OpenFlux

Flux is an open-source continuous delivery and GitOps solution for keeping Kubernetes clusters synchronized with configuration sources such as Git repositories and OCI artifacts. It is built on the GitOps Toolkit, a set of Kubernetes APIs and controllers for source management, Kustomize and Helm deployments, notifications, and image automation; its controllers reconcile custom resources to apply and update cluster state. Flux supports multiple Git repositories and multi-tenancy, and can deliver Helm releases and charts. The project is a graduated Cloud Native Computing Foundation project.

Flowsint is an open-source OSINT graph exploration tool for ethical investigation, cybersecurity analysis, and reconnaissance. It represents relationships between entities in a visual graph and uses automated enrichers for domains, IP addresses, ASNs, CIDRs, websites, social profiles, organizations, email addresses, phone numbers, cryptocurrency wallets, and other investigation data. Enrichers include DNS and reverse-DNS resolution, subdomain discovery, WHOIS, website crawling, link and text extraction, username searches through Maigret, breach checks, and cryptocurrency transaction and NFT lookups; an N8n connector supports workflow integration. The project is organized into a frontend application, a FastAPI server, core orchestration and vault utilities, Pydantic data types, and enricher modules. It uses PostgreSQL and Neo4j for data storage, Redis and Celery for task processing, and provides authentication, graph database integration, REST endpoints, and real-time event streaming. The application can be run locally or deployed on a server with Docker and Docker Compose, with data stored on the operator's machine. It is intended for lawful, ethical investigation and prohibits unauthorized intrusion, surveillance, harassment, doxxing, and other misuse.

fanqiang is a curated collection of internet-circumvention tools, tutorials, and related resources maintained in a GitHub repository. It curates guides and software for Windows, macOS, Linux, Android, iOS, routers, browsers, game consoles, and Apple TV, including instructions for configuring V2Ray, Shadowsocks, SSR, Clash, Tor Browser, and other proxy tools. The repository also includes bundled browser packages and guides for setting up self-hosted V2Ray or Shadowsocks servers, and states that its tool collection is periodically updated.

fx is an open-source coding-agent harness and command-line interface written in Zig by Vercel Labs. It is designed as a compact Unix-like alternative to a terminal IDE, with interactive and one-shot requests for inspecting and modifying repository code, running shell commands, and saving or resuming sessions. The agent supports skills, MCP tools, plugins, subagents, permission rules, and headless requests, and can be embedded natively or through WebAssembly. It is model-agnostic, supports local and cloud inference, is distributed under the Apache-2.0 license, and is marked experimental by its repository.

TrueForge is an open-source, vendor-neutral agent harness developed by TrueFoundry. It runs the agent execution loop, including model calls, MCP tool use, skills, sandboxed code and file execution, approvals, context management, and session state. Agents can use configured model providers, remote MCP servers, git-backed SKILL.md instruction packs, and on-demand sandboxes; context features include subagents, deferred tool loading, Code Mode, large-result offloading, and compaction. TrueForge exposes agents through a bundled chat UI, an HTTP API with a TypeScript SDK, and an embeddable UI SDK. It supports local mode with SQLite and hosted deployments using Postgres and Redis through Docker Compose or Helm; the repository warns that local mode is intended for personal use on localhost rather than production or internet-facing deployment.
