Sparkles

Sparkles (sparkles.dev) is a San Francisco developer-tools startup in Y Combinator's Winter 2026 batch building AI coding agents for a whole team, not just engineers. A technical owner connects the company's GitHub repositories and configures environment variables, after which any teammate on a company email address can describe a change and have an agent implement it inside an isolated sandbox and open a GitHub pull request for developer review. Positioned as "Lovable for existing projects," it lets marketers, designers, and operations staff ship safe code changes without needing to know Git or the command line. As of this profile Sparkles exposes only a marketing and product website plus legal pages; it publishes no public API, developer portal, SDKs, CLI, or OpenAPI, so this record captures verified company identity rather than an API surface.

Sparkles is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, AI Agents, Coding Agents, and GitHub.

Sparkles’ developer surface includes pricing, support, and 7 more developer resources.
