smolvm is a lightweight microVM runtime built in Rust on top of libkrun, designed specifically for sandboxing AI coding agents and untrusted code execution. VMs cold-start in under 200ms and ship as portable `.smolmachine` files — think Docker images but hardware-isolated. It supports macOS (Apple Silicon and Intel) and Linux, with opt-in networking so that untrusted code can't exfiltrate credentials or phone home by default. The project includes an explicit AGENTS.md to help coding agents understand how to use it, and was built with autonomous code execution in mind. When an AI agent needs to run user-submitted code or iterate on its own suggestions, smolvm gives it a proper hardware sandbox rather than a leaky container. Version v0.5.18 landed April 17, 2026. With AI coding agents increasingly running arbitrary code in tight loops, the security story around containerization has become critical. smolvm fills a real gap: fast enough to not break agentic workflows, isolated enough to actually protect the host machine and credentials. It surfaced on Hacker News with 259 points and strong technical discussion, suggesting genuine resonance with the developer community building agentic tools.

Social Fetch is a unified API platform that lets developers scrape profiles, posts, comments, videos, and transcripts from TikTok, Instagram, YouTube, X (Twitter), LinkedIn, and Facebook in real time. Built by indie developer Luke (lukem121), it unifies six social platforms behind a single TypeScript SDK with OpenAPI spec support and a pay-as-you-go credit model — no monthly commitment, no rate limits, 100 free credits to start. The core problem Social Fetch solves is fragmentation. Each major social platform has incompatible APIs (or no public API at all), constantly changing endpoints, and aggressive bot detection. Building and maintaining scrapers for all six platforms is a multi-month engineering effort that quickly becomes a maintenance burden. Social Fetch abstracts all of that away behind a clean, consistent interface that works today. For AI builders specifically, social data is increasingly the raw material for training data pipelines, competitive intelligence agents, content analytics, and trend detection. Social Fetch landed #3 on Product Hunt with 234 upvotes on launch day, suggesting significant demand. The pay-as-you-go pricing is appealing for projects with variable data needs, and the free credit tier lets teams evaluate it without any upfront commitment.
Reviewer scorecard
“This is the missing layer for anyone running AI agents that execute code. Docker containers have always been too porous for untrusted execution, and smolvm's sub-200ms coldstart means you can spin a fresh VM per agent turn without killing your latency budget. The AGENTS.md is a thoughtful touch — shows the authors actually understand the workflow.”
“Maintaining scrapers for six platforms is genuinely painful. If Social Fetch keeps up with API changes and anti-bot measures, the time savings alone justify the cost. The TypeScript SDK and OpenAPI spec mean zero friction to integrate.”
“At v0.5.18 this is still early software and the docs are sparse. libkrun has its own surface area of bugs, and running microVMs at agent-loop speed on macOS introduces a whole class of Apple Hypervisor Framework edge cases. I'd wait for v1.0 and a production case study before betting real workloads on this.”
“Scraping LinkedIn and Instagram at scale almost certainly violates their ToS, and both platforms have sued scrapers before. Using this in a production application carries real legal risk that isn't disclosed on the landing page.”
“Every autonomous agent that executes code needs a proper sandbox — not a polite request for the agent to be careful. smolvm represents the infrastructure layer that makes truly autonomous code execution safe enough to deploy at scale. This kind of primitive is foundational for the agentic software era.”
“Real-time social data is the nervous system of AI-powered market intelligence. A unified cross-platform API turns social media into a structured data source that agents can actually reason over.”
“For anyone building AI tools that touch code, smolvm means you can let your AI actually run things without fear. That unlocks a whole category of 'show me the output' UX patterns that weren't safe before. Less time explaining sandboxing to users, more time shipping features.”
“For content creators tracking trends and competitors across platforms, this is a tool that would save hours of manual monitoring weekly. The pay-as-you-go model means you only pay when you're actually using it.”
