I work for a company that has some databases with content created by various freelancers since different domains require different experts with their respective area of expertise. One of these databases is moderately sized at 2000 entries with quite a number of interrelated columns. As is to be expected, it's a mess because no two people follow the same standards, and people can be sloppy sometimes in very technically nuanced ways that are hard to catch.
This is where Claude Code Web comes in. Together with the project lead, I created quite technical and nuanced instrucctions for Claude Code to analyze each and every entry in this database and perform a comprehensive fact check using various specialized subagents in parallel. We had already tested and refined the prompts so we knew it did a pretty good job in informing us of factual inaccuracies in the database content. Suddenly, I get 1000$ for free in Claude credits, so I spin up 30+ agents to work in parallel since this task is extremely parallelizable in nature. I'm mildly surprised it let me spin up that many agents. There was a toast message a couple of times that I apparently reached the concurrency limit, but it would just spin up the agents regardless.
I go for dinner, and once I come back I have burned through 500$ and fact-checked a decent chunk of my database and found a bunch of really nuanced factual inaccuracies. Rinse and repeat aaaaaaand it's gone. I burned through 1000$ of Claude Code Web credits in one evening.
But let's be real for a moment. Please don't burn tokens just because you can. Don't compete on token leaderboards and stuff like that. I did this specifically because
It is a very nuanced workflow that had been previously tested a lot and we knew from experience that it could reliably be highly parallelized since the individual database entriers are independent. It took me a few initial runs to adjust some minor things to the Claude Code Web environment but then it ran just as smoothly as in my terminal.
Facts for the database entries can be easily checked with web searches, but usually require checking various sources and aggregating a lot of information. Claude Code usually performs something between 10 and 30 web searches to verify all the factual claims in one entry, which is the bulk of the cost. Analyzing 100 entries takes about 2000 web searches plus a bunch of additional work.
It actually provides significant value because the database that contains client-facing information now can be turned into something more professional and detailed with much less effort because our domain expert can just evaluate Claude's detailed reports on issues and double check the various sources and links it has provided. The actual value are literally hundreds of hours of work saved.
So, the question is: will I keep using Claude Code Web with my Claude Max subscription going forward? Yes, but only occasionally for now. I still prefer the terminal for more complex things and the fact that it spins up a new environment every time comes with some drawbacks. But I think it is quite decent for long-running established or simple workflows that you can just kick off and then forget about. For these it can be nice to just kick them off and be able to close my laptop. The only other application I honestly see is coding from my phone, which I don't expect I will be doing a lot but I think occasionally it will be helpful.
TL;DR: I gave Claude Code Web a highly parallelizable fact-checking task that requires a lot of web searches from different sources. Used the 1000$ free credits to do in an evening what would have required hundreds of hours of human work.
