## Dafthunk

:The platform is built on Cloudflare Workers, Workflows, Durable Objects, D1, R2, KV and the Workers Analytics Engine, which is what lets executions scale to zero when idle and back up under load without any infrastructure for you to provision. Durability and automatic retries are part of the runtime, so long sequences of steps survive restarts and transient failures.

AI sits at the centre of the node library: you can wire Anthropic Claude, OpenAI GPT, Google Gemini and Cloudflare Workers AI into text generation, summarisation, translation, sentiment analysis and vision steps, and hand results off to browser automation, media generation or third-party services. The project reports more than 470 nodes, 30+ AI models and a dozen integrations including GitHub, Discord, LinkedIn, Reddit, Google Calendar and Gmail. Because the whole stack is MIT licensed and developed in public on GitHub, you can fork it, self-host it or embed it in a commercial product without paying for the platform itself — you only cover the Cloudflare resources your workflows actually consume.

**Pricing & Plans:** Dafthunk is open source under the MIT license and free to use as a platform — there is no subscription for the workflow engine itself. Cloudflare charges for the underlying serverless resources your workflows consume (Workers, Workflows, D1, R2, Browser Rendering, Queues).

- **Visual drag-and-drop workflow editor:** Design automation pipelines on a drag-and-drop React Flow canvas instead of writing glue code, with live preview and versioning built in.
- **Serverless, durable execution:** Run workflows on Cloudflare Workers and Workflows with durable execution, auto-retry and scale-to-zero behaviour, so long-running jobs survive restarts.
- **Persistent storage and analytics:** Store workflow state and execution history in Cloudflare D1 SQL, R2 object storage, KV and the Workers Analytics Engine for persistent, queryable runs.
- **Flexible triggers and queues:** Start workflows from HTTP webhooks, Cloudflare Queues, cron schedules, email or a manual trigger to cover event-driven, queued and time-based automation.
- **Broad node and integration library:** Tap 470+ nodes across AI models, headless browser scraping and screenshots, image and audio generation, PDF creation and services such as GitHub, Gmail and Google Calendar.

**Strengths:** Fully MIT licensed with no enterprise tier or feature gating; Scales to zero when idle and up with demand on Cloudflare's serverless platform; Durable execution with automatic retries for long-running workflows; Large library of AI, browser, media and integration nodes behind one visual editor

**Limitations:** Requires comfort with technical concepts such as HTTP webhooks, queues and API credentials; Because it is a young open-source project, the node library and documentation are still growing; Not a fully managed turnkey product — you are responsible for your own deployment and maintenance; No official premium support tier or SLA as part of the MIT release

## Sim AI

Sim is an open-source AI workspace for companies that need to build, distribute and govern AI agents rather than run isolated prompts. It brings four connected products into one environment: Workflows for designing repeatable agent logic, Knowledge Base for grounding agents in internal documents, Tables for structured data agents can read and update, and Files for shared inputs, outputs and artifacts. A Logs product traces every run for debugging and cost visibility.
Teams can build through conversation in Chat, by arranging blocks on a visual canvas, or by writing code and using the CLI. Integration coverage is broad, with 270+ connectors spanning Slack, GitHub, Gmail, Notion, Salesforce, Jira, Linear, Supabase and Stripe, alongside every major LLM including OpenAI, Anthropic, Google, DeepSeek and xAI models. The Knowledge Base automatically syncs sources such as Notion, Google Drive, Confluence, Slack, GitHub and SharePoint, so agents answer from current content instead of stale snapshots.
Governance is the other half of the product. Administrators set permission groups for models, integrations and tools, define organization and per-member spend limits, retain audit records, and configure workspace data retention. Sim Cloud is available alongside self-hosting via Docker or Kubernetes under the Apache 2.0 license, with enterprise features gated by a license. The company publishes a Trust Center covering SOC 2 Type II, ISO 27001 and GDPR, and counts Rivian and eXp Realty as customers.

**Pricing & Plans:** Free forever on Sim Cloud with 1,000 one-time credits, 1 workspace and 5 GB storage. Pro is $25 per user/month (6,000 credits/month), Max is $100 per user/month (25,000 credits/month), and Enterprise is custom. Sim Cloud credits are worth $0.005 each, and the platform is free to self-host under Apache 2.0.

- **Build agents three ways:** Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
- **Knowledge Base with live sync:** Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
- **Tables and Files:** Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
- **Execution logs and cost tracking:** Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
- **Enterprise governance and self-hosting:** Manage SSO and SCIM provisioning, permission groups, model and tool access, spend limits, data retention and Docker or Kubernetes deployment.

**Strengths:** Open source under Apache 2.0 with free Docker and Kubernetes self-hosting; Four plans from Free to Enterprise, so teams can start without a sales call; 270+ integrations and every major LLM in one workspace; Knowledge Base auto-syncs from Notion, Drive, Confluence, Slack, GitHub and SharePoint

**Limitations:** Credit-based Cloud pricing can be harder to forecast than flat seat pricing; Enterprise governance features such as SSO, SOC 2 controls and self-hosted enterprise licensing sit above the Free plan; With 270+ integrations and four plan tiers, first-time setup requires deliberate configuration; Small Free plan limits (1 workspace, 5 GB storage, 30-day log retention) push team use toward paid tiers
