What it does
Opsler is the high-fidelity OS for US HVAC & plumbing fleets with 5-50 techs. Built on a serverless stack, we reclaim your control with real-time Invoice Guardrails, multi-truck Blind Inventory audits, and a built-in Drag-and-Drop Web Builder. Stop the 3% margin leak and bypass "Software Taxes" with our Zero-Fee QR payment infrastructure. From live tech tracking to GBB estimates, Opsler is the enterprise-grade replacement for legacy tools like Jobber. Reclaim your profit.
Run scheduling, work orders, estimates, dispatch, offline technician work and invoices in one field service platform. Free for 2 seats or $25/seat.
An offline technician app that closes out jobs and raises invoices without signal. A no-login customer portal with job history, payments and warranties. Good/Better/Best estimates so customers choose the right service. Start free forever on our Budding plan. A field service management system is the software a service business uses to take a job from the first phone call to the paid invoice: scheduling, dispatch, the work order, what the technician does on site, billing and the customer’s side of it. Shortened to FSM software , it is the category Opsler sits in. Most tools cover one slice of that, so a small shop ends up running four to six of them: a scheduling app, an invoice tool, a CRM,…from opsler.com

Bor – Open-source policy management for Linux desktopsAug 2026 · getbor.dev · ▲197Hi HN! I've been working on Bor, an open-source system for centralized Linux desktop management. Bor consists of a lightweight Go agent and a central server. Policies are streamed to clients over mTLS/gRPC in real time—no polling—and currently support Firefox, Chrome, KDE, dconf, polkit and package management, with more coming. Version 0.8 introduces several new policy types - Thunderbird, Microsoft Edge for Business and FirewallD zones, along with a number of improvements and fixes. I'd love feedback on the architecture, policy model, and whether this is something you'd consider for…
OpsFlow – Low-code DevOps – Webflow for infrastructure2022 · opsflow.app · ▲71Opsflow cofounder here! We launched a bunch of things recently, some of them well received (Terragen, AWS Bootstrap). It's no secret that AWS is hard, and our mission is to make it simple. What HN crowd helped us realise is that the UI was still not simple enough. Rather confusing in fact. So in the last couple weeks we have radically simplified it based on your feedback. We have removed the unnecessarily complex concepts like Services and Environments - it's just Apps now. All options are now on the new Settings screen. Instead of Infrastructure and Software deployments there is now a…

Automate your workflow in plain EnglishMar 2026 · operator23.com · ▲12operator23 lets non-technical operators describe a workflow in plain English and run it across their tool stack, hubspot, apollo, monday, google drive and others. no builder, no if-then config, just a description and a review step before anything runs. We talked to marketing ops people recently to validate whether we are solving the right problems. Three things came up every single time. Setup complexity. People are not afraid of automation in theory. They are afraid of spending two hours configuring conditions and field mappings, only to have something silently misroute. The config layer is…

Parallel agents, diff reviewer, and multi-model comparisons
Dev tools · May 2026 · kilo.ai
Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
