I've been working on some automation scripts for browser-based tasks like signing into applications, navigating dashboards, and extracting structured data. While my initial tests with tools like Selenium and Puppeteer went well, I've encountered issues when letting these jobs run for long periods. Sessions end up expiring, tabs forget their state, and the overall browser context becomes unreliable. I've also experimented with Hyperbrowser, which seemed to handle longer processes better, although it wasn't without its flaws. For those experienced in running browser automation in production environments, what strategies do you use to enhance stability? Is it primarily about implementing aggressive retries and health checks, or are there better architectural solutions or settings for maintaining long-lived sessions?

The term 'long-running browser automation' suggests some inherent instability. Switching to shorter automation tasks is usually a smoother route. If you can, break your jobs into smaller, quick tasks to reduce flakiness overall.
The problems with sessions expiring and tabs losing state are pretty typical in browser automation. Browsers aren't really designed for extended use like that. From what I’ve seen in production, it’s best to avoid trying to keep a browser running indefinitely. Instead, set up a system where you spin up new browser contexts every so often, like every 30 minutes or after a set number of actions. This way, you can treat the browsers as temporary, which helps a lot.
Consider using Anchor Browser's free tier. The issues you're facing may stem from garbage collection terminating idle sessions or cookies being dropped due to site defenses. Anchor offers persistent cloud browsers that don’t timeout, which might just solve your headaches.
Having solid session management is key. Retry logic is nice to have but only addresses the symptoms. Keeping too many tabs open can lead to memory issues since a lot of automation tools don’t clean up properly. I've been involved in building Notte, and we've found that managing sessions effectively can make a world of difference.
Absolutely! I've noticed keeping tabs limited really helps with performance too.
The session expiry issue can be a real pain. Managing browser automation at scale is tougher than many realize. We've learned to treat our browser instances as disposable. Run them for max 30-45 minutes, then restart with saved states. Running multiple instances in parallel also means you're covered if one crashes. Plus, keep an eye on memory usage; it can creep up unexpectedly, especially in Chromium.
Totally agree! We faced similar issues, and switching to better session management has helped us a ton.
