Scriv is a command-line tool for helping developers maintain useful changelogs. It manages a directory of changelog fragments. It aggregates them into entries in a CHANGELOG file.

code-forensics is a toolset for analysing codebases stored in a version control system. It leverages the repository logs, or version history data, to perform deep analyses with regards to complexity, logical coupling, authors coupling and to inspect the evolution in time of different parts of a software system with respect to metrics like code churn and number of revisions.

Code Maat is a command line tool used to mine and analyze data from version-control systems (VCS).

A terminal-based presentation tool with colors and effects.
You can also play a codio (pre-recorded code block) on a slide.

GitDuck is a video call tool built for developers that enables you to talk, share your code and do pair programming with ease.

Pyre is a performant type checker for Python compliant with PEP 484. Pyre can analyze codebases with millions of lines of code incrementally – providing instantaneous feedback to developers as they write code.

Pyre ships with Pysa, a security focused static analysis tool we've built on top of Pyre that reasons about data flows in Python applications.

Markdown editor to help organize research notes, with full Zettelkasten support.

Splitgraph is a data management, building and sharing tool inspired by Docker and Git that works on top of PostgreSQL and integrates seamlessly with anything that uses PostgreSQL.

Splitgraph allows the user to manipulate data images (snapshots of SQL tables at a given point in time) as if they were code repositories by versioning, pushing and pulling them.

Bandit is a tool designed to find common security issues in Python code. To do this Bandit processes each file, builds an AST from it, and runs appropriate plugins against the AST nodes. Once Bandit has finished scanning all the files it generates a report.

Bazel is an open-source build and test tool similar to Make, Maven, and Gradle. It uses a human-readable, high-level build language. Bazel supports projects in multiple languages and builds outputs for multiple platforms. Bazel supports large codebases across multiple repositories, and large numbers of users.

This app uses the API of other websites and gives you an RSS feed in return. Quick and simple.

A CLI tool to help working with Protocol Buffers.
Buf currently contains:

• A linter that enforces good API design choices and structure.
• A breaking change detector that enforces compatibility at the source code or wire level.
• A configurable file builder that produces Images, our extension of FileDescriptorSets.

Snowpack is a better build tool for modern web apps. Snowpack leverages ESM imports in your application to remove all unnecessary bundling work from your dev workflow. The end result is a build tool that starts up instantly and wastes no time rebuilding on every change. See changes reflected in the browser instantly.

Diagrams lets you draw the cloud system architecture in Python code.

It was born for prototyping a new system architecture without any design tools. You can also describe or visualize the existing system architecture as well.

Diagram as Code allows you to track the architecture diagram changes in any version control system.

Diagrams currently supports six major providers: AWS, Azure, GCP, Kubernetes, Alibaba Cloud and Oracle Cloud. It now also supports On-Premise nodes as well as Programming Languages and Frameworks.

Open Source cross-platform SQL Editor and Database Manager. Use Beekeeper Studio to query and manage your relational databases, like MySQL, Postgres, SQLite, and SQL Server. Available for Windows, Mac, and Linux.

semgrep is a tool for easily detecting and preventing bugs and anti-patterns in your codebase. It combines the convenience of grep with the correctness of syntactical and semantic search. Developers, DevOps engineers, and security engineers use semgrep to write code with confidence.

Basecamp is a web-based project management tool. Its primary features are to-do lists, milestone management, forum-like messaging, file sharing, and time tracking.

A CLI tool to easily save, access and organize daily notes, especially for daily standup meeting.

OpenVAS is a full-featured vulnerability scanner. Its capabilities include unauthenticated testing, authenticated testing, various high level and low level Internet and industrial protocols, performance tuning for large-scale scans and a powerful internal programming language to implement any type of vulnerability test.

Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle.

The idea is that during a test, a swarm of locusts will attack your website. The behavior of each locust (or test user if you will) is defined by you and the swarming process is monitored from a web UI in real-time. This will help you battle test and identify bottlenecks in your code before letting real users in.
