It handles the full agent loop - tool use, MCP calls, human-in-the-loop approvals, sandboxes - and lets developers plug in any model, including local ones via Ollama. A benchmark on 14 DevRef Enterprise Bench tasks showed the same accuracy as Claude managed agents using Opus, but 30% lower cost, and 75% lower cost when paired with the open GLM model. The video walks through installing TrueForge via NPX, connecting tools (Exa, Linear, Notion, Daytona sandboxes), building a stock research agent, calling it via a Python API with SSE streaming, adding Matplotlib/PDF report generation through a sandbox, using skills like algorithmic art, and connecting a local Qwen model through Ollama. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is TrueForge and how is it different from coding agents like OpenCode or Aider? TrueForge is an open-source, MIT-licensed agent harness built by True Foundry that acts as a general-purpose runtime layer for agents, handling the full agent loop including tool use, MCP calls, human-in-the-loop approvals, and sandboxed code execution. Unlike coding-focused agents such as OpenCode or Aider, it is designed as a vendor-neutral alternative to Claude's managed agents, letting you build custom agents for any domain with any model, including local ones. _daily.dev helps developers evaluating agent runtimes like TrueForge compare architecture and cost trade-offs._ ### How much cheaper is TrueForge than Claude managed agents according to benchmark results? Running the same Opus model through TrueForge instead of Claude's managed agents cut costs by 30% while holding accuracy steady on 14 tasks from the DevRef Enterprise Bench. Swapping in the open GLM model within TrueForge pushed the savings to 75% versus Claude managed agents, again with comparable accuracy, according to a benchmark shared by True Foundry. _Developers deciding between managed and open-source agent runtimes track cost benchmarks like this on daily.dev._ ### Can I connect a local Ollama model to an open-source agent harness like TrueForge? Yes, TrueForge supports adding a custom provider pointed at Ollama's local base URL, letting you manually specify a model ID such as a Qwen 3.8 27B variant along with its context length and max output tokens. Once connected, the local model can be used interchangeably with hosted providers like OpenAI, Anthropic, or Gemini inside the same agent configuration. _daily.dev keeps developers running local-first agent stacks current on integrations like Ollama support._ --- Tags: [#open-source](https://daily.dev/tags/open-source), [#mcp](https://daily.dev/tags/mcp), [#claude](https://daily.dev/tags/claude), [#ollama](https://daily.dev/tags/ollama) [View this post on daily.dev](https://daily.dev/posts/trueforge-open-source-alternative-to-claude-managed-agents-1dd2izkgm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"TrueForge: Open-Source Alternative To Claude Managed Agents","url":"https://daily.dev/posts/trueforge-open-source-alternative-to-claude-managed-agents-1dd2izkgm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/trueforge-open-source-alternative-to-claude-managed-agents-1dd2izkgm"},"datePublished":"2026-08-31T16:26:34.925Z","dateModified":"2026-08-31T16:27:44.412Z","description":"TrueForge is an open-source, MIT-licensed agent harness by True Foundry that serves as a vendor-neutral runtime layer, positioned as an alternative to Claude's...","image":"https://i.ytimg.com/vi/lcMf0W0cxig/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/lcMf0W0cxig/sddefault.jpg","isAccessibleForFree":true,"articleSection":"NeuralNine","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"NeuralNine","logo":"https://media.daily.dev/image/upload/s--bMYO07OB--/f_auto,q_auto/v1777800757/logos/neuralnine?_a=BAMAMiWQ0","url":"https://daily.dev/sources/neuralnine"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/trueforge-open-source-alternative-to-claude-managed-agents-1dd2izkgm","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"open-source,mcp,claude,ollama","timeRequired":"PT21M","video":{"@type":"VideoObject","name":"TrueForge: Open-Source Alternative To Claude Managed Agents","description":"TrueForge is an open-source, MIT-licensed agent harness by True Foundry that serves as a vendor-neutral runtime layer, positioned as an alternative to Claude's...","thumbnailUrl":"https://i.ytimg.com/vi/lcMf0W0cxig/sddefault.jpg","uploadDate":"2026-08-31T16:26:34.925Z","duration":"PT21M","url":"https://api.daily.dev/r/1dd2IZkgM","embedUrl":"https://www.youtube.com/embed/lcMf0W0cxig"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"NeuralNine","item":"https://daily.dev/sources/neuralnine"},{"@type":"ListItem","position":3,"name":"TrueForge: Open-Source Alternative To Claude Managed Agents"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/trueforge-open-source-alternative-to-claude-managed-agents-1dd2izkgm#faq","mainEntity":[{"@type":"Question","name":"What is TrueForge and how is it different from coding agents like OpenCode or Aider?","acceptedAnswer":{"@type":"Answer","text":"TrueForge is an open-source, MIT-licensed agent harness built by True Foundry that acts as a general-purpose runtime layer for agents, handling the full agent loop including tool use, MCP calls, human-in-the-loop approvals, and sandboxed code execution.
