Born at Brazilian media giant Globo.com, Thumbor answers imaging CDNs like Imgix and Cloudinary with an HTTP service where every image variant is just a URL. Ask for /300x200/smart/your-image.jpg and Thumbor fetches the original, crops and resizes on demand, and caches the result - one source file, unlimited renditions, no batch pre-generation pipeline. The "smart" in the URL is the signature feature: OpenCV-based face detection finds people in the frame and crops around them (no more thumbnails with severed heads), and when no faces exist, feature detection finds visually important corners and computes a weighted center of mass as the focal point. Beyond cropping, a chainable filter pipeline handles brightness, contrast, grayscale, blur, red-eye removal, rounded corners, rotation, watermarks, and format conversion with quality control - applied in order via URL segments. All common image formats work out of the box, and every layer is pluggable: loaders (HTTP, local, S3), storages and result storages (local, S3, Ceph, and community backends), engines, optimizers, filters, and even custom detectors, with the awesome-thumbor list cataloging the ecosystem. URL signing prevents abuse of your processing capacity. Integrations exist for Django, Rails, Node, WordPress, and most frameworks. MIT-licensed, battle- tested for over a decade.

BitRouter is a context-aware LLM router that learns which model delivers the cheapest successful outcome per workflow step, cutting agent costs by up to 80% while maintaining 96% quality versus all-frontier baselines. Point any agent runtime at http://localhost:4356 with a one-line OPENAI_BASE_URL change and BitRouter routes to OpenAI, Anthropic, Google, Groq, DeepSeek, Mistral, Moonshot, MiniMax, Nvidia, and any OpenAI-compatible endpoint simultaneously, normalizing authentication, streaming, and cross-protocol translation between wire formats. The act-observe-evaluate-learn loop traces every hop with cost, tokens, and latency attribution, scores each decision against a versioned policy-lock.yaml, then tightens routes automatically with no LLM judge in the path. Native MCP gateway auto-discovers tools from connected servers and makes them routable and governed alongside model calls. Agent Client Protocol integration enables the TUI to manage Claude Code, Codex, OpenCode, OpenClaw, Gemini, and Copilot sessions in real time with inline tool-call approval and live streaming. Built-in guardrails inspect, redact, or block risky content before requests leave your network. Virtual keys scope API access per agent or user without exposing upstream credentials. Per-agent spend caps and loop guards contain runaway cost automatically. Multi-account failover reroutes mid-run so rate limits never re-pay completed work. Ships as a single Rust binary via npm or Cargo. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

AWX transforms Ansible from a command-line tool into a centralized automation hub with a web UI, REST API, and distributed task engine for managing playbooks, inventories, and credentials at enterprise scale. The React-based dashboard provides real-time visibility into job status, inventory health, and execution history while Django REST Framework powers programmatic control over every automation resource. Job templates combine Ansible playbooks, inventories, and credentials into reusable units that chain together in workflow templates using directed acyclic graph orchestration with conditional branching on success, failure, or always-run logic and configurable convergence gates. The RBAC system built on django-ansible-base provides granular permission control over organizations, teams, projects, inventories, and credentials at object-level granularity. Dynamic inventory sources pull host data from AWS EC2, Google Cloud, Microsoft Azure, VMware vCenter, and Red Hat Satellite, while credential management securely stores SSH keys, cloud tokens, and vault passwords with HashiCorp Vault and CyberArk integration for external secret retrieval. Notifications deliver alerts via Slack, email, PagerDuty, Mattermost, IRC, and webhooks, while activity streams log every action for compliance auditing. The Receptor mesh network distributes job execution across isolated container-based execution environments with capacity-aware scheduling and hop-node routing for network-segmented infrastructures. Upstream of Red Hat Ansible Automation Platform. Deploys via Docker Compose with PostgreSQL and Redis or via the AWX Operator on Kubernetes. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

CoreObs delivers a unified self-hosted dashboard that replaces the typical combination of Uptime Kuma, Homer, and separate monitoring tools with a single interface for managing your entire server infrastructure. The Next.js frontend with shadcn components provides a modern dark-themed UI displaying server hardware metrics collected by a lightweight Go agent that leverages Glances for hardware abstraction — streaming real-time per-core CPU load, RAM utilization, NVIDIA GPU statistics, disk usage, system uptime, and load averages via WebSocket connections. The application registry tracks all self-hosted services with configurable uptime monitoring, availability history charts, and instant notifications through Discord, Telegram, Pushover, and email when services go down or recover. Quick-access links provide one-click navigation to each application's management panel directly from the dashboard. The network visualization module built on React Flow enables creating visual topology maps of your infrastructure with drag-and-drop nodes representing servers, switches, and services connected by labeled edges. Server data can be organized with tags, copied between entries, and monitored with configurable pagination and compact view modes. Deploy via Docker Compose with three containers — the Next.js web interface, the Go monitoring agent, and PostgreSQL 17 for persistent storage. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

A status page and uptime monitor in one Go binary: Statping-ng - the actively maintained fork of Statping - replaces the UptimeRobot-plus-Statuspage combo with a ~20 MB Docker image using under 50 MB of RAM. It checks services over HTTP, TCP, UDP, ICMP ping, and gRPC health checks on configurable intervals, with per-service timeouts, expected status codes, POST requests with custom JSON bodies, SSL verification, and failure thresholds before alerting. The public status page is the differentiator against plain monitors: visitors see live status, uptime percentages, and latency charts grouped into service categories, with incident announcements and scheduled-maintenance messages you publish from the dashboard - and Sass-based custom styling matches the page to your brand rather than a vendor template. When something fails, notifiers fire immediately: Slack, Discord, Telegram, SMTP email, PagerDuty, Twilio SMS, Pushover, and custom webhooks, each testable before saving. Because notifiers are single Go files, the plugin system makes new channels straightforward. A RESTful API manages services and reads uptime data programmatically, and the free Statping mobile app connects to your server via QR code for on-the-go monitoring. Data persists to SQLite, MySQL, or PostgreSQL. Point it at internal services too - anything the container can reach is monitorable.

Ralph tracks thousands of assets across data centers and back offices through a unified CMDB, DCIM, and asset management platform, providing the same capabilities as ServiceNow, Device42, and Sunbird dcTrack without per-asset licensing fees. Used by Allegro in production and backed by over 2,500 GitHub stars, it is built on Python 3 with Django and Django REST Framework. Interactive data center floor plans support drag-and-drop rack placement, front and rear rack views showing U-level asset positioning, power consumption tracking per PDU, and ethernet and fiber connection mapping. The back office module manages laptops, desktops, printers, mobile phones, and accessories with user assignment tracking, warehouse inventory, stock-taking audits, and automated loan workflows. IP address management handles network environments with DHCP and DNS integration alongside network topology visualization. Software license tracking monitors per-user and per-core allocations with usage calculations, compliance reporting, and expiration alerts, while vendor support contracts track SLA agreements and warranty renewal dates. The transitions system automates asset lifecycle processes through configurable workflows that trigger HTTP webhooks, custom Python scripts, email notifications, and Puppet and Ansible configuration management integration. Custom fields extend the data model with text, numbers, dates, choices, and URLs per asset type, accessible via the REST API. Multi-tenant architecture organizes assets by regions, data centers, service environments, and business units. Deploy via Docker with the allegro/ralph image alongside MySQL and Redis. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

Usulnet packs container management, Trivy security scanning, Nginx reverse proxy, scheduled backups, WireGuard VPN, firewall rules, and multi-node orchestration into a single 70MB Go binary with zero external runtime dependencies. Every module ships in one download with no paid tiers, no telemetry, and no edition gating. Container lifecycle management covers creation, start, stop, restart, pause, kill, and removal with bulk operations, real-time resource statistics, filesystem browsing, and settings editing. Trivy integration scans images and running containers for CVEs with severity scoring, generates SBOMs, and validates CIS benchmarks. The multi-node architecture supports standalone, master, or agent modes where agents connect over NATS JetStream with mTLS encryption, enabling remote Docker host management from a central dashboard. Reverse proxy configuration handles Nginx with automatic Let's Encrypt certificates, TCP/UDP stream proxying, access lists, and dead host detection. Backup operations capture container volumes and Compose stacks on configurable schedules with retention policies and full restore capabilities. A built-in application catalog provides 60+ one-click templates for common services. JWT license validation uses an RSA-4096 public key embedded in the binary, requiring no call-home and working entirely offline. For teams tired of maintaining separate tools for each infrastructure concern, Usulnet collapses the entire stack into a single point of management with Docker Compose deployment alongside PostgreSQL, Redis, and NATS.

A minimal Ubuntu 24.04 LTS virtual private server — no pre-installed applications, no opinionated configuration, just the operating system and root access. Start from a clean slate and install exactly what you need: web servers, databases, development toolchains, CI runners, monitoring stacks, VPN endpoints, game servers, or anything else that runs on Linux. The server ships with apt package management, systemd service supervision, and standard networking configured out of the box, giving you access to over 36,000 packages in the Universe repository alone. Connect via SSH with the key you select during deployment; a dedicated IPv4 address is included with every server at no extra charge. A browser-based serial console in the RepoCloud dashboard provides emergency access without an SSH client. Snapshots let you capture the server state before risky changes and roll back with one click. Resize CPU and RAM on demand without reinstalling. Canonical's standard security maintenance covers this LTS release through May 2029 — five years of patches for the Main repository. Ubuntu Pro extends that to ten years with additional Universe coverage, kernel livepatching, and compliance tooling, available free for up to five machines.
