SuperPrompts 2 is out

SuperPrompts

System prompts out of your codebase. Edit in a UI, publish a version, fetch it with one call.

Every save is a version. Production points at one of them. Your app reads it over REST, the Node SDK, or straight from Claude Code through MCP. No redeploy for a wording change.

# System Context
You are a helpful customer support assistant. Your role is to assist users with their inquiries in a professional and friendly manner.
# Tone Guidelines
Be empathetic and understanding. Use clear, concise language. Avoid technical jargon unless necessary. Always maintain a positive tone.
# Task Rules
1. Always acknowledge the user's concern 2. Provide specific solutions 3. Offer follow-up support 4. Escalate if needed
# Examples
User: "I can't log in" Assistant: "I understand how frustrating that is. Let's troubleshoot together. Have you tried resetting your password?"
# Output Format
Respond in plain text. Structure your response with: - Acknowledgment - Solution - Next steps

Using OpenAI Prompt Objects? The v1/prompts API shuts down on 30 November 2026.

Move each prompt id across in a few minutes, keep variables and versions, and stop depending on one vendor's dashboard. The migration guide walks through the three steps.

Read the migration guide

The prompt lifecycle, without the observability suite

Write, version, publish and fetch system prompts. That is the whole product, and it is done properly.

Write

Sections, not one giant textarea

Split a system prompt into named sections you can reorder, toggle and diff. Or flip to markdown mode and edit the whole thing as text.

Template variables

Write {{ customer }} anywhere. The API lists the variables a prompt needs and the SDK fills them in at runtime, strictly if you want.

Import from markdown

Paste or drop a markdown file. Headings become sections. Prompts you already have are in the editor in a few seconds.

Ship

Every save is a version

Versions are content-addressed hashes, like git. Compare any two, write a commit message, and see who changed what.

Publish and roll back

Production points at one version. Publish a new one when it is ready, roll back in one click when it is not. Apps pick it up on the next request.

Fetch latest for staging

Ask for ?version=latest in staging and production by default everywhere else. Same prompt id, no separate copies to keep in sync.

Integrate

One REST call

GET /api/v2/prompts/:id returns the assembled text, sections, tools and variables. Read, write and publish over HTTP with a project key.

Node SDK

npm install superprompts. Cached reads, variable compilation, typed responses, zero dependencies. Every other language reads the same prompt over REST.

MCP server for Claude Code and Cursor

Add one MCP endpoint and your coding agent can list, read, edit and publish prompts without leaving the terminal.

Trust

Playground with your own keys

Run any version against OpenAI, Anthropic, Google, Mistral or xAI side by side before you publish. Your provider keys, your bill.

Prompt Guard

Optional anti-injection instructions appended to served prompts. Blocks the usual "reveal your system prompt" attempts. Turn it off per request.

Projects and teams

One project per app, one API key per project. Invite teammates so the person who owns the words can change them without a deploy.

What the API hands back

One response has everything your call to the model needs. No client library required, though the Node SDK saves you the caching and variable code.

prompt: the assembled system message
sections: id, title and content, in order
variables: every {{ placeholder }} the prompt expects
tools: OpenAI-compatible function definitions
version and production_version: what you are actually running
// GET /api/v2/prompts/:id
{
"prompt": "<role>You help {{ customer }}…",
"sections": [ { "id": "role", … } ],
"variables": ["customer"],
"tools": [ { "type": "function", … } ],
"version": "8481c55…",
"production_version": "8481c55…",
"label": "production"
}
Enterprise Security

Built-in Guardrails

Protect your AI applications from malicious attacks. Our intelligent guardrails system automatically detects and blocks prompt injections, prevents system prompt leaks, and secures sensitive information.

Prompt Injection Protection

Detects and neutralizes attempts to override system instructions or manipulate model behavior.

System Prompt Leaking

Prevents attackers from extracting your proprietary system prompts and instructions.

Sensitive Information

Automatically identifies and blocks attempts to access environment variables or keys.

AI Provider Integrations

The prompt is yours. So is the model.

SuperPrompts serves text and tool definitions; it never sits between your app and the model. The playground calls providers with keys you add.

Test before you deploy

Open the same version in several chat windows, one per provider, fill in the variables, and read the answers side by side before you publish.

How it works

Four steps, and the last three repeat for the life of the prompt.

1

Write

Paste the prompt you have or start from sections. Mark per-request values as {{ variables }}.

2

Publish

Save creates a version. Publish points production at it. History keeps every version with a diff.

3

Fetch

Replace the hardcoded string with one call: REST from any language, the Node SDK, or your agent over MCP.

4

Iterate

Try changes in the playground against real models, publish when it reads right, roll back when it does not.

Sections

A system prompt is several concerns stacked together: role, rules, examples, output format. Sections keep them apart so a diff shows what actually changed, and so a teammate can edit the tone without touching the rules.

# Role
You are the support assistant for {{ company }}.
# Rules
1. Never promise refunds.
2. Escalate billing disputes.
# Output format
Short paragraphs. No bullet lists.

REST API

Read, write and publish prompts over HTTP with a project key.

$ curl https://superprompts.app/api/v2/prompts/PROMPT_ID \
-H "x-api-key: sp_…"
✓ prompt, sections, tools, variables, version

Node SDK

Cached reads, variables, typed responses, no dependencies. Every other language uses the same REST call.

$ npm install superprompts
await sp.getPrompt(id, { variables: { customer } })
$ any other language
GET /api/v2/prompts/:id -H "x-api-key: sp_..."
