I'm currently working on automating dashboard logins and data extraction with Puppeteer and Selenium. While single runs are performing well, I've faced several issues when scaling up to multiple tabs or running jobs for longer durations. In these cases, my sessions often expire, I lose cookies, and tabs seem to lose their state, which sometimes logs me out in the middle of a process. I've experimented with different techniques like rotating proxies, custom user agents, and using persisted cookies. I've even shifted to using headless=new, which improved stability slightly, but it's still not reliable enough for production tasks. I'm trying to figure out what's causing this instability. Could it be related to session isolation, anti-automation measures, browser lifecycle issues, or something else? I would love to hear about any tools or methods you've used that can support long-lived, multi-account browser workflows without having to keep a constant eye on them. Any insights or experiences would be greatly appreciated!

Have you tried keeping the sessions active with periodic interactions? Simple actions like scrolling, clicking, or hitting an API endpoint can help. For larger multi-account operations, I switched from using raw Puppeteer to browserless.io, which made things so much easier. They handle session isolation, so you won't have to debug 'why did this break' as often. Don't forget to check if the site has short-lived cookies or silent re-authentication kicking in, as that can disrupt headless sessions too! You can monitor activitIes via the network tab in a regular browser to see what’s going on.
It sounds like your sessions are timing out because of the lifecycle limits in Puppeteer/Selenium. When using headless Chrome, idle tabs may be terminated after about 30 minutes, and this gets worse due to anti-bot defenses that can also lead to cookie loss. I've had good success with Anchor Browser, which allows for persistent cloud sessions. This keeps your state intact for hours or even days, enabling me to run over 50 tabs for lengthy workloads without issues. You might want to check out their API for handling multiple accounts effectively!
This aligns with Chrome's process management. Issues like idle tab eviction and memory pressure can worsen with more tabs open. If the browser decides to free up resources, any associated cookies and states are lost. That's a big part of the challenge you're facing.
You're right about cookies managing sessions and how they are shared across tabs of the same domain. To avoid the issues you're experiencing, consider using different browser instances or even different domains for your tests. Creating a separate sub-domain for each test might be a straightforward solution.
You might want to give Playwright a try. It does an excellent job of managing sessions through storage states, and many consider it the default choice for modern browser automation tasks.
Thanks for sharing that! It's good to know that the lifecycle limits are affecting things more than my automation setup. I’m really interested in how Anchor maintains session persistence without relying too much on cookies and keep-alives. I'll definitely explore their API for managing multi-account tasks.
