HackerRank Alternatives
Most people comparing HackerRank alternatives aren't unhappy with the product. HackerRank is still the default for coding assessments: 55+ languages, a large question library, pair-programming interviews, and now an AI interviewer. What changes people's minds is usually the plan. Starter is $79 a month billed annually for 60 attempts a year, attempts expire at the end of each cycle, ATS integrations start on Pro, and the API is Enterprise only. Here are the alternatives worth a look, starting with the ones that run code.
What is in this guide
TunnelQuiz wrote this guide and is one of the options in it. It is listed last because it doesn't run code yet. We read every vendor's own pricing and product pages on 9 and 10 October 2026, and where a price wasn't visible we say so rather than quote a third-party figure.
Quick Comparison
All prices are in US dollars, as each vendor publishes them.
| Tool | Runs code | Free option | Starting price | Best for |
|---|---|---|---|---|
| Codility | Yes, with engineering work simulations | Trial through its team | $1,200 a year, annual only, 120 invites | Engineering teams that want rigorous, research-backed tasks |
| CodeSignal | Yes, plus agentic assessments with AI tools | None for hiring | $79 a month billed annually, 60 credits a year | Tech hiring with AI proctoring and ID checks on every plan |
| Coderbyte | Yes, in a native IDE and VS Code | Free trial | $99 a month for 20 invites, unused invites roll over | Small teams with uneven hiring |
| HackerEarth | Yes, 40+ languages | Free trial | Not shown on its pricing page | Hiring challenges and hackathons |
| Adaface | Coding tests in 35+ languages | 14-day trial | $180 a year for 12 credits | Short tests for tech and non-tech roles |
| iMocha | Yes, 25+ languages in live coding | None listed | Quote only | Enterprise skills programs |
| TunnelQuiz | Not yet; AI-graded coding answers on Pro, execution coming soon | Free plan, 50 credits a month | $34 a month billed yearly, 150 credits a month | The proctored aptitude round before the coding test |
How We Compared Them
For a HackerRank replacement the first question is whether the tool runs code, so that is the second column. After that we compared what a candidate costs, what happens to unused attempts, how you can try it, and what the integrity checks cover.
Codility
Codility is the most direct replacement for engineering assessment. Its tasks are work simulations graded by running the code, its integrity tools look for pasted code, copied task text and similarity between candidates, and it is SOC 2 Type II and ISO 27001 certified. Starter is $1,200 a year, annual billing only, for up to 120 invites and one platform user. Scale is $6,000 a year for 300 invites, used at most 25 a month.
The catches: free trials are arranged through Codility's team, not self-serve, and video proctoring, ID verification, SSO and ATS integrations are on its quoted Custom plan.

CodeSignal's plans look a lot like HackerRank's. Build is $79 a month billed annually for 60 credits a year, or $99 a month billed monthly, and Grow is $479 a month billed annually for 420. The difference is what Build includes: AI proctoring and ID verification on the entry plan, plus agentic assessments where candidates work with tools like Claude and Cursor.
There is no free plan for hiring, and basic ATS integrations start on Grow.

Coderbyte is the flexible-budget option. The monthly plan is $99 for 20 invites, with $20 for each extra invite and unused invites rolling over. A pay-as-you-go pack is $500 for 50 invites that expire after 365 days, and Pro is $1,799 a year with unlimited candidates.
Several features cost extra on Pro: API and ATS integrations, SSO, branding, and premium analytics and proctoring are each $1,199 to $1,499 a year.

HackerEarth covers 1,000+ skills and 40+ programming languages, runs live coding interviews through FaceCode, and has AI screening and interviewing agents. Its other strength is reach: it runs hackathons and hiring challenges with a developer community it puts at 10 million.
When we checked, its pricing page showed plan names (Growth, Scale and Enterprise) but no prices, so ask for a quote.
Adaface
Adaface suits teams that hire developers and non-developers from the same tool. Its 500+ test library covers programming in 35+ languages alongside aptitude, personality and language tests, delivered in 40-minute, chat-style sessions. Annual credit packs start at $180 for 12 credits.
Credits expire a year after purchase, and each test costs 5 or 10 credits to set up. It has fewer deep engineering tasks than Codility or HackerRank.

iMocha runs code live in 25+ languages for its coding interviews and has a 10,000+ assessment library, with video proctoring, a safe browser and ID verification. It is now aimed at enterprises building skills programs, with Workday and SAP connectors.
Pricing is by demo and quote.

TunnelQuiz isn't a coding platform yet. Pro accepts coding answers in 19 languages and an AI grades them, but the code isn't run against test cases; that is coming soon. It earns its place on this list as the first filter in a large drive, where cost per candidate matters most: Essential gives 150 credits a month for $34 billed yearly, against HackerRank Starter's 60 attempts a year.
Every plan captures the candidate's whole screen every minute and detects a second display, and Essential adds webcam snapshots, AI browser-extension flags and live monitoring. Use it to cut the pool, then spend coding-platform attempts on the shortlist.
See TunnelQuiz vs HackerRankWhich One Should You Choose?
Start from what you are hiring for:
- Senior engineers, assessed on realistic work: Codility
- Engineers who will use AI tools on the job: CodeSignal
- A small team with uneven hiring: Coderbyte
- Employer branding through hackathons: HackerEarth
- Tech and non-tech roles in one tool: Adaface
- A large aptitude round before any of these: TunnelQuiz
Whichever coding platform you pick, check what happens to unused attempts or credits at renewal. HackerRank's expire each cycle, Coderbyte's monthly invites roll over, and Adaface's last a year.
Questions, answered
As of October 2026, HackerRank's pricing page lists Starter at $79 a month billed annually ($948 a year) for 60 candidate attempts a year, and Pro at $419 a month billed annually ($5,028 a year) for 360. Both have unlimited users, and HackerRank says annual billing saves 20%. Extra attempts are $20, and Enterprise is custom. Unused attempts expire at the end of each billing cycle.
For coding, it depends on volume. CodeSignal's Build plan costs the same as HackerRank Starter, $79 a month billed annually for 60 credits, and includes AI proctoring and ID checks. Coderbyte's $99 monthly plan suits uneven hiring because unused invites roll over, and its $1,799 Pro plan has unlimited candidates. For a non-coding aptitude round, TunnelQuiz's free and Essential plans cost far less per candidate.
Campus drives usually have two stages. For the first, a large aptitude and fundamentals test, cost per candidate and proctoring evidence matter most, which is where TunnelQuiz fits. For the coding round that follows, Codility, CodeSignal, Coderbyte or HackerRank itself will do the job.
Not yet. Coding answers in 19 languages are graded by AI on the Pro plan, without running the code. Running code against test cases is coming soon.
If your first round is a large aptitude test, TunnelQuiz runs it with whole-screen captures on every plan and a free plan of 50 credits a month.
