How do I install the Render skill?

Run npx skillmds add majiayu000/render-3 in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

What does the Render skill do?

Comprehensive guide for Render.com deployment and infrastructure management. Use when deploying apps to Render, configuring render.yaml Blueprints, managing web services/workers/cron jobs, setting up Postgres or Key Value datastores, configuring preview environments for PRs, or automating CI/CD with the Render CLI. Includes templates and validation scripts for common deployment patterns. It is listed under DevOps & Infra on SkillMD.

Is Render safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: makes network calls, reads secrets. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Render?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Render free to use?

Yes. Installing skills from SkillMD is free. This skill is licensed under Apache-2.

Render.com Deployment & Infrastructure

Render manages infrastructure through Blueprints - YAML configuration files that define services, databases, and environment groups as code.

Quick Start

# Install Render CLI
brew install render

# Authenticate
render login

# Set workspace
render workspace set

# List services
render services

# Deploy a service
render deploys create SERVICE_ID

# Open SSH session
render ssh SERVICE_ID

Blueprint Configuration

render.yaml Structure

Every Blueprint file is named render.yaml at the repo root:

previews:
  generation: automatic # Enable preview environments

services:
  - type: web
    name: my-app
    runtime: node
    plan: starter
    region: oregon
    buildCommand: npm install
    startCommand: npm start
    envVars:
      - key: APP_ENV
        value: production
      - key: DATABASE_URL

Multi-Environment Setup

Use Render Projects to organize services by environment:

projects:
  - name: my-app
    environments:
      - name: production
        services:
          - type: web
            name: my-app-prod
            runtime: node
            plan: standard
            buildCommand: npm ci && npm run build
            startCommand: npm start
            envVars:
              - key: APP_ENV
                value: production
        databases:
          - name: my-db-prod
            plan: pro-4gb
        networking:
          isolation: enabled # Block cross-env traffic
        permissions:
          protection: enabled # Prevent destructive actions

      - name: staging
        services:
          - type: web
            name: my-app-staging
            runtime: node
            plan: starter
            buildCommand: npm ci && npm run build
            startCommand: npm start
            envVars:
              - key: APP_ENV
                value: staging
        databases:
          - name: my-db-staging
            plan: basic-256mb

Preview Environments

Automatically create full environment copies for pull requests:

previews:
  generation: automatic # or manual, off
  expireAfterDays: 7 # Auto-cleanup

services:
  - type: web
    name: my-app
    runtime: node
    plan: standard
    buildCommand: npm ci && npm run build
    startCommand: npm start
    previews:
      plan: starter # Cheaper instance for previews
      numInstances: 1

databases:
  - name: my-db
    plan: pro-4gb
    previewPlan: basic-256mb
    previewDiskSizeGB: 5

Manual mode: Add [render preview] to PR title to create preview. Skip preview: Add [skip preview] to PR title.

See: references/preview-environments.md for setup guide.

Helper Scripts

This skill includes automation scripts in scripts/:

Script	Purpose
`init-blueprint.sh`	Interactive setup wizard for render.yaml
`generate-render-yaml.py`	Generate render.yaml from templates
`validate-blueprint.py`	Validate render.yaml syntax and references
`deploy-env.sh`	Deploy to specific environment
`env-sync.sh`	Sync env vars between local and Render

Script Dependencies

# Install Python dependencies
pip install -r scripts/requirements.txt

Usage Examples

# Initialize new blueprint interactively
./scripts/init-blueprint.sh

# Generate from template
python scripts/generate-render-yaml.py --template full-stack --name my-app

# Validate before deploying
python scripts/validate-blueprint.py render.yaml

# Deploy a service (uses service ID from Render Dashboard)
./scripts/deploy-env.sh srv-abc123

# List env vars for a service
./scripts/env-sync.sh list -s srv-abc123

# Compare local .env with Render service
./scripts/env-sync.sh compare -s srv-abc123 -f .env

Common Tasks

Add New Service to Blueprint

Add service definition to render.yaml
Run python scripts/validate-blueprint.py render.yaml
Commit and push to trigger Blueprint sync
Verify in Render Dashboard

Connect Services via Private Network

Services in same region communicate over private network:

services:
  - type: web
    name: api
    runtime: node
    buildCommand: npm install
    startCommand: npm start
    envVars:
      - key: CACHE_URL
        fromService:
          type: keyvalue
          name: cache
          property: connectionString # Uses internal URL

  - type: keyvalue
    name: cache
    plan: starter
    ipAllowList: [] # Only internal connections

Scale a Service

# Manual scaling
- type: web
  name: my-app
  runtime: node
  buildCommand: npm install
  startCommand: npm start
  numInstances: 3

# Autoscaling (Professional workspace required)
- type: web
  name: my-app
  runtime: node
  buildCommand: npm install
  startCommand: npm start
  scaling:
    minInstances: 1
    maxInstances: 5
    targetCPUPercent: 70
    targetMemoryPercent: 80

Add Persistent Disk

- type: web
  name: my-app
  runtime: node
  buildCommand: npm install
  startCommand: npm start
  disk:
    name: app-data
    mountPath: /data
    sizeGB: 10

Warning: Services with disks cannot scale to multiple instances.

CI/CD Integration

GitHub Actions Example

name: Deploy to Render
on:
  push:
    branches: [main]
jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - name: Install Render CLI
        run: |
          curl -L https://github.com/render-oss/cli/releases/download/v1.1.0/cli_1.1.0_linux_amd64.zip -o render.zip
          unzip render.zip && sudo mv cli_v1.1.0 /usr/local/bin/render

      - name: Deploy
        env:
          RENDER_API_KEY: ${{ secrets.RENDER_API_KEY }}
        run: |
          render deploys create ${{ secrets.RENDER_SERVICE_ID }} --output json --confirm --wait

See: references/ci-cd.md for more patterns.

Troubleshooting

Blueprint Sync Fails

Check YAML syntax: python scripts/validate-blueprint.py render.yaml
Verify service names are unique
Check region consistency (services referencing each other must be in same region)

Service Won't Deploy

Check build logs in Dashboard
Verify buildCommand and startCommand
Ensure PORT environment variable used (default: 10000)

Database Connection Issues

Use internal URL for same-region services
Check IP allowlist for external connections
Verify credentials in environment variables

Preview Environment Not Created

Verify previews.generation: automatic in render.yaml
Check PR title doesn't contain [skip preview]
Ensure Blueprint is synced and linked to repo
