Coasts (Containerized Hosts for Agents) is an open-source infrastructure layer that solves one of the practical problems of running AI agents in production: safe, isolated execution environments. When an agent needs to browse the web, execute code, access files, or call external APIs, it needs a sandbox that prevents it from accidentally (or intentionally) doing damage to the host system or other agents. Coasts provides a lightweight, Docker-based hosting layer with per-agent isolation and configurable capability grants. The core abstraction is the "coast" — a container configuration that specifies exactly what an agent can and cannot access: which file paths are readable or writable, which network endpoints can be called, what CPU/memory limits apply, and how long the agent can run. Agents are spun up in these containers on demand and torn down after completion, providing strong isolation with minimal overhead. The configuration is declarative (YAML-based) and composable, making it easy to define agent capability profiles. With 98 points on Hacker News and 39 comments — one of the higher engagement rates in the agent infrastructure space — Coasts is hitting a real need. As more teams build agent pipelines in production, the question of "what happens when the agent does something unexpected" becomes critical. Container-based isolation is the proven answer from the broader DevOps world, and Coasts applies it specifically to the agentic AI context.

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
“The declarative capability grants are exactly what I want — specify what an agent can touch and nothing more, spun up in a container with resource limits. This is the infrastructure pattern for production-safe agent deployment. YAML-based config means it slots naturally into existing IaC workflows.”
“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.”
“Container isolation is standard infrastructure work, and there are already several competing approaches (E2B, Modal, Daytona) with more polish and enterprise backing. Starting a new OSS project in this space faces real network effects headwinds. The real question is what Coasts offers that existing solutions don't.”
“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.”
“The agent execution environment is going to become as important as the agent itself. As AI agents take real actions in the world — browsing, coding, executing — the infrastructure for capability isolation determines what's safe to automate. Coasts' open-source approach is important for avoiding vendor lock-in in this critical layer.”
“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.”
“Deep DevOps infrastructure work — not relevant to creative workflows unless you're running a production AI system. The people who need this will know they need it; everyone else should wait for higher-level abstractions that hide the container complexity.”
“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.”
