CodeRifts detects breaking changes in OpenAPI schemas on every pull request. It scores risk across 4 dimensions (revenue impact, blast radius, app compatibility, security), enforces governance policies before merge, and translates technical API changes into business impact — blast radius, affected clients, and estimated cost.
Works with GitHub, GitLab, Bitbucket, and any CI/CD pipeline. Zero config. Free to start.
Key features: - Breaking change detection with risk scoring (0-100) - Policy engine: breaking budgets, freeze windows, approval matrix - Economic impact estimation: cost and engineering effort - Security analysis: auth changes, sensitive field exposure - Auto-changelog and semver suggestions - GitHub App, GitHub Actions, GitLab CI, Bitbucket Pipelines, REST API, CLI

CodeRifts's answer:
Currently in beta, onboarding early adopters
CodeRifts's answer:
CodeRifts is the only API governance tool that combines breaking change detection with risk scoring, policy enforcement, and economic impact estimation — all delivered as a zero-config GitHub App. It does not just tell you what changed, it tells you how dangerous it is, who it affects, and what it will cost to fix.
CodeRifts's answer:
A field rename broke a POS system across 19 restaurants for a week. The PR passed code review, all tests were green, nobody checked the API schema. CodeRifts was built to catch this class of problem before merge — automatically, on every pull request.
CodeRifts's answer:
Most tools only diff your OpenAPI specs. CodeRifts goes further: it scores risk across 4 dimensions, enforces governance policies before merge, estimates migration costs in dollars and engineering hours, and works with GitHub, GitLab, Bitbucket, and any CI/CD pipeline. One YAML file replaces review meetings.
CodeRifts's answer:
Senior backend engineers, platform engineers, and staff engineers at companies with microservices architectures who need to prevent breaking API changes from reaching production.

This way, you transfer what you already know (problem-solving) but only change the syntax. Platforms like Hackerrank are also great to solve the same problem in different languages and learn from other people’s solutions. - Source: dev.to / about 1 year ago
Firstly, solve some common data structure problems with it. Implement some data structures like arrays, linked lists, stacks, queues, etc. You can check common problems on LeetCode, Hackerank or some other resources. - Source: dev.to / over 2 years ago
I don't have a consecutive internet connection and I can't keep up learning process so I started practicing in hackerrank.com I have started some challenges in python and c++ there. Thus I have no internet connection so I cannot practice if anyone know any alternative that works like Working: Gives a challange User sumbits code and it test into testcases.

An effective way to improve your JavaScript skills is working through coding challenges and exercises. Sites like ReviewNPrep, FreeCodeCamp, and HackerRank have tons of challenges that allow you to practice JavaScript concepts by building mini-projects and solving problems. These hands-on challenges force you to apply what you learn. Source: almost 3 years ago
I'm 18M Indian. Growing up I've always been a daydreamer, if you may. Since 8th grade - I'm fascinated by programming. And I'm good at it too. But I'm not cocky too. I wouldn't say I'm at an advanced level, but I can most probably solve any problem - in time - with my skills. I also keep my skills brushed by solving problems on Hacker Rank (every day or alternate days) and try my best to contribute on... Source: almost 3 years ago
