Questions & Answers

As answered by people managing Fillout.com and StackSpend.app.

Why should a person choose your product over its competitors?

StackSpend.app's answer:

Legacy FinOps tools were built for the AWS-only era: they stop at a chart, bill you a percentage of your cloud spend, and can't explain what changed. StackSpend is different on three fronts โ€” it explains the cause of every spike (cost-to-code correlation), it covers AI/LLM spend as a first-class citizen alongside cloud, and it uses flat, predictable per-tier pricing so your cost-management bill never grows just because your cloud bill did. Setup takes minutes, and a 14-day free trial doubles as a free cost-health audit.

What makes your product unique?

StackSpend.app's answer:

StackSpend traces every dollar of cloud and AI spend back to the code, team, and pull request that caused it. Where traditional cost tools show you that spend moved, StackSpend's cost-to-code correlation shows you why โ€” automatically tying each anomaly to the deploy, config change, or PR behind it. It unifies traditional cloud (AWS, Azure, GCP, Snowflake) and modern AI spend (OpenAI, Anthropic, Cursor) in one view, detects anomalies daily instead of at month-end, and works from day one without a data team building dashboards.

How would you describe the primary audience of your product?

StackSpend.app's answer:

Engineering and finance teams who share responsibility for cloud and AI spend โ€” platform/DevOps engineers, engineering leaders, and FinOps or finance practitioners. It's built for teams running a mix of cloud infrastructure and AI/LLM services who need daily visibility and a shared source of truth, from fast-moving startups through mid-market and enterprise organizations.

What's the story behind your product?

StackSpend.app's answer:

StackSpend was built by engineers who spent years watching cloud bills climb โ€” and then watching AI make them climb faster. Founder Andrew Day spent a decade building large-scale systems in regulated banking, where every dollar of infrastructure was accounted for, then eight years in AI startups where teams spent across OpenAI, Anthropic, Cursor, and a dozen cloud services with no way to say why the bill jumped. The cause was almost always a code change โ€” a PR that flipped a model or widened a query โ€” but finance dashboards never connected spend to the code behind it. So StackSpend was built to close that gap and turn a monthly surprise into a daily signal.

Which are the primary technologies used for building your product?

StackSpend.app's answer:

StackSpend is a TypeScript monorepo (Turborepo). The web app is built with Next.js 15, React 19, and Tailwind CSS, deployed on Vercel. The backend API is a Node.js/Express service on Railway, with Supabase (PostgreSQL) for data and auth. Cost forecasting is powered by a Python FastAPI service using Prophet, pandas, and NumPy. AI/LLM features run through a dedicated agents service (Anthropic Claude), and the platform ingests cost data via native provider APIs and the open FOCUS standard.

Fillout.com Reviews

editlink.io vs Fillout: Which Tool Should You Use for Airtable Edit Links?
Fillout, like most form tools, is oriented toward creating records. Point it at Airtable and a submission tends to produce a new row. editlink.io is built to update an existing record in place โ€” same row, pre-filled with what's already there, saved straight back. If your records already exist and just need updating, that distinction is the whole ballgame.

Fillout.com mentions (9)

  • Looking for a form builder (similar to typeform) but can link dropdown questions to an external document.
    We build Fillout for just this type of reason. If you store the list of countries in Airtable, SmartSuite, HubSpot, Monday, Notion etc. You can have the options automatically sync to your Fillout form (you can't with Google Sheets currently but you can with all those other platforms).
