Show HN: Durable Actors – OSS Durable Objects with configurable compute Hi HN, we're Thomas and Olivier from Terse ( https://ift.tt/QME4mbJ ) We've built Durable Actors, an open-source alternative to Cloudflare's Durable Objects. A Durable Object/Actor is a tiny server that handles one request at a time and has its own SQLite database. There's exactly one of each in the world and it is addressed by name. This is the perfect primitive for deploying multiplayer agents. Each agent can have its own Durable Actor, and each user can connect to that Actor via websocket. This is fully horizontally scalable. Your users can deploy and share agents at will without putting pressure on a central DB or websocket server. Durable Actors are also great for coordinating agents within a system. Since only one request is handled at a time, you can protect critical data such as a CRM and allow multiple agents to run concurrently without worrying about data races. The only alternative to this is Cloudflare's Durable Objects. However, there is extreme lock in (they pull you into D1, R2 + workers as well) and it wasn't originally built for agentic workfloads when it was released 5 years ago. Some notable projects built on Durable Objects include RampInspect, OpenInspect as well as the multiplayer frameworks Liveblocks and PartyKit. You can now build these kinds of projects on Durable Actors. Durable Actors is a version of DO that is built for concurrent agentic workloads. It is fully open source (MIT License) and includes a helm chart for you to easily self-host. Some key features: - Configurable compute: Specify CPU, RAM, data residency, idle-timeouts all in a decorator - No outer worker: We generate a type-safe client that you can just plug into your existing tech stack. - (coming soon, like today) Export SQLite table via CLI + MCP for exposing OLTP logs to your agent to help you debug. And our Performance Numbers (all p95): - Durable write: 85.6ms - Stateful Read (data in sqlite): 2.14ms - Actor Warm up: 334ms Here is a little counter demo so you can see the latency yourself: https://ift.tt/6s7Bo5f Would love your feedback! https://ift.tt/0VQC64O October 6, 2026 at 10:58PM

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints https://ift.tt/2yet5m3

Launch HN: PillarPlus (YC W20) – Automatically create construction blueprints Hey HN, we’re Naman and Rushil, founders of PillarPlus ( https://ift.tt/3dHyOBg ). We build software to automate the creation of construction blueprints. Specifically, our software generates engineering blueprints for air conditioning, ducting, fire, electrical, and plumbing services over the floor plan of the building. MEP (Mechanical, Electrical, and Plumbing) designs are a set of 15 technical drawings. We got started in India and are currently operating there, but MEP is standard enough that the software can apply to Western markets also, given that we have incorporated international building codes. Architects and contractors hire consultants, who still design the building manually. Complete dependence on human effort results in a process that is slow, error-prone and unreliable. Also, the number of consultants is limited resulting in higher fees, long delivery times and difficulty accessing the services. ...

Support San Francisco Small Businesses

Support San Francisco Small Businesses By Sophia Scherr As the coronavirus (COVID-19) continues to impact communities across the country and here in San Francisco, the San Francisco Council of District Merchants Associations (SFCDMA) is asking for your help in supporting small businesses and the people they employ during this unprecedented time. What can you do to support your favorite San Francisco small businesses? The SFCDMA asks that you consider donating and sharing a recently-launched   GoFund me campaign   with at least two other contacts to, encourage further online donations . With the mandatory shelter in place order still in effect and the potential for it to be extended, local merchants such as your favorite clothing store, bar, café, restaurant, hair salon, gym or spa, are all entering a period of concern and jeopardy.
