Lemonsignal vs TestGorilla

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

Starting price

Lemonsignal

$299/20 candidates Free trial

AI skills assessment for hiring: candidates do a real task in Claude Code, Claude Cowork, ChatGPT or Codex in the browser, and you get the finished work plus every prompt, command and edit as a session replay. Each candidate gets a role score and six AI skill ratings, each linked to the moment it is based on, and a question to ask in the interview. It is free on 3 candidates; packages start at $299 for 20 candidates and monthly plans at $449.

Where Lemonsignal fits

  • Teams hiring engineers who will code with AI assistants
  • Marketing and analyst roles where AI fluency matters
  • Hiring managers who want evidence of AI skill, not a self-rating

TestGorilla

$215/mo Free tier

Skills assessments before the interview. Free plan, then Core at $215/mo and Plus from $520/mo.

Where TestGorilla fits

  • Teams that want evidence before a live interview
  • Organisations on the major applicant trackers
  • Buyers replacing an enterprise assessment module
  • Small teams that can start on the free plan

Where they pull apart

Lemonsignal

Stands out: It tests how someone works with AI tools instead of banning them. Every score links to a timestamp in the session, so a hiring manager can watch the moment a candidate caught an AI edit nobody asked for, and the result ends with an interview question about the weakest moment. Tasks cover engineers, marketers and analysts, or you bring a real piece of work from your team.

Watch out: Pricing is per candidate who hands in the task, so screening at volume gets expensive ($10 per extra candidate on monthly plans). Getting started means a 30-minute setup call rather than self-serve signup, unused monthly candidates do not carry over, and it is a new product with no outside reviews yet.

Not the right fit for

  • High volume screening on a tight budget
  • Roles where AI tools are not used on the job

TestGorilla

Stands out: A large test library with anti-cheating measures and a genuine free plan.

Watch out: The jump from Core to Plus is steep, and it is tests rather than video interviewing.

Not the right fit for

  • Desks that need video as the product
  • Buyers who want one flat low price
