The aws cli does not provide a live tail -f option.

Those other tools mentioned above do provide a tailing feature, however, I tried all these tools, awslogs, cwtail and found them frustrating. They were slow to download events, often unreliable and not helpful in displaying JSON log data and were primitive with query options.

I wanted an extremely fast, simple log viewer that would allow me to instantly and easily see application errors and status. The CloudWatch logs viewer is slow and CloudWatch Insights can take > 1m for some pretty basic queries.

So I created SenseLogs, a free AWS CloudWatch Logs viewer that runs entirely in your browser. There is no server-side services required. SenseLogs transparently downloads log data and stores events in your browser application cache for immediate viewing, smooth infinite scrolling and full text queries. SenseLogs has live tail with infinite back scrolling. See https://github.com/sensedeep/senselogs/blob/master/README.md for details.
