Stop hardcoding
your prompts.
Echostash is prompt infrastructure for teams that ship AI products. Version control, evaluation, and deployment — built for developers.
Prompt spaghetti is real
Managing prompts in code leads to scattered, unmaintainable strings that waste tokens and require deployments for every change.
Scattered across the codebase
Centralized prompt library
No way to test prompt changes
Built-in evals and quality gates
Tokens wasted on irrelevant context
75% average token reduction
Logic in strings is a nightmare
Rich operator set + conditionals
Prompts that think before they speak
Echo DSL brings programming concepts to your prompts. Same template, different outputs based on context.
Variables render at runtime
Dynamic value injection with transforms and defaults.
Conditionals filter irrelevant sections
Runtime branching based on context variables.
Modular prompt blocks
Share sections across templates with partials.
LLM-evaluated conditions
AdvancedAI Gate for intelligent content selection.
Everything you need, nothing you don't
Only include relevant content. Filter out noise. Reduce token costs.
import { Echostash } from "@goreal-ai/echostash"
// Initialize the client
const es = new Echostash({
apiKey: process.env.ECHOSTASH_API_KEY
})
// Fetch, render, and convert to OpenAI format
const messages = await es.prompt("welcome-message")
.vars({ userName: "Alice", language: "English" })
