TL;DR
Python and AI-agent tooling dominate today's list, with developer/coding-agent infrastructure (MCP servers, trading and investing agents) appearing alongside privacy-first messaging and GPU computing. A long-running classic, free-for-dev's curated list of free cloud tiers, continues to climb steadily. The biggest single-day star gain goes to a high-performance MCP-based code intelligence server.
