# How ChatGPT Codex Has Caught Up With Claude Code In Website Visits > Source: > Published: 2026-08-09 07:48:54+00:00 Claude Code had been the first breakout coding product in the AI space, but it now has some serious competition. New data from Similarweb tracking daily website visits to Claude.ai/Code and ChatGPT.com/Codex through July and into August shows a race that has tightened considerably over the past month, with OpenAI’s coding agent closing a gap that once looked comfortable for Anthropic. At the start of the tracked period in early July, the difference between the two products was stark. Claude Code was pulling in over 200,000 daily visits while ChatGPT Codex sat under 100,000, barely half of its rival’s traffic. For the first ten days of the month, Claude Code held a commanding lead, climbing as high as 290,000 visits while Codex crawled upward in the 100,000 to 190,000 range. Anthropic’s tool had built this lead on the back of genuine developer enthusiasm, helped along by moments like Boris Cherny [revealing that as much as 80 percent](https://officechai.com/ai/80-of-claude-codes-code-is-written-by-claude-code-anthropic-lead-engineer/) of Claude Code’s own codebase was being written by Claude Code itself, a statistic that made the rounds across developer circles and gave the product a kind of self-referential credibility few tools manage. The shift begins around July 13 and 14, when Codex’s traffic line goes almost vertical. It jumps from roughly 145,000 to over 300,000 visits in a matter of days, briefly overtaking Claude Code entirely. This is the first point in the chart where the orange line sits above the navy one, and it marks a genuine inflection rather than a one-day spike. From that point on, the two products spend most of the rest of July trading positions rather than one simply dominating the other. What follows is a month of volatility on both sides. Claude Code dips to around 220,000 visits by July 19, then rockets back up to nearly 300,000 by July 21, its highest point in the entire dataset. Codex, meanwhile, has its worst stretch around July 22, crashing to under 190,000 visits before clawing back to the low 260,000s within days. Neither product manages a clean, sustained lead for more than a few days at a stretch during this window, which suggests that whatever is driving these swings, whether product updates, viral moments, or simple usage cycles among developers, is affecting both platforms on similar timelines. By the last week of July, the two lines are running almost parallel. Claude Code climbs back to around 290,000 visits between July 27 and 29, while Codex tracks close behind in the 260,000 to 280,000 band. This is the tightest sustained convergence in the entire chart, and it is a far cry from the double-the-traffic advantage Claude Code held just three weeks earlier. Both products then decline together into the first days of August, with Claude Code settling around 197,000 visits and Codex just behind at 213,000 by August 1, a reversal of their positions from a month prior. The trend lines up with what has been a period of aggressive shipping on OpenAI’s side. The company has been pushing Codex hard as more than a coding sidekick, positioning it as part of a broader agent platform, and pouring resources into the infrastructure behind it, including its recently announced [custom AI chip built with Broadcom](https://officechai.com/ai/openai-has-designed-and-built-its-first-ai-chip-named-jalapeno-in-partnership-with-broadcom/), purpose-built around workloads like ChatGPT and Codex. Anthropic, for its part, has not been standing still either. Claude Code has reportedly reached [4% of all public GitHub commits](https://officechai.com/ai/4-of-github-commits-are-now-made-by-claude-code-semianalysis-report/), and the company recently expanded the underlying idea behind the product into Cowork, a non-coding version of the same agentic workflow. What the Similarweb numbers ultimately capture is a market that has stopped being a one-horse race. Claude Code got there first and built a passionate, vocal user base that treated the tool almost like a cult product among developers. But Codex has spent the better part of the summer proving that OpenAI’s distribution advantage, its existing base of over 100 million weekly ChatGPT users, and its willingness to ship updates at a rapid clip can translate into real traffic gains against a rival that had a considerable head start. Whether this convergence holds through August or one product pulls ahead again will depend on factors the traffic data alone cannot explain, things like model quality, pricing changes, and which company ships the next feature that developers actually want to talk about. For now, though, the numbers make one thing clear: the gap that once separated Claude Code from everyone else in agentic coding has narrowed considerably, and ChatGPT Codex is no longer playing catch-up from a distance.
