"Better" is sloppy thinking. Better how, along what dimension, by how much, proven by whom? Developers test every claim you make. Give them numbers or give them nothing.
Use this when: your value prop contains puffery, your claims aren't attributed, or you're trying to make one sentence do the job of two audiences.
The core idea
Developers have a finely tuned BS detector and they will verify you. Specificity is credibility. Every strong dev value prop is: specific + provable + spoken in their language.
Framework: the value-prop rules (Frankl)
- Never say "better." Say better how, by how much, versus what.
- Time savings must be specific. ❌ "saves developer time" · ✅ "8× faster builds, 2 hrs → 15 min" (attributed).
- Two kinds of time, speak to both:
- Chronos (Alpha Dev): clock hours saved per week.
- Kairos (Empowered CTO): calendar time, weeks off a release cycle, competitive edge.
- The same product must land both. "Release fast or die" worked for developer and CTO.
- Every claim needs proof. A demo is the weakest proof (ideal conditions). An attributed testimonial (name + title + company + number) is the strongest. Anonymous quotes are assumed invented.
- Sell the category, not the solution. Talk about the problem and the need for "a tool like this"; don't proactively pitch features; it trips developer defenses.
- Never "pleased to announce" / "excited to share." No one cares how you feel.
Framework: the three dimensions of a dev value prop (Czakon)
A complete value prop answers all three, fast:
- What is it?: category / known-incumbent comparison / plain statement ("a Datadog alternative," "CI for monorepos").
- For whom / what use case?: the ICP and the job (from
who-is-this-for). - Why you over the 10 alternatives?: the legitimate, provable reason to exist.
Headline = what is it. Subhead = for whom / what job. For dev tools, weight the how over the why. Developers often already know why they hurt.
The puffery detector: flag and replace
| Banned | Why devs discount it | Replace with |
|---|---|---|
| Powerful | everyone claims it | the specific thing it does |
| Easy to use | they'll test it in 60s | time-to-value with a number |
| Best-in-class | says who, by what metric | the source or the number |
| Seamless integration | unprovable in the abstract | named integrations + logos |
| Industry-leading | says nothing | real share / user counts |
| Platform | hears: integration headache | the one job it does |
| Revolutionary / cutting-edge | pure air | name the actual technology |
Proof hierarchy (weakest → strongest)
your claim < a demo < a benchmark you ran < a named user's attributed result
Spend your effort at the right end.
Mistakes that look reasonable
- Adjective stacking: "powerful, seamless, intuitive." Three words, zero information.
- One line, two audiences: a Chronos-only message loses the buyer; a Kairos-only message loses the adopter.
- Unattributed social proof: "developers love us." Which developers? At which company?
- Leading with the why: for most dev tools the pain is known; lead with the how and the proof.
Your next 30 minutes
- Run your homepage copy through the puffery table. Delete or replace every hit.
- Rewrite your #1 claim with a number and an attribution (even a single named user).
- Write one Chronos line (hours/week) and one Kairos line (weeks/release). Make sure both exist.
- State your value prop as the three dimensions: what · for whom · why you.
