What each one is
Nginx Proxy Manager
Nginx Proxy Manager is a web interface that runs in a Docker container and lets you forward web addresses to services you host, such as apps on a home server. It can request free Let's Encrypt SSL certificates so traffic is encrypted, and it aims to work without deep knowledge of Nginx configuration files. The README says the goal is to keep the basic setup simple, with advanced options available but optional.
swag
swag reads special comments (annotations) you write above your Go API handlers and produces Swagger 2.0 documentation files, such as swagger.json and swagger.yaml, plus a docs.go file. The generated docs can be shown in Swagger UI so people can browse and test your API. It is used to keep API documentation close to the code it describes.

Strengths
Nginx Proxy Manager
- Browser-based admin interface that avoids hand-editing Nginx configuration
- Built-in free SSL through Let's Encrypt, or you can supply your own certificates
- Installs with a short Docker Compose file and is MIT licensed
swag
- Docs live next to the code, so they are easier to keep in sync
- Plugins are listed for many popular Go web frameworks
- Can be installed with go install or run through a Docker image
Not ideal for
Nginx Proxy Manager
- Large production deployments needing high-availability or enterprise traffic management, since the README focuses on simple home and small setups
- People who want full manual control over Nginx config files and prefer not to use a GUI
- Users who cannot run Docker or need a non-container install, as the README only documents the Docker image
- Users on armv7 hardware running version 2.14 or later, because armv7 support was dropped there
swag
- Projects that need OpenAPI 3.x output, since the README describes Swagger 2.0 generation
- Non-Go projects, since it parses Go source code
- Teams that prefer writing the API spec by hand as a separate file
Trade-offs
Nginx Proxy Manager
- Depends on Docker and on your router and DNS being set up correctly for outside access, which the README covers only briefly
- README does not describe scaling, backup procedures, or security hardening in detail
- The README says the admin interface can take a while to come up due to key generation
swag
- Output is Swagger 2.0 only according to the README, which is older than OpenAPI 3
- Documentation quality depends on how carefully annotations are written
- Latest release shown is a release candidate (v2.0.0-rc6), so it may not be the most stable choice
