Swizzle is an open-source runtime for automations that your coding agent writes as plain Python, JavaScript or TypeScript. You describe the job, the agent writes the code once, and Swizzle runs it on your own server with schedules, webhooks, OAuth, encrypted secrets, retries, approvals and step-by-step logs. Give your agent the repo and it sets Swizzle up for you. Free under Apache 2.0.
