What's New in Heym: OpenAI Codex Node

We're excited to announce the native OpenAI Codex node for Heym's workflow builder.

This addition brings fully automated, agentic coding capabilities directly into your visual workflows, enabling you to trigger autonomous coding tasks from cron jobs, webhooks, Slack messages, or GitHub events.

Authentication Made Simple

The Codex node introduces a groundbreaking authentication option.

Instead of managing OpenAI API keys and paying per token, you can now authenticate using your existing ChatGPT Plus or Pro subscription through a secure OAuth PKCE flow.

Heym securely stores and auto-refreshes your token bundle, eliminating surprise API bills while maintaining full functionality.

Traditional access-token mode remains available via an auth-mode toggle for teams that require it.

Seven Publish Modes

Choose exactly how your changes ship with flexible publish options:

• diff_only: Edit locally and return the patch with changed files, nothing pushed
• draft_pr: Commit, push, and open a draft pull request
• open_pr: Commit, push, and open a review-ready pull request
• commit_push: Commit and push a branch without creating a PR
• direct_commit: Commit straight to the base branch
• update_existing_pr: Add a commit to an existing branch or PR, opening one if none exists
• patch_artifact: Save the diff as a downloadable file and return a patchUrl

Agent Tool Integration

Attach the Codex node to any AI Agent so the agent can delegate coding tasks dynamically.

All node fields, including task prompt, repository, and branch, can be populated by the agent at runtime, enabling sophisticated multi-agent workflows.

Human-in-the-Loop Workflows

When Codex requires a product decision or missing information, it returns a needs_input status and pauses execution with a shareable follow-up link.

Route the question output to Slack, email, or Discord for team input.

Answering resumes the same Codex thread and execution, ensuring you maintain control without becoming a bottleneck.

Structured Results

Every Codex execution returns comprehensive structured output, including:

• A summary of changes
• Validation notes
• The complete git diff
• A list of changed files

This enables downstream nodes to process results programmatically and integrate with your existing CI/CD pipelines.

Isolated Execution

Codex clones repositories in an isolated runner environment, ensuring safe and predictable execution.

The node handles the complete lifecycle from repository cloning through code generation to result packaging.

Why It Matters

This release represents a significant step forward in workflow automation, enabling teams to save an average of 3.6 hours per developer per week on repetitive coding tasks while maintaining full control over how changes are integrated into their codebases.

What's Changed

• impl/share-dialog-wordings by @mbakgun in #281
• fix/dashboard-widget-trigger-guards by @ckakgun in #282
• Add canvas execution highlights by @mbakgun in #283

Heym adds Canvas Execution Highlights, a new debugging and observability layer for visual workflows.

After an execution completes, highlighted node outputs can be displayed inside a searchable and collapsible canvas panel. The feature supports live executions, restored execution history, and runs initiated through dashboard widgets.

For developers building complex agent and LLM workflows, this provides a faster way to understand what happened during execution without inspecting every node individually.

ClickHouse

Bring ClickHouse data into your automations:

• Connect to ClickHouse
• Run queries from workflows
• Use query results in AI and automation flows

Thanks for the great contribution! @eryue0220

Full Changelog: v0.0.50...v0.0.51

What's Changed

• impl/psql-vector-store by @mbakgun in #244

RAG just got simpler in Heym 0.0.50.

You can now run vector stores on Postgres with pgvector, not just Qdrant. Vectors live in Heym's own database, so there is no extra service to deploy.

Pick your backend per store, point a RAG node at it, done. Same insert, search, metadata filters, and reranking either way.

Existing Qdrant setups keep working, nothing to migrate.
