Confirm Render instance count when a GitHub tag is created
A release tag is the moment traffic is about to climb, and being under-scaled right then is a bad surprise. Notis watches for new GitHub tags and pulls your Render instance count, so you know you are ready to handle the load before you announce it.
Trigger
New Repository Tag Created
Triggers when a new tag is created in a GitHub repository. Monitors the repository's tags and fires an event for each newly created tag. The payload includes the tag name, the commit SHA and URL it points to, and archive download URLs.
Action
Get Instance Count
Tool to get instance count metrics for Render resources. Use when you need to retrieve instance count time series data for services, Postgres databases, or Redis instances. The resource parameter is required.
Why this helps
You cut a release tag and only remember to check whether you are scaled up after the traffic already arrived. By then, being under-provisioned is a live incident, not a checklist item.
- Confirm your scale before a release drives real traffic.
- Turn a tag into a readiness check instead of a hope.
- Catch an under-provisioned service before launch, not during.
- Remove a scaling review you keep forgetting to do.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Render to Notis once from the portal.
- 2Open your portal link and start a New Automation.
- 3Describe it plainly: when a new tag is created on GitHub, get my Render instance count and report it to me.
- 4Select the New Repository Tag Created trigger and choose your reporting channel.
- 5Create a test tag to confirm the instance count arrives.
Questions about this workflow
Can I limit this to version tags?
Yes. Describe the tag pattern you care about, such as tags starting with v, and Notis will only act on those.
What does instance count tell me?
It reports how many instances your Render service is currently running, so you can judge whether you are scaled for the release.
Is there anything to configure beyond the sentence?
No. One plain-language instruction and a trigger choice is the whole setup.

Supported Triggers and Actions
Notis builds workflows that link GitHub to Render. A trigger fires from one place; an action lands in another.
GitHub triggers
Render actions
New Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Add Header Rule
Tool to add a custom HTTP header rule to a Render service. Use when you need to configure headers like Cache-Control, security headers, or CORS headers for specific request paths.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Add or Update Secret File
Tool to add or update a secret file for a Render service. Use when you need to create a new secret file or update the content of an existing secret file.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Add Resources to Environment
Tool to add resources to a Render environment. Use when you need to associate services, databases, Redis instances, or environment groups with an existing environment.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Add Route
Tool to add redirect or rewrite rules to a Render service. Use when you need to configure URL routing, redirects, or rewrites for a service. Redirect rules send HTTP redirects to clients, while rewrite rules modify the request path internally.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
Create Custom Domain
Tool to add a custom domain to a Render service. Use when you need to configure a custom domain for a service.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
Create Environment Group
Tool to create a new environment group. Use when you need to create a shared collection of environment variables and secret files that can be used across multiple services.
New Repository Collaborator Added
Triggers when a new collaborator is added to a GitHub repository. Monitors the full list of collaborators on a repository and fires an event for each newly added collaborator. The payload includes the collaborator's GitHub username, account ID, profile URL, avatar URL, permission flags (pull, triage, push, maintain, admin), and assigned role name.
Create Environment
Tool to create a new environment within a Render project. Use when you need to set up a new environment for organizing services, databases, and other resources.
Commit Event
Triggered when a new commit is pushed to a repository.
Create Postgres Instance
Tool to create a new Postgres instance on Render. Use when you need to provision a new PostgreSQL database with configurable plan, version, and region.
