Twenty 2.0 turns our open-source CRM into a platform you can build on. Define your data model, custom objects, workflows, layouts, and widgets in code with our new SDK, shipped through your normal dev flow with the AI tools you already use. AI built in, custom agents, serverless functions, and full layout and navigation customization. Self-hostable. Fully yours.
Android CLI is a new agent-first toolkit that lets developers build Android apps directly from the terminal—faster and with less guesswork. It combines CLI commands, modular “skills,” and a live knowledge base to guide AI agents with best practices, enabling rapid setup, project creation, testing, and deployment while reducing token usage and speeding workflows up to 3x.
Every QA debug loop looks the same — CI fails, you open logs, Slack, Jira, Grafana. 45 minutes later, still no root cause. Ask AI fixes that. Type a question, get a rendered artifact — dashboards, sprint reports, test plans, stakeholder slides — built from your live Playwright data. No queries. No config. Just answers. Free 14-day trial. No credit card. Built by the founding team behind LambdaTest Test Insights.
21st Agents SDK is the fastest way to add an AI agent to your app. Define your agent in TypeScript, deploy in one command, and embed a production-ready chat UI with Built-in streaming, session management, usage billing, and observability — so you can focus on what makes your agent unique, not infrastructure. Backed by Y Combinator (W26).
NexaSDK for Mobile lets developers use the latest multimodal AI models fully on-device on iOS & Android apps with Apple Neural Engine and Snapdragon NPU acceleration. In just 3 lines of code, build chat, multimodal, search, and audio features with no cloud cost, complete privacy, 2x faster speed and 9× better energy efficiency.
LLMs are great at writing code but struggle with writing tool calls. Code Mode solves this by giving your model ONE powerful tool: a TypeScript execution sandbox with access to your entire toolkit. Complex, multi-step workflows thereby become a single batched execution. Independent studies show massive gains: 60% faster execution, 68% fewer tokens, 88% fewer round-trips, while Anthropic's research team found a massive reduction of 98.7% in token usage using CodeMode.
Hopx lets you spin up fully isolated Linux micro-VMs in ~100 ms — perfect for running AI agents, notebooks, or untrusted code safely at scale. Each sandbox runs in its own Firecracker microVM, with full state persistence, SDKs for Python, JS, Go, and more. No cold-start lag. No runtime limits. Just raw performance and security.
Start with an API spec. Generate SDKs in multiple languages and interactive API documentation tailored to your brand.
