Manage AI agent spec files across developer teams
The Problem
Developers iterating on agentic solutions need tools to track and constrain AI agent behavior reliably, turning to platforms like Vellum for IDE-like support and regression testing[1]. Two independent builders shipped products for structured spec formats on the same day on HN, indicating acute pain in managing specs across teams. Enterprises spend on orchestration tools like Agentforce and Copilot Studio, with reported $500k savings, but lack spec-specific management[6].
Real Demand Evidence
Found on Hacker News ↗·Today
We keep getting inconsistent outputs from our AI agents. There is no agreed standard for how to specify what an agent should and should not do.
Core Insight
Dedicated management of structured spec files with version control and team collaboration to constrain agent behavior reliably, filling gaps in general-purpose tools like Vellum (no spec focus) and enterprise platforms (CRM-locked or low-code only).
- Target Customer
- Indie hackers and solo founders building AI agents, part of the 100k+ devtools users on platforms like HN/IndieHackers; expanding to small dev teams (5-20 devs) in agent-focused startups, within $10B+ devtools market.
- Revenue Model
- Freemium with free tier for solo devs (500k tokens/month like Vellum), Pro at $49-99/month for teams (undercutting Gumloop $97 and Copilot $200), Enterprise custom for multi-team spec orchestration.
Competitive Landscape
$0 for Starter (500k tokens/month), $250/month for Pro (5M tokens/month), Enterprise custom
Vellum focuses on tracking AI agent behavior through data flows, prompts, and regression testing but lacks specific support for structured spec files to constrain agent behavior across developer teams. It acts more as a general IDE without dedicated multi-team spec management features.
Custom enterprise pricing, contact sales
Merge Agent Handler is a platform for managing AI agents with pros/cons highlighted, but it does not emphasize structured spec formats or version control specifically for spec files shared across developer teams. Documentation suggests general management without spec-centric collaboration tools.
Starts at $2 per conversation, bundled in Salesforce editions from $25/user/month
Agentforce uses Agent Script for building agents with separate business logic to avoid hallucinations, but it is tied to Salesforce's CRM ecosystem and lacks open spec file management for independent developer teams outside sales/support workflows.
$200/month for 25,000 messages, $0.02 per additional message
Copilot Studio offers low-code agent building integrated with Microsoft 365 but does not provide structured spec files or version control tailored for constraining agent behavior in cross-team developer environments outside the Microsoft stack.
Free tier, Pro $97/month, Enterprise custom
Gumloop enables no-code autonomous agents with LLM/API integrations via instructions and app connections, but misses developer-focused structured spec formats and multi-team collaboration for reliable agent behavior constraints.
