   A powerful little TUI framework 🏗

   

   Project mention: Introducing Dispositio! | dev.to | 2026-09-01

   But as some of my projects grew, I found simple text to be limiting. So, I got to cooking (in Go + BubbleTea) on a TUI project management system that would be commitable as simple Markdown text..

6. tidb

   5 36 40,624 9.9 Go

   TiDB is built for agentic workloads that grow unpredictably, with ACID guarantees and native support for transactions, analytics, and vector search. No data silos. No noisy neighbors. No infrastructure ceiling.

   

   Project mention: Go vet can't go: How PVS-Studio analyzes Go projects | dev.to | 2026-02-11

   A similar issue was also found in Tidb:

    Project mention: Docker Scout e Trivy segurança de imagens de contêiner na prática | dev.to | 2026-10-07

    Repositório do Trivy no GitHub

11. v2ray-core

    9 28 34,667 8.8 Go

    A platform for building proxies to bypass network restrictions. (by v2fly)

    VLESS Protocol Specification: https://github.com/v2fly/v2ray-core

12. cockroach

    10 119 32,543 10.0 Go

    CockroachDB — the cloud native, distributed SQL database designed for high availability, effortless scale, and control over data placement.

    

    Project mention: SQL vs. NoSQL — stop asking the wrong question | dev.to | 2026-09-06

    Also false. Postgres runs massive production workloads, and you'll hit product problems long before it's your bottleneck. And when you genuinely outgrow a single node, distributed SQL exists now — CockroachDB, Google Cloud Spanner, and Vitess all give you horizontal scale without giving up SQL.

13. k6

    11 37 31,837 9.8 Go

    A modern load testing tool, using Go and JavaScript

    

    Project mention: Docker Agent | news.ycombinator.com | 2026-10-07

    I agree! Comes with the territory of a compiled language I suppose?

    I haven't given this much thought (I also just started with golang last year) but I'm assuming the only real path here is to provide extension SDKs in Lua or other languages whose interpreters have been implemented in go.

    I think that's what grafana's k6 [1] does with a JS interpreter

14. nuclei

    Nuclei is a fast, customizable vulnerability scanner powered by the global security community and built on a simple YAML-based DSL, enabling collaboration to tackle trending vulnerabilities on the internet.

    ZAP is free. Nuclei checks for known exposures. StackHawk, Snyk API & Web and Checkmarx DAST are paid options. Give the scanner credentials and an API spec, or it will scan your login page and little else.
