I have created a tool as OSS that can output a list of Lambdas filtered by region, runtime, version, and part of function name across regions with 1 command + interactive.
Overview
This is a one-command + interactive tool that allows you to output a list of Lambdas filtered by region, runtime, version, and a function name across regions.
With AWS CLI, you need to throw a command for each region, but with this tool, you can do flexible filtering with one command + interactive.
This tool will allow you can see the following.
- What Lambda functions exist in which regions
- Whether there are any functions that have reached EOL
- Whether there is a function in an unexpected region
- Whether a function exists based on a specific naming rule
Also this tool can support output results as a CSV file.
Source Code
Implemented in Go language.

How to use
lamver [-p <profile>] [-r <default region>] [-o <output file path>] [-k <keyword for function name>]
options
- -p, --profile: optional
- AWS profile name
- -r, --region: optional
- Default AWS region
- The region to output is selected interactively and does not need to be specified.
- -o, --output: optional
- Output file path for CSV format
- -k, --keyword: optional
- Keyword for function name filtering (case-insensitive)
Input flow
Enter lamver
❯ lamver
You can specify -k, --keyword option. This is a keyword for function name filtering (case-insensitive).
❯ lamver -k goto

Enter part of the function name
You can search function names in a case-insensitive.
Empty input will output all functions.
This phase is skipped if you specify -k option.
Filter a keyword of function names(case-insensitive): test-goto
The result will be output

INF 10 counts hit!
CSV output mode
By default, results are output as table format on the screen.
If you add -o option, then results can be output as a CSV file.
lamver -o ./result.csv
Finally.
It is a fairly simple tool, but I think you will find it surprisingly useful.
Please try it if you like!
