I’ve been struggling with maintaining separate browser contexts when running automated workflows that require different accounts/sessions. Tried using multiple instances manually but keep hitting cookie clashes and data leaks between sessions. Seen people mention browser profiles and container tabs, but that gets messy at scale. How are others handling coordination between different authentication states and session data in complex automations? Specifically need something that prevents cross-contamination when running 5-10 parallel processes.
Latenode’s AI Teams solved this for us. Set up dedicated browser agents in the visual builder - each maintains its own cookies/local storage. They coordinate through the control plane without data mixing. We run 12 parallel checkout flows with separate accounts daily. Works with fingerprint randomization too.
I’ve used separate Firefox profiles with randomized user agent strings for this. Requires scripting to manage profile directories and ensure clean separation. The main challenge was preventing any localStorage bleed - ended up wrapping each session in its own Docker container. Curious if there’s a less resource-intensive approach.
We implemented a proxy rotation system that ties specific IP addresses to browser contexts. Each automation thread gets its own proxy+user agent combo. Still had some fingerprinting issues until we added canvas noise generation. Now considering moving to more managed solutions as maintenance overhead is high.
The optimal solution depends on your authentication requirements. For basic separation, Puppeteer’s browserContexts work but require careful orchestration. For sensitive data, isolated VMs or containerized browsers with ephemeral storage are safer. Remember to purge IndexedDB and Service Workers between sessions - that’s where most leaks happen unexpectedly.
try using chrome’s --user-data-dir flag with separate profile paths for each session. works better than cookies alone but needs disk space management. still get occasional cache clashes tho
