Twitch and YouTube Live, replaced by infrastructure you control: Owncast is a self-hosted live streaming and chat server. Point OBS, Streamlabs, or any RTMP-capable broadcaster at the server's ingest port, and Owncast transcodes the feed with FFmpeg into HLS with multiple quality variants, playing it in a built-in web page with a real-time chat beside it. Chat supports anonymous participation, custom emotes, and moderation tools - message removal, user bans and suspensions - with optional authentication via IndieAuth or a Fediverse account. ActivityPub integration puts the stream on the Fediverse: viewers on Mastodon and compatible services can follow a channel and get notified the moment it goes live. Video delivery can come straight off the server or offload HLS segments to S3-compatible object storage so a modest VPS handles thousands of concurrent viewers while only managing ingest and chat. The backend is a single Go binary with a React frontend - no accounts platform, no database server, no dependency stack - and the player embeds in any website. MIT-licensed, with roughly 9k GitHub stars, zero platform fees, and no algorithm or takedown policy between you and your audience.

RAGFlow has established itself as one of the most widely adopted open-source RAG engines available, powering production AI systems that demand traceable, hallucination-free answers from complex enterprise data. The platform processes PDF, DOCX, Excel, and PPT files through vision-based deep document understanding with layout analysis and OCR, extracting structured knowledge from tables, charts, and images that simpler parsers miss entirely. RAGFlow's hybrid retrieval pipeline combines vector search with BM25 keyword matching and multi-stage reranking across configurable document stores including Elasticsearch, InfiniFlow's Infinity engine, OpenSearch, and OceanBase. Developers connect any combination of LLM providers — OpenAI, DeepSeek, Anthropic Claude, Google Gemini, and locally-hosted models via Ollama — through a unified configuration layer. The visual agent workflow system enables multi-step reasoning chains with persistent memory, tool calling, and pre-built templates for common enterprise scenarios. RAGFlow synchronizes data from Confluence, S3, Notion, and Google Drive, and delivers answers through chat integrations with Feishu, Discord, Telegram, and Line. The Python SDK and RESTful API on port 9380 provide programmatic access to knowledge base management, document parsing, and conversational retrieval. The full stack deploys via Docker Compose with MySQL for metadata, Redis for task orchestration, and MinIO for object storage.

With over 52,000 GitHub stars and its role as the foundation of every Kubernetes cluster worldwide, etcd is the distributed key-value store that handles the most critical data in modern infrastructure — cluster state, configuration, service discovery, and distributed coordination. Built in Go and graduated from the CNCF, etcd uses the Raft consensus algorithm to maintain a strongly-consistent, highly-available replicated log across a cluster of machines, gracefully handling leader elections during network partitions and tolerating machine failure including the leader node. The gRPC API provides atomic key-value operations including put, get, delete, and transactions with multi-key compare-and-swap semantics, enabling distributed locking, leader election, and configuration management without external coordination. Watch operations stream real-time change notifications for specific keys or key ranges, powering reactive architectures that respond immediately to configuration updates. Version 3.7 introduces RangeStream for streaming large result sets in chunks, keys-only range requests for faster metadata queries, and bootstraps entirely from v3store after eliminating the legacy v2 store dependency. Automatic TLS encryption with optional client certificate authentication secures all cluster communication, while role-based access control restricts key access per user. The embedded bbolt B+ tree storage engine provides consistent reads and writes with configurable compaction policies. Benchmarked at 10,000 writes per second per instance with linearizable reads, etcd supports clusters of 3, 5, or 7 members for fault tolerance.

With over 32,000 GitHub stars and adoption by DoorDash, Netflix, and Bose, CockroachDB is the distributed SQL database designed to survive disk failures, machine outages, rack losses, and entire datacenter failures while maintaining strongly-consistent ACID transactions with serializable isolation by default. The architecture layers SQL on a transactional key-value store using the Raft consensus protocol for synchronous replication, automatically splitting data into ranges that distribute and rebalance without manual sharding. PostgreSQL wire protocol compatibility means existing drivers, ORMs, and tools including psycopg2, pgx, ActiveRecord, Django ORM, GORM, Hibernate, and Prisma work without modification. Multi-region capabilities include configurable survival goals at region or zone level, table-level locality settings for pinning data to specific geographies for GDPR compliance, and follower reads for low-latency global queries. The built-in DB Console provides cluster overview dashboards, node maps showing geographical distribution, SQL activity pages tracking statement fingerprints, transaction latency percentiles, session details, and real-time metrics for queries per second, storage capacity, and replication status. Change data capture streams row-level changes to Apache Kafka, Google Cloud Pub/Sub, or webhook endpoints for event-driven architectures. Online schema changes execute ALTER TABLE without locking or downtime, and distributed backup supports full and incremental snapshots to S3, GCS, Azure Blob, and NFS. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. CockroachDB Software License (source-available).

Autonomous red team execution without manual script coordination is what PentaGI delivers through a multi-agent penetration testing platform engineered for automated security assessments. Security engineers configure testing scopes, target IP ranges, domain lists, and rules of engagement through an interactive web console with real-time execution graphs. Autonomous agent personas break down high-level assessment goals into discrete tactical phases, orchestrating network port discovery, service banner fingerprinting, web application crawling, and CVE verification. Specialized agents query integrated Graphiti knowledge graphs and local vulnerability repositories to synthesize attack paths, validate exploitability, and confirm finding veracity before issuing alerts. Operators monitor live agent terminal streams, inspect sandboxed tool executions, and adjust active LLM provider routes across OpenAI, Anthropic, or local Ollama endpoints. The template editor allows red teams to compose reusable testing playbooks with customizable security prompt chains, safety constraints, and automated remediation reporting.

Authelia is the leading open-source SSO and multi-factor authentication server for self-hosted infrastructure. The Go backend compiles to a single binary or Docker container image, serving a TypeScript React web portal that handles first-factor username and password login, second-factor authentication via TOTP, WebAuthn FIDO2 security keys, passwordless passkeys, and Duo mobile push notifications, and an OpenID Connect 1.0 and OAuth 2.0 identity provider with device code flow, JWE encrypted ID tokens, custom claims policies, and network-scoped authorization criteria. The forward authentication model integrates with Nginx auth_request, Traefik ForwardAuth, HAProxy, Caddy, Envoy, SWAG, and Skipper reverse proxies, injecting Remote-User, Remote-Groups, and Remote-Email headers into authorized requests. Granular access control rules match subject, groups, request URI, HTTP method, and network to enforce one-factor and two-factor policies per route. The user backend supports LDAP with attribute mapping, connection pooling, and bind mode, or YAML file-based authentication with Argon2id hashed passwords. Session state stores in Redis for high availability across clustered deployments, while persistent data lives in SQLite, MySQL and MariaDB, or PostgreSQL. Brute force protection locks accounts after configurable failed attempts, and email-based identity verification handles password resets and device registration. Dark, light, and OLED themes with i18n localization customize the portal appearance. On RepoCloud, deploy Authelia on a dedicated VPS with Docker, root SSH access, and complete control over your authentication infrastructure, all under the Apache-2.0 license.

Service businesses get a booking page without per-booking commissions or monthly SaaS fees from Easy!Appointments, the self-hosted appointment scheduler. Customers pick a service, provider, and open time slot from a clean web form; the system enforces working plans, breaks, and booking rules you define per provider, then confirms by email to both sides. The structure fits real service organizations: multiple providers with individual schedules, multiple service types with their own durations and prices, and admin/secretary roles for front-desk management. Two-way Google Calendar synchronization keeps each provider's external calendar authoritative - book in Easy!Appointments and it appears in Google Calendar, block time in Google and the slot disappears from the booking form. Version 1.6 adds SMS notifications and payment support, and a REST API opens the scheduling data to custom integrations. Built on PHP (CodeIgniter) with MySQL, it installs in a single folder and can share a database with your existing site; a WordPress plugin embeds the booking form directly in pages or posts. The interface ships in dozens of languages with time-zone handling throughout. GPL-3.0 licensed and free for commercial use - a helpdesk, clinic, salon, or consultancy runs its whole booking workflow on its own server.

Ory Hydra is an OpenID Certified OAuth 2.0 and OpenID Connect provider that plugs into any existing user database or authentication system through a headless consent and login bridge, letting you own your authorization infrastructure without rebuilding identity management from scratch. The Go binary ships at under 15MB with zero system dependencies and exposes two distinct API surfaces: a public endpoint on port 4444 handling authorization code flows, token exchanges, PKCE challenges, device authorization grants per RFC 8628, and OpenID Connect discovery, plus an admin endpoint on port 4445 managing client registration, token introspection, consent session lifecycle, and JWKS rotation. Access tokens can be issued as opaque reference tokens or signed JWTs for stateless validation at resource servers, while refresh token rotation, token revocation per RFC 7009, and pairwise subject identifiers provide granular security controls. Persistent storage spans PostgreSQL, MySQL, and CockroachDB with automatic schema migrations, and the architecture supports horizontal scaling behind load balancers with shared database state. Dynamic client registration per RFC 7591 enables automated provisioning, and the OAuth 2.0 Threat Model security considerations are implemented as default behaviors rather than optional add-ons. Trusted by OpenAI and other internet-scale platforms.

libSQL bridges the gap between SQLite's legendary simplicity and the server-accessible database model developers expect from PostgreSQL and MySQL, adding network access, replication, and vector search while maintaining full file format and API compatibility. The sqld (SQL daemon) component transforms SQLite into a network-accessible database server accepting queries via HTTP with JSON payloads, WebSocket connections, and a Hrana protocol optimized for low-latency edge access. Client libraries for TypeScript, JavaScript, Rust, Go, and Python connect to sqld identically to any traditional client-server database, while the LD_PRELOAD compatibility layer enables switching existing SQLite applications from local to remote mode without code changes. Embedded replicas synchronize a local SQLite copy inside your application process with the primary server, delivering sub-millisecond read latency while maintaining consistency through streaming replication. Bottomless replication continuously backs up database state to S3-compatible object storage with generation-based snapshots and WAL page shipping, providing point-in-time recovery without manual backup scheduling. Native vector search enables semantic similarity queries directly within SQL using cosine distance functions, eliminating the need for external vector database infrastructure. Read replica support distributes query load across multiple sqld instances, and integration with mvSQLite adds multi-version concurrency for high-availability deployments.
