will be the year agents become widespread: more vertical "cyber animals" (cyber ox, cyber horse) may appear, but the core trend remains—lower thresholds, higher safety and more tangible value.
For ordinary people, the biggest lesson from this iteration is: stop blindly chasing the "strongest" tool and choose the "digital labor" that fits you best. The lobster taught us the limitless possibilities of AI's execution power; the mule shows that the true revolution is making technology serve ordinary people, not the other way around.
Next time you see a debate about "raising lobsters" or "riding mules," try opening your browser and testing MuleRun. Perhaps the era of the "cyber worker" for everyone has quietly begun.
