Fast, native terminal emulator

GPU-accelerated terminal emulator written in Zig by Mitchell Hashimoto (HashiCorp co-founder). Native UI rendering on macOS and Linux. Supports ligatures, true color, Kitty graphics protocol, and splits/tabs. Configurable via a simple key-value file with sensible defaults. Open-source with 20K+ GitHub stars and a focus on correctness, speed, and minimal resource usage. Growing as a modern alternative to iTerm2, Alacritty, and WezTerm.

Anthropic's agentic coding CLI

Anthropic's agentic CLI coding tool that delegates complex tasks to Claude directly from the terminal. Understands entire codebases via automatic context gathering, edits multiple files, runs shell commands, and manages Git workflows autonomously. Supports CLAUDE.md for persistent project instructions, integrates with VS Code and JetBrains, and uses Claude Opus/Sonnet with extended thinking for complex architectural decisions. Built for terminal-first developers.

Container-native local AI model serving with Podman

RamaLama is an open-source tool that containerizes AI model inference using Podman or Docker, eliminating host system configuration complexity. It auto-detects GPUs (NVIDIA, AMD, Intel, Apple Silicon), pulls models from HuggingFace, Ollama, and OCI registries, and runs them in isolated rootless containers with read-only mounts and network isolation. Developed under the Containers project (Red Hat ecosystem), it brings familiar container workflows to local LLM serving.

Fast and lightweight Docker Desktop alternative for macOS

OrbStack is a macOS application that replaces Docker Desktop with lightweight container and Linux VM management. Its docs emphasize fast starts, lower CPU and memory overhead, and native macOS integration with menu bar controls, file sharing, and network access to containers by name, with exact gains depending on workload. Supports Docker, Kubernetes, and full Linux VMs.

Heroku-like PaaS built on Kubernetes with YC backing

Porter is a YC-backed platform-as-a-service that provides a Heroku-like deployment experience on top of Kubernetes. It abstracts away cluster management while giving teams full access to underlying infrastructure when needed. Supports deploying from Git repos, Docker images, or Helm charts with automatic HTTPS, scaling, and preview environments. Runs on AWS, GCP, or Azure.

Ephemeral preview environments for every pull request

Bunnyshell automates the creation of full-stack ephemeral environments that spin up for every pull request and tear down when merged. Each environment is a complete replica of the application stack including databases, APIs, and frontend services. Integrates with GitHub, GitLab, and Bitbucket to provide shareable preview URLs for testing, QA, and stakeholder review.

Open-source microVMs for secure serverless and AI agent sandboxing

Firecracker is an open-source virtual machine monitor that creates lightweight microVMs with sub-150ms cold starts, originally built by AWS for Lambda and Fargate. With 28,000+ GitHub stars, it provides kernel-level isolation for running untrusted code safely and powers the sandboxing infrastructure behind AI coding agents like Devin and E2B.

Local microVM sandboxes for AI agent code execution

Microsandbox provides hardware-level isolated sandboxes for AI agents to execute code safely on local machines. Using libkrun microVMs and a 320ms bare-metal Linux/KVM homepage benchmark, it offers stronger isolation than Docker containers while staying lightweight enough for dev workstations. OCI-compatible with Python and Node.js runtimes. Apache-2.0 licensed with 6.6K+ GitHub stars.

Unified CI/CD and deployment platform with GPU support

Northflank is a unified platform for CI/CD, deployment, and infrastructure management that supports both traditional web applications and GPU-native AI workloads. It provides preview environments with full-stack database and AI model inclusion, BYOC deployment on any cloud, built-in observability, and automated scaling. Handles the complete deployment lifecycle from Git push to production with support for containers, databases, and GPU instances.

Daemonless container engine — a drop-in Docker alternative that runs rootless.

Podman is a daemonless, open-source container engine developed by Red Hat as a secure alternative to Docker. It can run, build, and manage OCI containers and pods without requiring a daemon process or root privileges. CLI-compatible with Docker commands, making migration seamless.

The minimal, blazing-fast shell prompt

Minimal, blazing-fast, cross-shell prompt written in Rust that works with Bash, Fish, Zsh, PowerShell, Ion, Elvish, and Nushell. Provides a single consistent prompt configuration across every shell, showing Git branch, language versions, and cloud context at a glance. Context-aware modules activate only when relevant, keeping startup fast. Configured through a simple TOML file, adding negligible latency. One of the most popular shell prompt tools in the developer community.

The modern terminal with AI

GPU-accelerated terminal built in Rust, now evolved into an Agentic Development Environment (ADE) used by 700K+ developers. Features block-based output navigation, AI command suggestions via the Oz orchestration engine, multi-line editing with syntax highlighting, and a built-in code editor with LSP support. Available on macOS, Linux, and Windows. Includes Warp Drive for sharing workflows, real-time session collaboration, and BYOK support for OpenAI, Anthropic, and Google API keys.

Your CI/CD scripts as code. Consistent, reproducible builds.

Build automation framework that combines Dockerfile and Makefile syntax for repeatable, containerized builds. Earthly runs every step in a container so builds produce identical results on dev laptops and CI, augmenting Make/Gradle/npm/cargo with cross-language reproducibility. Features parallel target execution, layer caching, multi-platform builds, and references across Earthfiles or repositories.

Programmable CI/CD engine that runs your pipelines in containers

Programmable CI/CD engine that replaces shell scripts and YAML with a typed API across 8 languages (Go, Python, TypeScript, Java, Rust, etc.). Dagger runs every pipeline step in containers for portable, locally-debuggable, cacheable builds that work identically on any CI platform. Includes GraphQL query optimization for parallelization, OpenTelemetry observability, and Dagger Cloud for managed compute.

Container orchestration at scale

Kubernetes (K8s) is the industry-standard open-source container orchestration platform originally developed by Google and now maintained by the CNCF. Automates deployment, scaling, self-healing, and networking of containerized workloads across clusters of machines. Runs everywhere from laptops (kind, k3s) to every major cloud (EKS, GKE, AKS), and is the foundation of modern cloud-native infrastructure.

Cloud platform for app deployment

Heroku is one of the original platform-as-a-service providers, letting developers deploy and scale web apps with a simple `git push heroku main`. Pioneered buildpacks, dyno-based scaling, and the add-on marketplace for managed Postgres, Redis, workers, and observability. Now a Salesforce product supporting Node.js, Ruby, Python, Java, Go, PHP, and custom Docker containers.

Build, share, and run containers

Industry-standard container platform for building, shipping, and running applications in isolated, reproducible environments. Package apps with all dependencies into portable containers using Dockerfiles and images. Docker Compose orchestrates multi-container applications. Docker Hub hosts millions of pre-built images. Docker Desktop provides GUI management on Mac/Windows. Essential for local development, CI/CD, and production deployments. The foundation of modern containerized infrastructure.
