What It Is
Herbie is like a specialized calculator for computer programs. When computers do math with decimal numbers (like 0.1 + 0.2), they sometimes get tiny, unexpected errors because they can't represent all decimals perfectly. Herbie looks at mathematical formulas in your code and rewrites them to make these errors as small as possible, without changing the overall result.
This matters because even tiny numerical errors can compound in complex calculations, leading to incorrect results in critical applications like scientific simulations, financial models, or engineering designs. Herbie helps engineers and scientists ensure their computations are as precise and reliable as possible, avoiding costly mistakes or misleading data.
License Verdict
Unclear License — Proceed with Caution — Commercial Use Ambiguous • Consult Legal Counsel
The repository states its license as 'Other', which means there isn't a standard, well-understood license like MIT or GPL. This ambiguity makes it difficult to determine commercial use rights, including whether you can modify, distribute, or sell products incorporating Herbie. It's crucial to contact the project maintainers or consult legal counsel before building a commercial product.
How to Use It
Herbie is primarily a Racket package. You'll need to install Racket first, then use its package manager to install Herbie. There's also a web interface you can run locally.
Prerequisites:
- Racket
Estimated setup time: 10 minutes.
raco pkg install --auto herbie
racket -l herbie webWhat I'd Build With This
Precision Math Sandbox for Developers (micro-saas)
A web application where developers, data scientists, or financial analysts can paste mathematical expressions or small code snippets. Herbie processes them, showing the original and optimized versions, along with a report on potential error reduction. Users pay for advanced reports, batch processing, or integration with common programming languages.
Effort: 1 Week Build Time · Target: Software Engineers, Data Scientists, Financial Modelers · Pricing: $29/month
Numerical Stability API for Scientific Applications (saas)
An API service that accepts mathematical expressions or FPCore definitions and returns Herbie's optimized versions. This allows teams building scientific simulations, CAD software, or financial trading platforms to integrate floating-point optimization directly into their build pipelines or runtime environments, ensuring numerical stability without manual intervention.
Effort: 3 Months Build Time · Target: FinTech, Scientific Research, Aerospace Engineering Firms · Pricing: $199/month + usage
Custom Floating-Point Optimization & Auditing (enterprise)
Offer specialized consulting services to large enterprises in sectors like aerospace, defense, or pharmaceutical research, where numerical accuracy is paramount. Use Herbie as a core tool to audit existing codebases for floating-point errors, identify critical sections, and implement optimized solutions. This would involve custom integrations and training for their internal teams.
Effort: 6 Months to Establish · Target: Aerospace, Defense, Pharmaceutical, High-Frequency Trading · Pricing: $10,000 - $50,000+ per project
Sai Pavan Gopularam's Take
Herbie solves a genuinely hard and niche problem: floating-point precision. If you're building software where tiny errors can cost millions – think financial trading or aerospace – this is a goldmine. I'd explore selling an API service for $199/month to a dozen such companies, generating $2,400/month per customer.
Watch Out For
- Niche Problem: Floating-point errors are a specialized concern. While critical in some domains, many developers won't encounter issues severe enough to warrant dedicated optimization.
- Racket Dependency: Herbie is built on Racket, a less common language. This might be a barrier for adoption for teams primarily using Python, Java, or C++.
- "Other" License: The ambiguous licensing prevents commercial use without further investigation or explicit permission, posing a significant legal hurdle for product development.
