Savyre AI Coding Workflow

Savyre AI Coding Workflow

savyre.com

Savyre AI Coding Workflow is a structured, IDE-integrated framework that helps developers use AI responsibly across the software development lifecycle. Instead of moving directly from a prompt to generated code, Savyre guides every task through clear stages—from understanding requirements and exploring the existing codebase to design, implementation, testing, review and impact analysis. The workflow currently includes: Task Input → Requirement Analysis → Codebase Discovery → Design → Plan Review → Implementation → Test Generation & Review → Code Review → Impact Analysis → Final Submission At each stage, developers review and validate the AI-generated output before progressing. The approved output becomes the input for the next stage, creating clear checkpoints, consistent documentation and end-to-end traceability. Savyre works inside VS Code and Cursor and complements existing AI coding assistants rather than replacing them. It helps developers maintain context, identify hidden dependencies, review implementation decisions and understand the wider impact of code changes. With Savyre, teams can: * Reduce unstructured “vibe coding” * Improve the quality and consistency of AI-assisted development * Create stronger testing and review checkpoints * Preserve technical decisions and development evidence * Increase developer understanding and ownership of AI-generated code * Give engineering leaders better visibility into how software is being built Savyre is designed for individual developers, engineering teams and organisations that want the speed of AI-assisted coding without losing structure, quality, accountability or control. Savyre turns AI-generated code into accountable engineering.

Reqit

Reqit

reqit.dev

Reqit is a local-first, git-native API client built for developers who want their API collections to live alongside their code instead of locked away in someone else's cloud. Every collection is stored as plain files in your repo, so requests, environments, and test suites version naturally with git: diffable, mergeable, and reviewable just like any other part of your codebase. Beyond the basics of sending requests and organizing collections, reqit includes a mock server for simulating endpoints during development, a Collection Runner with assertions for automated testing, and full OpenAPI import/export so you can move in and out of existing specs without friction. It supports mTLS client certificate authentication for teams working with secured internal APIs, and a BYOK (bring-your-own-key) AI layer that lets you plug in OpenAI, Anthropic, Gemini, Groq, or Ollama for AI-assisted workflows inside the app. For teams building AI agents, reqit ships with its own MCP server, exposing your API collections as tools an agent can call directly, plus Agent Lens, a linter and eval workbench that checks whether your API surface is actually "tool-ready" for agentic use. Collections can also be published via Collection Showcase, with support for custom domains, making it easy to share polished, browsable API documentation without standing up separate infrastructure. The whole experience is wrapped in a distinctive visual identity, deep blacks accented with a signature cyan, giving reqit a sharp, focused feel that stands apart from the cluttered, cloud-first tools it's meant to replace. At its core, reqit is about giving developers ownership: your API workflows shouldn't be trapped in a vendor's database. They should be yours, versioned, portable, and as hackable as the rest of your stack.
