Vendor comparison
CoderPad vs. SkillFoundry
CoderPad is a live pair-programming interview: a shared editor, an interviewer, and a candidate working a problem in the same hour. SkillFoundry is an async assessment: the candidate works a repository task alone, and reviewers read an evidence-based result afterward. The useful comparison is which moment in the hiring loop each product serves.
Overview
CoderPad is built for the live interview. An interviewer and a candidate share an editor and work a problem in the same sitting. The format is pair programming: conversation, a problem that can move with the candidate, and a human in the loop who can ask why a line exists. That is a different job from an async screen, and it is a job worth doing when the person on the other side is someone you already intend to spend time with.
SkillFoundry is built for the assessment that happens around that live hour. The candidate completes a repository task on their own. Tests grade the code they submitted. An evidence trail describes how they investigated, how they used AI, and how they verified. A reviewer who was never on a call can still check the result. The same task and the same rules apply across the cohort, which is what makes an async screen comparable.
This page is a use-case split, and it is deliberately even. Live pairing and async evidence answer different questions. A hiring loop that needs both signals should keep both steps. A written assessment leaves out the pairing conversation. A live pad spends an interviewer on every applicant before you know who should be in the room.
When the live pad is the right instrument
Reach for CoderPad when the skill you want in that round is collaboration with another engineer, when you want the problem to change as you learn how the candidate thinks, and when you have interviewers who are prepared and available. The pad is the place the work happens, and the interviewer's account of the hour is part of the record. CoderPad is a purpose-built home for that session, including the scheduling motion that gets a live interview onto a candidate.
The strength of the format is the human. The same fact shapes its limit: two interviewers can walk out of similar sessions with notes that are hard to line up, and the AI rule in the room is the rule that interviewer enforced that day. Training and a shared rubric are how teams make live loops fair. That work lives in your interview program.
When the async evidence assessment is the right instrument
Reach for SkillFoundry when the pool is larger than the interviewer calendar, when every candidate should face the same repository task, and when a later reader needs a file. AI use follows the organization's rule for the assessment, and the score describes judgment applied to AI output under that rule for the whole cohort. Team benchmarking places the result next to engineers who already work on your team. Bias-audit support, logged human review, and retention controls belong to this step because the step can be automated.
The live conversation can still happen afterward, on a shortlist, with the evidence brief in front of the interviewer. That sequence spends senior time on people the record has already made legible. CoderPad remains a strong place to hold the conversation itself.

| Area | CoderPad | SkillFoundry |
|---|---|---|
| Primary format | A live pair-programming interview. An interviewer and a candidate share an editor and work a problem in the same sitting. | An async assessment the candidate completes without an interviewer on the call. Reviewers read the evidence afterward. |
| AI stance | The interviewer can see tools in use and ask about them during the session. The rule in the room is the rule that interviewer applies. | AI use follows the organization's rule for the assessment, applied the same way to the cohort. The score describes judgment applied to AI output. |
| Scoring evidence | The pad and the interviewer's account of the hour are the record. Depth follows the person who ran the conversation. | Trusted tests on the submitted code and a session evidence trail that a reviewer who was never on the call can still open. |
| Task style | Problems shaped for a live conversation: short enough to pair on, and flexible enough to follow the candidate's approach. | Repository tickets with acceptance criteria, closer to work the team ships, completed asynchronously. |
| Team benchmark | The interviewer compares the candidate with their experience of the team. The benchmark lives in that judgment and in your loop design. | A result can be placed against a benchmark of your own engineers on the same instrument. Plan fit is listed on the pricing page. |
| Compliance tooling | A live interview is a human decision, which many programs find easier to explain. Consistency across interviewers depends on training and a shared rubric. | Bias-audit tooling, logged human review, and retention controls for the automated assessment step, documented on the Trust page. |
| ATS/API | Connections oriented around placing a live interview on a candidate who is already in your ATS. | ATS-triggered assessments for Greenhouse, Ashby, and Workable, plus API keys and outbound webhooks, so the async screen starts from the req. |
| Who it fits | Teams that hire through live pairing and have interviewer time set aside for the people they want in a room. | Teams that need a consistent, reviewable assessment before they spend that live hour. |
| Interviewer time | An interviewer is part of the session. Signal quality tracks their skill, their questions, and their notes. | The assessment runs without an interviewer present. Senior engineers review a shortlist and the evidence brief. |

Verdict
Use CoderPad for live pair-programming interviews. Use SkillFoundry for async, evidence-based assessment. The products sit next to each other more naturally than they sit in place of each other. A loop that screens with a shared rubric and an evidence trail, then pairs live with the people who clear that screen, keeps both signals.
If you only have room for one step, choose from the question you must answer. Choose the live pad when the question is how this person works with another engineer in the room. Choose the async assessment when the question is what this person did on a repository task, how they handled AI, and whether you can show the evidence later.

Choose CoderPad when
You want a live pair-programming interview, with an interviewer in a shared editor, for candidates who already deserve that hour.
Choose SkillFoundry when
You want an async, evidence-based assessment on repository work, with the same rules for every candidate, before you spend live interviewer time.
Limits, stated plainly
A few limits, stated the same way on every comparison. Accounts can run an assessment now. Evidence-based results become the primary score after a readiness review. SkillFoundry allows the AI assistant where the organization permits it, and the score describes the judgment a candidate applies to AI output. The product is explicit that assistance can still slip past any single check, and that tooling alone does not remove bias. Bias-audit tooling, logged human review, and retention controls are part of the compliance story. SOC 2 Type II is an examination in progress. Trust & Compliance lists what is live and what is still in progress.
