Builder.io Fusion
An AI agent from Builder.io that takes a Figma design, a Slack message or a Jira ticket and turns it into a working, reviewable pull request. It edits a live preview visually while writing real React code, and connects to your repo and components. Free tier to start; Pro is about $30/user/month plus usage credits that big jobs burn through fast.

Our take
Fusion is one of the more genuinely agentic design-to-code tools: it goes from a Figma file or a Jira ticket to a real PR you can review, not just a code snippet. The visual edit-and-preview loop is the draw. Watch the credit burn on large jobs, and treat its automation claims as vendor-reported - output still needs a developer's eye before it merges.
Best for
Product teams that want to turn designs and tickets into review-ready front-end PRs without hand-coding every screen.
Pros
- Goes from Figma or a ticket to a real pull request
- Visual editing stays in sync with actual React code
- Connects to your repo, design system and components
- Free tier to try before paying
Cons
- Credit-based usage gets pricey on big tasks
- Generated PRs still need human review
- Outcome claims are vendor-reported, not benchmarked
How it compares
Against v0 and Lovable it leans more agentic and enterprise - ticket-to-PR and design-system awareness rather than a fresh greenfield app - which is its edge and its complexity.
Full review
Builder.io has spent years on visual development and Figma-to-code; Fusion is its agent layer. You point it at a design, a component library or a work item, and it plans the change, writes the code, shows a live preview you can nudge by clicking, and opens a pull request against your repo. The pitch is that the design-to-code gap finally closes without throwing away your existing stack.
For an Indian team shipping web front-ends, the free tier is a real way to test it on a couple of screens before committing. Just go in clear-eyed on cost: pricing is per-seat plus AI credits, and a heavy refactor can eat credits quickly. As with any coding agent, the PRs are a strong starting point, not a substitute for review - and the headline automation numbers come from the vendor, so we score the outcome conservatively.

Composio
Composio provides the execution infrastructure that connects AI agents to real software. It sits at the tooling and connectivity layer of the agent stack, giving developers one framework - SDKs, a CLI and 850+ pre-built connectors - to let agents act across apps such as GitHub, Slack and Salesforce. It handles the hard parts: complex authentication and OAuth, plus remote sandboxed environments for safe execution, exposed over the Model Context Protocol so agents can reason and then reliably take action. The platform is built for production, with SOC 2 and ISO 27001:2022 certifications and deployment across public cloud, VPC and on-premises. Composio operates from San Francisco and Bangalore and raised a $25M Series A led by Lightspeed, with angels including Vercel's Guillermo Rauch and HubSpot's Dharmesh Shah.
