Codeaid vs HackerRank Chakra

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Codeaid

$129/mo 14 day free trial

A coding assessment platform built specifically for AI and machine-learning roles. Candidates work in real notebooks or GPU containers on messy datasets, and an AI interviewer builds the test and scores the work. The Team plan is $129/mo for 20 candidate invites a month, with a 14-day free trial.

Where Codeaid fits

  • AI startups hiring ML and generative AI engineers
  • Agencies pre-screening AI and ML candidates for clients
  • Companies upskilling software engineers into ML roles
  • Teams on Greenhouse, SmartRecruiters or Recruitee

HackerRank Chakra

$79/mo Free trial

HackerRank's AI interviewer for technical roles. It opens a real codebase in a live canvas with an AI coding assistant, watches how the candidate plans and builds, then asks follow-up questions to see whether they can defend what they shipped. Chakra comes with HackerRank plans, which start at $79/mo billed annually for 60 candidate attempts.

Where HackerRank Chakra fits

  • Engineering teams that want one AI round instead of a recruiter screen plus a take-home
  • Hiring AI engineers, forward deployed engineers and AI product managers
  • Teams already on HackerRank that want to test how candidates work with AI tools
  • Companies worried about candidates using interview cheating tools

Where they pull apart

Codeaid

Stands out: General coding test platforms struggle to tell whether someone can actually train and debug a model. Codeaid tests that directly, with datasets too large to paste into an AI assistant, and agencies can use it to pre-screen ML candidates before sending them to clients.

Watch out: Twenty invites a month on the Team plan is tight for volume hiring, so credit packs or Enterprise may be needed. It is narrow by design: for general software engineering or non-technical roles a broader assessment library fits better.

Not the right fit for

  • High-volume hiring for general developer roles
  • Non-technical assessments

HackerRank Chakra

Stands out: Most AI interviewers only talk. Chakra hands the candidate a real repository and an AI assistant, judges how well they use it, and ties every score to a moment in the transcript or the code. HackerRank says one Chakra session can replace the recruiter screen, take-home and engineer follow-up, and that candidates rated its 500,000+ beta interviews 4.8 out of 5.

Watch out: There is no Chakra-only price: it comes inside HackerRank plans that cap candidate attempts, with extras at $20 each. Its sample interviews are all engineering and AI product roles, so it is not built for non-technical hiring. On HackerRank's plans, ATS integrations start on Pro and the API and MCP are Enterprise only.

Not the right fit for

  • Non-technical or high-volume hourly hiring
  • Teams that want a standalone AI interviewer without a HackerRank plan
