It seems that the dev tools that are getting the most attention this week are those that put collaboration, AI and automation at the core of every workflow, thoughtfully. Real-time copilots and code generators take on routine tasks without getting in the way. Observability and security platforms surface insight and enforce control at the right moments. This careful integration frees engineers to focus on building features and speeds up iteration.

🚀 3, 2, 1… Launches
Omnistrate Launches to Help Teams Build Their Control Plane in Days
Omnistrate is now live on YC, offering platform teams a fast way to build production-ready software distribution models like On-Prem, BYOC, SaaS, and Agentic SaaS. Think of it as the Control Plane-as-a-Service you don’t have to maintain. The platform runs inside your cloud account, supports custom infra setups, and integrates with Terraform, Helm, Kustomize, and more. Co-founded by Kamal Gupta and Alok Nikhil, Omnistrate aims to reduce the heavy lift of managing deployments across environments…and make it easier for dev teams to productise their infrastructure.

Praxos Debuts to Build AI Agents With Structured Memory
Praxos (YC S24) has launched a developer SDK that helps teams build reliable, stateful AI agents by turning their data into structured, queryable knowledge graphs. Created by Soheil S. and Lucas Urbisaia, Praxos addresses a common frustration: fragile agents that lose track of memory and struggle to operate across data sources. The product transforms everything from PDFs to databases into a unified Typed Knowledge Graph that powers smarter Q&A, better retrieval, and more stable workflows. It’s the first layer of what the founders call a full “AI kernel” for agentic systems.

Raindrop Deep Search is Announched to Track AI Failures in Production
Raindrop announces Deep Search, a new way for AI engineers to monitor live agent behavior at scale. Instead of relying on keyword or semantic search, Deep Search trains lightweight models that can classify issues across millions of real-world events, with just a few examples. Co-founder Alexis Gaubaannounced on Linkedin last week:
“Search for anything, and Raindrop automatically trains little models to accurately classify any topic or issue, across millions of events.”
The tool was built for engineers struggling to trace vague bug reports back to root causes. It’s already being used to identify hallucinations, broken tool calls, and UI failures in production.

Halluminate Creates Realistic Sandboxes for Training Browser AI
Halluminate (YC S25) is now live, providing datasets and realistic sandbox environments for training and evaluating AI agents built to use computers and browsers. Founded by Jerry Wu and Wyatt Marshall, Halluminate addresses key bottlenecks: safely training agents at scale, and creating high-quality datasets. Already trusted by top AI labs and browser-agent companies, their platform enables safer, faster, and more accurate agent development without relying on live, real-world tests.

🔦 DevTool of the Week: Liveblocks
Liveblocksearns this week’s spotlight with its version 3.0 release, making it the fastest way to add multiplayer collaboration and AI copilots to any web app.
Since launching in 2021 by Guillaume Salles and Steven Fabre, Liveblocks has let developers insert real-time features with minimal code. A $5 million seed round led by Boldstart in March 2022 fueled its growth. Accounts have doubled and connections have climbed more than ten-fold in three months, showing strong demand for its reliable real-time APIs.
This month’s 3.0 update blends collaboration and AI in one package. As CEO Steven Fabre shared on LinkedIn last week:
“Most companies are racing to add AI to their product. But in most cases, it ends up feeling like an afterthought. An AI chat widget that lives on the side. A helper that doesn’t understand what the user is doing. It hovers around the product—but never really becomes part of it. At Liveblocks, we took a different approach:
What if AI felt like a teammate? That question shaped everything.”
Ready-made React components now include intelligent copilots that understand context, take in-product actions, and guide users, no backend setup or AI expertise needed. Teams can drop in live cursors, comments, multiplayer editing, and AI assistants in minutes.
The launch hit #1 Product of the Day on Product Hunt, underlining its momentum.
Today, hundreds of companies rely on Liveblocks for design tools, dashboards, and shared documents. Next up, the team plans deeper AI integrations and expanded SDKs to power more complex workflows. If you’re building software where people and AI work side by side, Liveblocks 3.0 is a must-try.
