I've been creating automation scripts for browser tasks like logging into applications, navigating dashboards, and extracting data. While my early tests with tools like Selenium and Puppeteer went well, I encountered issues when I let the jobs run for a longer time. I faced problems like session expirations, loss of tab states, and unreliable browser context. Out of curiosity, I experimented with Hyperbrowser and found it managed longer executions better than the others, though it still wasn't perfect. For those experienced in running browser automation in production, what best practices do you have to ensure stability over time? Is it more about implementing aggressive retries and health checks, or are there architectural decisions or runtime configurations that significantly help with maintaining long-lived sessions?

Managing browser automation, especially at scale, can be quite tricky. At our team, we treat browser instances as temporary—running them for about 30-45 minutes max, then killing and restarting while saving the necessary state. We also find it beneficial to run multiple instances in parallel so that if one dies, we still have others operational. Don’t underestimate memory leaks in Chromium; keeping an eye on RAM usage is vital—it often climbs higher than you'd expect!
Proper session management is crucial! Instead of just layering retry logic on top, focus on how sessions are managed at the browser level. Make sure you're not overflowing the browser with too many open tabs, as this can cause memory leaks, which can spiral out of control over extended periods.
Exactly! I've noticed that when we keep too many tabs active, it leads to significant slowdowns. Managing how many instances are running at one time really does make a difference.
Give Anchor Browser's free tier a try. It might solve the problems you're facing, particularly with garbage collection terminating idle sessions and site defenses breaking cookies. Their cloud browsers offer persistent remote contexts that won't time out, which could be a game changer for your automation needs.
It's common for browser automation to struggle in prolonged scenarios. The key is to not rely on keeping the same browser session alive indefinitely. Instead, set up aggressive session recycling—this means creating new browser contexts every so often or after a certain number of actions. Think of the browser as disposable. The better performance of tools like Hyperbrowser likely comes from their automated session management features that handle these issues more seamlessly. Relying solely on retry logic will only get you so far; it's essential to design your automation with the understanding that your browser might crash at any moment and minimize the impacts.
Ah, 'long running browser automation' is where the challenge lies. These setups tend to be pretty flaky by nature. A straightforward workaround is to switch to a short-running automation model instead. It'll probably save you a lot of headache down the line!
Good point! We've gotten better results by setting tight controls on memory usage and ensuring we restart processes regularly. It really helps with stability.
