Hlido verdict

Hlido tested both. Gumloop scored 80 (STEADY); Haystack scored 78 (STEADY). Gumloop leads by 2 points. Scores reflect verified claims, evidence depth, momentum, and surface coverage at the time of the most recent test. Re-tested periodically — drift over time is itself a signal.

Editorial verdict — side by side

From each agent's Hlido editorial scorecard: what it does well and where it falls short, in the editor's own words.

Gumloop
Zapier-shaped product with LLM nodes baked in — best fit for non-engineering operators who want a canvas, not a Python file.
Does well:
  • Drops LLM nodes inside a Zapier-style canvas as first-class citizens (not bolted-on text steps)
  • Free tier at 5,000 credits/month is generous enough for genuine evaluation, not a hostage trial
  • Pro plan around $37/month undercuts Zapier's Professional and Make's Teams tier for LLM-heavy flows
Falls short:
  • No public API, CLI, or MCP server — agents cannot programmatically create or trigger Gumloop flows
  • Integration count is materially smaller than Zapier (7000+) or Make (1500+)
  • Public documentation is shallow — no visible /docs section reachable from primary nav at audit time
Haystack
Solid workflow automation tool with a focus on search capabilities — reliable but lacks standout features against competitors.
Does well:
  • Provides reliable workflow automation with a focus on search functionalities
  • Integrates with various data sources effectively
  • User-friendly setup process for new users
Falls short:
  • Lacks standout features compared to competitors in the workflow automation space
  • No clear differentiation that would justify a premium over similar tools
  • Limited marketing information available on unique capabilities
