description	Write a developer value proposition that is specific, provable, and free of puffery. Use when the messaging leans on "powerful," "better," "seamless," or "best-in-class," when claims have no proof, or when the same line is supposed to reach both the developer and the buyer.

The value prop that converts

"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)

1. Never say "better." Say better how, by how much, versus what.
2. Time savings must be specific. ❌ "saves developer time" · ✅ "8× faster builds, 2 hrs → 15 min" (attributed).
3. 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.
4. 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.
5. 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.
6. 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.
