host provides a suite of open source tools designed to streamline the management of ephemeral compute resources, particularly for researchers and data scientists. The platform focuses on simplifying the process of finding, launching, and automatically managing EC2 instances, with features aimed at preventing unnecessary costs and operational overhead.
The toolset includes five components that each address a specific phase in the lifecycle of ephemeral compute. Truffle allows users to search for suitable EC2 instances by GPU model, vCPU count, memory, or natural language, and compares Spot prices across regions while checking service quotas. Spawn handles the rapid launch of EC2 instances—typically in under two minutes—using an interactive wizard, CLI flags, or by piping results directly from Truffle. Instances are tagged with a time-to-live (TTL) and are set to auto-terminate upon job completion, with idle detection based on CPU, network, processes, and sessions. Hibernation support and the ability to launch Spot, GPU, MPI clusters, and parameter sweeps are also included.
Lagotto monitors capacity across regions on a configurable schedule, which is particularly useful for securing scarce GPU resources. It can trigger instance launches, notifications, or webhooks, and supports Slack notifications when capacity becomes available. Spore-bot enables users to control their compute instances via Slack or Microsoft Teams, offering commands for status checks, starting, stopping, extending runtimes, and receiving lifecycle notifications through direct messages. OAuth integration allows for one-click workspace connections, and the bot can be accessed from any device.
For AI-driven workflows, the MCP Server integrates with MCP-compatible AI assistants such as Claude Desktop, Cursor, and Windsurf. This allows users to manage compute resources through natural language conversations, including searching for instances and managing their lifecycle. Installation is available for macOS, Linux, and Windows, with distribution via Homebrew, Scoop, and downloadable packages for Debian, Ubuntu, RHEL, and Fedora. 0 license.
spore.host sits in PulseGate's Hosting, deployment & PaaS category. It focuses on provisioning and managing ephemeral cloud compute instances for researchers and data scientists without manual intervention. spore.host is a B2B product aimed at researchers and data scientists needing cloud compute. There is a free tier. The product ships for the web, the command line, macOS, Windows, and Linux.
spore.host builds and maintains spore.host, and the product first shipped in 2025. The project is developed in the open on GitHub with 475 commits in the last 90 days. Among its 5 catalogued features are ephemeral compute, auto-termination, and idle detection. It exposes integrations via an MCP server.
