Stop shipping prompts
as code deploys.

The problem

Your prompts live in code. They shouldn't.

Before Peekr Prompts

# prompts.py — buried in codebase

SYSTEM_PROMPT = """

You are a helpful assistant.

Answer using the context below.

"""

last updated: who knows

last tested: never

rollback: git revert + PR + deploy (15 min)

who changed it: check blame

⚠ Prompt broke production. Rollback takes 15 minutes.

With Peekr Prompts

# agent.py — one line, always current

import peekr

prompt = peekr.prompts.get(

name="rag_answer",

)

system = prompt.render(lang="en")

✓ Update from dashboard — no deploy needed

✓ Roll back in one click

✓ A/B test v3 vs v4 automatically

✓ Full version history with diffs

Why this matters

Four pain points. One fix.

🚀

Every prompt change is a deploy

Tweaking a system prompt means a PR, a review, a CI run, and a deploy. For a text change that takes 10 seconds to write.

🔥

Rollbacks take as long as deploys

Something went wrong in production. The fix is reverting a string. But you're waiting 15 minutes for CI to run.

🧪

A/B testing prompts requires custom infra

You want to test two versions of a system prompt. Now you're building an experiment framework instead of your product.

🔒

Non-engineers can't touch prompts

Your product manager has a better idea for the prompt wording. They can't change it without a developer.

GitOps mode

Prompts in your repo.
Deployed with your code.

Define prompts in peekr.yaml and run peekr deploy in CI. Prompts ship when your code ships — version-controlled, reviewable, and automatically synced to Peekr Cloud. Update from the dashboard between releases.

✓ Full git history for every prompt change

✓ PR review before activating in production

✓ Dashboard updates take effect on next SDK startup

✓ Compliance teams can review wording without code access

Features

Everything prompts need in production.

Version history

Every change creates a new version. See the diff, who changed it, when. Roll back to any version in one click.

Deploy from the dashboard

Activate a new version without a code push. The SDK fetches the active version at startup automatically.

A/B testing built in

Split traffic between two prompt variants. Peekr's observability tracks cost, quality, and latency for each.

Variable templating

Use {{variable}} placeholders. Render them at runtime with your context — keeps templates clean and reusable.

peekr.yaml — GitOps for prompts

Define prompts in peekr.yaml and run peekr deploy in CI. Prompts ship when your code ships — no extra steps.

Non-engineer access

Product, legal, and compliance can edit prompt wording from the dashboard. Developers review before activating.

Stop hardcoding your prompts.

Free tier includes unlimited prompts. No credit card. The next time something breaks in production, you rollback in one click — not one deploy.
