Products that do what Distributed Rate Limiter – 50K+ RPS, Redis-Backed, Production-Ready does
Hi HN! I built a distributed rate limiter using the token bucket algorithm with Redis backing. Key highlights: • 50,000+ requests/second throughput with <2ms P95 latency • Redis-backed distributed state for multi-instance deployments • 18 REST API endpoints for rate limiting, config, and monitoring • 265+ tests including load tests and integration tests • Docker/Kubernetes ready with comprehensive documentation Built with Java 21 + Spring Boot. Perfect for protecting APIs, microservices, or SaaS platforms from abuse. The pain point I solved: existing solutions were either too…

Dear startups, We've recently launched our service that helps deploy capacity across AWS EC2 spot to provide high availability and up to 90% discount on compute. Magic happens by us predicting spot prices and distributing capacity across dozens of uncorrelated Spot auctions to limit exposure to possible price spikes. As serial entrepreneurs we know first hand how important it is to iterate quickly and reducing the compute cost is one of the ways to approach it. If your company's AWS bill is significant (>$10k/month) and you have an interesting use case that we can discuss - we'd be…

Hey HN: I'm Kaveh, the founder of Usage (https://www.usage.ai/) We help companies drive down AWS costs. Why? Because the way it's done now is a pain. Stakeholders, especially engineers, are required to spend unnecessary time manually finding underutilized or overly expensive EC2s. We believe the optimization process should be done automatically through a series of sophisticated algorithms. At the moment, there are over 70,000 AWS EC2 prices - doing that manually just won't scale at most organizations. My background is in software engineering. Previous to founding Usage, I…

Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…

Hey HN, we’re the developers of OpenLake, an open source storage engine for offloading LLM KV caches from GPU memory into a shared tier of RAM and NVMe. We built OpenLake because KV caches are outgrowing GPU memory. A single 256K token conversation on Gemma 4 31B produces approximately 43GB of KV state, more than half the memory of an 80GB H100. The problem becomes even harder across a cluster: a prefix cached on one GPU host is unavailable when the next request lands on a different GPU, forcing the new GPU to repeat work the fleet has already completed. Once the KV cache is offloaded,…

Hey Hacker News! No one likes to code pricing; it sucks. It shouldn't take up my time, yet it always does - too much of it. And pricing always needs to change, eating up valuable dev hours. I created a simple pricing engine so that I could write all of my pricing rules & resource limits in a single YAML doc, then enforce them everywhere with a single policy check. It's simple, intuitive, versionable, auditable, and easy to reason about or change quickly without bogging my development down. My CTO friends liked the idea and wanted to use it, so I created this open-source library for everyone…
