StackBlitz

Browser-based IDE for full-stack apps

Overview

StackBlitz is a browser-based development platform that lets developers build, run, and deploy full-stack web apps inside the browser using WebContainers, which run Node.js environments in WebAssembly for fast startup, offline use, and strong security. It supports popular frameworks like React, Vue, and Next.js and eliminates local setup. Bolt.new, launched in 2024, adds AI-powered coding that can generate, edit, and deploy apps from natural language while controlling the full development environment. The company differentiates itself by running development tooling entirely in the browser with WebAssembly and by combining AI-assisted workflows with cloud-like collaboration and enterprise features.

Bolt.new acquires Dokai to expand enterprise AI agents

Bolt.new has acquired San Francisco-based AI startup Dokai in its first acquisition, expanding its enterprise AI capabilities. Financial terms were not disclosed. Dokai developed autonomous agents that perform multi-step go-to-market activities, including prospect research and CRM operations, working directly inside enterprise systems. Co-founder Gerry Fernando Patia and the team will join Bolt.new's AI and machine learning organisation. The StackBlitz-owned platform allows users to build full-stack web applications through natural-language instructions. The acquisition will strengthen how Bolt.new's agents manage complex application builds and integrate with existing enterprise systems. Enterprise customers should see initial capabilities from Dokai's technology in late autumn 2026. Roughly half of Bolt.new's enterprise customers begin building applications before contracts are signed, with the average customer deploying their first application within 34 days. Dokai was backed by Character Capital and ERA.

Bolt.new launches Forge with 50X more open-source AI usage to train trillion-parameter model

Bolt.new has launched Bolt Forge, a research preview offering 50 times more usage on open-source AI models at no extra cost for individual Pro plan users. The service aims to make AI-powered software building accessible to more people by reducing cost barriers. Users who opt in share anonymised building sessions to help train an open-weight model. Bolt.new has partnered with Arcee AI to develop a trillion-parameter-class model using this data. All sessions from the initial training window, running from 14 September to 14 October, will contribute to the model's development. The arrangement requires explicit user consent through a one-tap opt-in when switching to Forge. Bolt.new anonymises shared sessions and removes sensitive information before transfer. Teams and Enterprise workspaces are excluded from the programme. The resulting model will be publicly available for download and use.
