24 alternatives to SQLite for Rivet Actors – one database per agent, tenant, or document
Hey HN! We posted Rivet Actors here previously [1] as an open-source alternative to Cloudflare Durable Objects. Today we've released SQLite storage for actors (Apache 2.0). Every actor gets its own SQLite database. This means you can have millions of independent databases: one for each agent, tenant, user, or document. Useful for: - AI agents: per-agent DB for message history, state, embeddings - Multi-tenant SaaS: real per-tenant isolation, no RLS hacks - Collaborative documents: each document gets its own database with built-in multiplayer - Per-user databases: isolated, scales…
SQLite for Rivet Actors provides each actor—whether an AI agent, tenant, or document—with its own dedicated SQLite database, enabling millions of independent databases at scale. Built as part of the open-source Rivet… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hello! We posted a Show HN for Rivet last year for our container orchestration project (https://news.ycombinator.com/item?id=37188659). In that time, a lot has changed that I think HN will find interesting. Rivet is open-source actor infrastructure similar to Cloudflare's Durable Objects. Rivet itself already serves millions of MAU in production using our current container runtime – primarily for multiplayer games – and Rivet Actors are a new extension to support actor-like workloads. Rivet Actor's core primitives are RPC, state, and events. Actors are powered by Rust, V8…

We just launched Rivet, the open-source visual AI programming environment! We built Rivet, because we were building complex AI Agent applications at Ironclad. It unlocked our abilities here, and we're excited to make available to the entire community. Backstory: A few months ago, inspired by things like LangChain and LlamaIndex, we started building an AI agent that could work with legal contracts. Unfortunately, we couldn't just use retrieval augmented generation (RAG), because a lot of contracts are basically identical (many chunks with near-identical embeddings), except for a few key…

Pylar▲502Hey HN! We're Hoshang & Vishal, the team behind Pylar - a governed access layer between databases and LLMs. We previously led data and AI and we kept seeing the same problem across teams using LLMs internally: agents are great with unstructured data, but the moment you want them touching your actual systems of record — Snowflake, Postgres, CRMs, product DBs — everything becomes fragile, risky, or outright unsafe. Two issues show up every single time: 1. Agents over-querying They don’t understand cost. They’ll happily generate queries that blow up your warehouse bill. 2. Accidental data…

Hello HN! I'm building mvsqlite, a distributed variant of SQLite with MVCC transactions, that runs on FoundationDB. It is a drop-in replacement that just needs an `LD_PRELOAD` for existing applications using SQLite. I made this because Blueboat (https://github.com/losfair/blueboat) needs a native SQL interface to persistent data. Apparently, just providing a transactional key-value store isn’t enough - it is more easy and efficient to build complex business logic on an SQL database, and it seems necessary to bring a self-hostable distributed SQL DB onto the platform.…

I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…

At JigsawStack.com, we are using Redis by Upstash to store and validate API keys among other datasets for speedy retrieval. As we scaled to more Asian markets and added replicated nodes, the cost started to shoot up while performance got a lot worse. I discovered hosting SQLite on Fly which was crazy fast & cheap with the full power of a relational database but difficult to use and scale without writing tons of code & devops. Then I found Turso as a managed service which is pretty cool but again got really expensive and had to manage a bunch of replications manually and pay per replications…

Hyperterse▲86Hi HN, I’m Samrith, creator of Hyperterse. Today I’m launching Hyperterse 2.0, a schema-first framework for building MCP servers directly on top of your existing production databases. If you're building AI agents in production, you’ve probably run into agents needing access to structured, reliable data but wiring your business logic to MCP tools is tedious. Most teams end up writing fragile glue code. Or worse, giving agents unsafe, overbroad access. There isn’t a clean, principled way to expose just the right data surface to agents. Hyperterse lets you define a schema over your data and…

Hi everyone, I run a generative AI infra company, unified API for 600+ models. Our team started deploying AI agents for our marketing and lead gen ops: content, engagement, analytics across multiple X accounts. OpenClaw worked fine for single agents. But at ~14 agents across 6 accounts, the problem shifted from "how do I build agents" to "how do I manage them." Deployment, monitoring, team isolation, figuring out which agent broke what at 3am. Classic orchestration problem. So I built klaw, modeled on Kubernetes: Clusters — isolated environments per org/project Namespaces — team-level…

Hey HN! Today we're launching ActorCore (https://actorcore.org/), a stateful serverless framework that enables deploying Cloudflare Durable Object-like workloads to any cloud. If you're unfamiliar with stateful serverless: it's like the actor model, where each actor maintains its own isolated, persistent state. (Think Lambda functions with local storage & runs indefinitely.) It enables easily building long-running, realtime, durable, or local-first backends with the flexibility of serverless infrastructure. The most widely used implementation is Cloudflare Durable Objects,…
