    Crystal has an active and growing community. It also boasts a rich ecosystem with libraries and tools, making it easier for developers to find resources and support.

Possible disadvantages of Crystal (programming language)

  • Maturity
    Crystal is still a relatively young language compared to more established languages like Python or Java. This can mean fewer resources, libraries, and tools, as well as potential instability in certain areas.
  • Compilation Time
    Crystal's compilation times can be slower compared to interpreted languages, particularly for larger codebases. This can impact development workflows and iteration speed.
  • Binary Size
    Compiled Crystal programs tend to generate larger binary sizes compared to other compiled languages like Go or Rust. This can be a consideration for resource-constrained environments.
  • Platform Support
    Being less mature, Crystal may have fewer options for platform-specific optimizations and integrations, which could limit its use in certain specialized applications.
  • Tooling
    Although the situation is improving, Crystal's tooling ecosystem is not as mature as those of older languages. This can affect the availability and quality of IDE support, debugging tools, and other development aids.

Possible disadvantages of WireGuard

  • Limited Features
    WireGuard primarily focuses on being a secure VPN protocol and lacks some advanced features found in other protocols.
  • Still Evolving
    As a relatively new technology, WireGuard may still undergo significant changes and improvements, which could impact stability and support.
  • Static IP Assignment
    WireGuard assigns static IP addresses to each peer, which can be less flexible compared to dynamic IP allocation in other VPN solutions.

    Some legacy infrastructures and older systems may not support WireGuard natively, creating challenges for widespread deployment.
  • No Built-in Authentication
    WireGuard itself does not include built-in authentication mechanisms, relying solely on public key cryptography for peer identification.
  • No Built-in Traffic Obfuscation
    WireGuard lacks built-in mechanisms for traffic obfuscation, making it easier for restrictive networks to detect and block WireGuard traffic.

Best Top 20 OpenVPN Alternatives (Pros and Cons)
Wireguard is a VPN alternative that is under development. Yet it is faster and carefully designed when compared to other similar products.
6 Types of VPN Protocols, Compared: Which is the Best to Use?
In essence, every VPN has to strengthen WireGuardโ€™s wobbly privacy to benefit from its speed and security. Thatโ€™s why we recommend using WireGuard-based protocols only if they come from reputable VPN providers. NordVPN, for example, fixes WireGuardโ€™s privacy issues with the so-called โ€œdouble NAT systemโ€ (network address translation). This allows them to establish secure...

OpenVPN vs WireGuard: Which protocol is best?
WireGuard was not designed to obfuscate user traffic to this degree, and only supports UDP. This means that a simple, standalone WireGuard connection is easy to detect. However, as WireGuard is so extensible, most VPN providers have added their own obfuscation methods on top. The efficacy of these varies, but weโ€™ve seen services with WireGuard support that even work in...

Crystal (programming language) mentions (123)

  • Ruby for Good
    Which can include type assertions but also a lot more. The agents seem to do well with this. I've also had good results using agents to write Crystal https://crystal-lang.org/ which is Ruby-like but does have the static types and produces blazing fast static binaries. Might be a sweet spot for coding agents if you're building some backend services. But I'd still pick Ruby on Rails for a new full stack project. - Source: Hacker News / about 2 months ago

    Sounds a lot like Crystal, which is also similar to Ruby and features a green fiber runtime: https://crystal-lang.org/#concurrency. - Source: Hacker News / 2 months ago
  • A Grand Vision for Rust
    > 1. Go with a better type system. A compiled language, that has sum types, no-nil, and generics. I was looking for something like that and eventually found Crystal (https://crystal-lang.org) as a closest match: LLVM compiled, strong static typing with explicit nulls and very good type inference, stackfull coroutines, channels etc. - Source: Hacker News / 4 months ago

  • Remote access from work/corporate network
    Wireguard. Wireguard uses UDP only and runs TCP sockets over UDP. Source: about 3 years ago
  • Central reverse-proxy ssh access?
    Look at Wireguard. I know you don't want Yet Another VPN running alongside your IPSec, but it's less VPN and more encrypted point-to-point UDP. You can set it up on any port you wish, including common ports that might be open on an outbound smart firewall not doing deep packet inspection. That way, it can stay out of the way of your existing IPSec deployment. Source: about 3 years ago

    Both products are based off Wireguard which is available for all new linux distributions. https://wireguard.com . I'm not saying OP's solution is wrong, just curious what the advantages are. Other than potentially simpler client setup, what are the advantages of paying for tailscale. With the opensource tailscale, I'm not sure if you get access to an api you can use to look up the hosts.
