Karat alternatives in 2026

Karat built the interview-as-a-service category and they execute it well. The reasons teams now look for alternatives are structural: per-interview pricing, panel-availability bottlenecks, and the absence of an AI-collaboration round. Here are the five platforms worth considering.

Why teams are looking

Karat works. The product does what it says — vetted contract engineers, structured rubrics, peer-engineer signal — and for the right organisation it is excellent. The alternative-search usually starts when one of three constraints binds.

Cost. Per-interview pricing scales linearly. A team running 200 first-round technical interviews per year is looking at $60k–$120k+ in Karat fees before any final-round work. Platform-priced alternatives can deliver the same first-round throughput for a fraction of that.

Scale. Karat’s panel grows steadily but cannot flex overnight. During hiring surges, scheduling slips. Platform interviewers do not have this constraint.

What is being measured. Karat interviewers test engineering judgment through a structured coding interview. They do not — by design — instrument how a candidate works alongside an AI agent. For roles where AI orchestration is the dominant on-the-job activity, this signal is increasingly central.

Top Karat alternatives in 2026

1. Basanite

Scalable AI interviewer

Basanite is the closest like-for-like replacement for Karat in the AI-native model. Round 1 is a 20–30 minute live voice conversation built from the candidate’s own CV, conducted by an AI interviewer trained on a documented inventory of 22 probing techniques. Round 2 — which Karat does not offer — is an AI Collaboration Workbench where the candidate ships work in a real codebase alongside their own AI agent, instrumented across six observable sub-dimensions. The report is dimension-by-dimension with verbatim candidate quotes pinned to every score above 3.

Best for: Engineering teams running 30+ technical hires/yr who want consistency at scale. Pricing: £400 / £1,500 / £3,300+ per month, no per-interview uplift. Link: basanite.co.uk · head-to-head comparison.

2. Mercor

Mercor is another AI-conversational alternative to human-led interviewing, with role-templated interview agents that deploy quickly. For teams that want to leave behind per-interview economics and prefer template breadth over CV-level personalisation, Mercor is on the shortlist. They do not currently offer a Round 2 AI Collaboration workbench.

Best for: Fast-moving teams that value role-template breadth and quick deployment. Link: Mercor alternatives.

3. CodeSignal Interview

CodeSignal’s interview product gives your internal engineers a polished live-coding environment to conduct the interview in. It is a different unit of substitution than Karat — you are not outsourcing the interview, you are scaffolding your internal interviewers. For teams that want to professionalise their own engineering panel rather than outsource it, this is a real option.

Best for: Teams keeping interviewing in-house but wanting better tooling. Link: CodeSignal vs Basanite.

4. HireVue Coding

HireVue Coding is the technical extension of HireVue’s async video platform — recorded answers plus a coding workspace, scored by AI. It moves away from the per-interview Karat model and toward an enterprise-platform model. The trade-off is that it is async rather than live and does not adapt to candidate answers in real time.

Best for: Global enterprises wanting a single platform for behavioural and coding screens. Link: HireVue vs Basanite.

5. In-house structured interviews

The unfashionable but legitimate alternative is to bring interviewing back in-house with strong structured rubrics. The cost is engineering time; the benefit is full control of signal definition and a peer-engineer signal Karat itself was trying to replicate. For small senior-band hiring programmes (under 20 hires/yr) where engineering capacity is available, this can outperform any platform — though most teams find the engineering opportunity cost too high.

Best for: Small senior-band hiring programmes with available engineering capacity. Link: FAQ on the underlying methodology.

FAQ

Why look for a Karat alternative?
Three reasons dominate the conversations we have with teams switching. First, unit economics: Karat is per-interview at typically US$300–600 per session, which scales linearly with hiring volume. Second, scheduling: panel availability becomes a bottleneck during hiring surges. Third, the AI-collaboration question: Karat interviewers do not have a structured way to measure how candidates work with AI agents, which is increasingly central to engineering roles.
Are AI interviewers actually as good as Karat’s human ones?
A senior human interviewer remains the highest-fidelity instrument available for evaluating a senior engineer. What AI interviewers offer is consistency at scale: the same dimensional rubric applied identically across thousands of candidates, with every score backed by a verbatim quote and a recording the hirer can audit any time. The right framing is not human-vs-AI but where in the funnel each is most valuable.
Can I bring my own rubric?
Basanite ships with eight metacognitive dimensions calibrated to engineering work, but customers regularly map their internal rubric into ours during pilot. Karat customers usually find the dimensional model is broader than the four-to-six-criterion rubrics they were using internally.
What happens to candidate experience when you remove the human interviewer?
Candidate sentiment is one of the clearest signals from our pilots. The Basanite voice conversation is rated, on average, as more humane than the platforms it replaces — including Karat, because the AI interviewer holds patience and consistency in ways even a vetted contract interviewer sometimes cannot. Every candidate also receives a personal feedback report regardless of outcome, which is more than most human-led platforms offer.
How does pricing actually compare?
For a team hiring 50 engineers in a year, Karat at conservative pricing ($300/interview, ~1.5 interviews per hire) runs around $22.5k. Basanite at Growth tier costs £1,500/mo / about £18k a year with no per-interview uplift inside the tier. The savings get larger as volume increases.
