Deep Tide Guide: On April 21, Anthropic quietly removed its programming agent Claude Code from the $20/month Pro plan, with related pricing pages and help documents updated simultaneously. Although Growth Lead Amol Avasare claimed this was only a "small-scale test" targeting about 2% of new users, the site-wide documentation has been completely rewritten to state "Max plan only," sparking a massive backlash in the developer community. OpenAI promptly publicly stated that Codex will remain in the free and Plus plans, while the local model camp called this incident "the best time to switch to self-hosting."
Anthropic is testing developers' price tolerance limits, at the possible cost of user trust.
On April 21, some developers noticed significant changes on Anthropic's official pricing page: Claude Code was marked as unavailable (with an "X") in the feature comparison table for the Pro plan ($20/month), whereas the day before the page still stated that the Pro plan "includes Claude Code." Almost simultaneously, the wording in Anthropic's help documentation quietly changed from "Use Claude Code with your Pro or Max plan" to "Use Claude Code with your Max plan."
AI industry observer Ed Zitron first sounded the alarm on the Bluesky platform, and the news quickly sparked discussions on Hacker News, Reddit r/LocalLLaMA, and X platform.
Official Statement Calls it a "Small-Scale Test," but Documentation is Fully Rewritten
Facing the developer community's intense reaction, Anthropic Growth Lead Amol Avasare responded that day on the X platform, stating this was only a small-scale test targeting about 2% of newly registered users, and existing Pro and Max subscribers would not be affected.
However, multiple media outlets pointed out that Avasare's statement contradicted the actual situation: the feature comparison matrix on the pricing page had been updated site-wide, and the help documentation had also been modified simultaneously. These changes were visible to all visitors and did not resemble a灰度 test for 2% of users. According to The Register, as of publication time, an Anthropic spokesperson had not responded further to this contradiction.
In subsequent tweets, Avasare explained the logic behind the adjustment: when the Max plan was launched a year ago, Claude Code was not bundled with it, Cowork did not exist, and asynchronous agents running for hours were not yet the norm. Since then, Claude Code usage has surged significantly post-Opus 4, and user usage patterns have fundamentally changed. He admitted, "Usage per subscriber has increased substantially, and our current plan structure was not designed for this."
This statement actually revealed a key point: providing Claude Code access for a $20 monthly fee has become unsustainable in terms of computing costs. According to industry analysis, each Claude Code programming session consumes far more tokens than regular chat, and the computational cost of long programming sessions could be several times the subscription fee.
From $20 to $100, Developers Pushed to a Decision Point
If this change is ultimately implemented permanently, Pro users who wish to continue using Claude Code would need to upgrade to the Max 5x plan starting at $100/month, or the Max 20x plan at $200/month. The price has increased fivefold.
Developers reacted quickly and strongly. A GitHub issue titled "Breaking Change: Claude Code CLI Removed from Pro Plan Without Notice" appeared within hours.
A related post on Hacker News received over 100 upvotes and more than 40 comments in less than an hour. One user's experience was representative: he started with the $20 Pro plan in January, upgraded to $200 due to frequently hitting usage limits, downgraded to $100 due to quality drops in Claude Opus 4.6, and recently downgraded back to $20 because he was satisfied with OpenAI Codex's performance on GPT-5.4. "I went from the most enthusiastic recommender to my current state," he wrote.
The reaction on the Reddit r/LocalLLaMA community was more direct. A post titled "Anthropic removes Claude Code from Pro plan, users call it 'the best time to switch to local models'" received extensive discussion, focusing on the progress made by open-source models like Meta's Llama series, Mistral, and DeepSeek in programming capabilities over the past year, as well as the maturity of local deployment tools like Ollama and LM Studio.
OpenAI Quickly Strikes, Codex Remains in Free and Plus Plans
Competitors did not miss this window.
From OpenAI's side, an employee responsible for Codex-related work posted on the X platform: "I don't know what they're doing over there, but Codex will continue to be available in the free and Plus ($20) plans. We have the compute and efficient models to support it. For important changes, we communicate with the community in advance."
The timing and wording of this statement were highly targeted.
OpenAI's Codex, as the main competitor to Claude Code, is currently offered in the ChatGPT Plus ($20/month) plan with a usage limit of 30 to 150 messages every 5 hours, and also has basic access in the free plan. Additionally, weeks ago, OpenAI released a Codex plugin specifically designed for Claude Code users, allowing developers to directly call Codex for code review or task delegation within the Claude Code workflow.
Google is also active; Gemini CLI is currently completely free. According to The New Stack, Anthropic has recently been under pressure regarding computing supply. Not only did it remove Pro access to Claude Code, but it also previously cut off third-party client OpenClaw's access to Claude via subscription accounts. Platform stability issues and frequent outages have also provided opportunities for competitors.
