The prompt gold rush split in two: flea markets and factories. In 2026, both will make noise, but only one will survive scale.

My AI research agent pulled the raw data, and the pattern is loud. Consumers hoard templates. Teams need control. Governance keeps everyone out of the headlines.

The flea markets:

  • PromptBase, FlowGPT, PromptHero, and AIPRM put prompts on shelves. AIPRM claims over 2 million users. OpenAI’s GPT Store has millions of custom GPTs. Easy to browse, great for creators, but quality is hit or miss and prompts go stale fast.

The factories:

  • LangSmith, Vellum, PromptLayer, and Langfuse treat prompts like code: versioning, evals, tracing, releases. After Humanloop shut down in 2025, teams migrated here. Why? Copy-paste prompts in Notion break the minute models update.

The guardrails:

  • Lakera Guard, AWS Bedrock Guardrails, and open source Guardrails AI add jailbreak detection, PII filtering, and policy checks. Not sexy, but this is the seatbelt. Also the first thing auditors ask about.

Creation tools worth knowing:

  • Anthropic Artifacts for remixable mini-apps inside Claude. GPT Store for packaged “prompt apps.” Perplexity Collections to bundle prompts and research. PromptPerfect to clean prompts before they hit production.

What stings today: prompt drift, weak or fake evals, no single source of truth, and marketplace theft. Also, vendors die. If your prompts lived in a tool that shut down, you felt it.

Three app types to watch in 2026:

  1. Prompt firewalls - centralized governance in front of agents and models. Good for enterprises, annoying if it slows users or blocks harmless stuff.
  2. Team prompt workspaces tied to data and agents - prompts as first-class artifacts with CI-like evals. This is where real teams land.
  3. Vertical prompt packs baked into SaaS - opinionated templates inside CRM, design, and education. Marketplaces distribute, SaaS retains.

My take: prompts are graduating from hacks to assets. If you’re building, pick a lane: firewall, workspace, or vertical pack. Another generic prompt library is noise. 🧰

What are you actually using today, and what quietly died on your team?
