Use Case Recommendations
Best for: here.now
here.now is web hosting designed for the moment an AI agent produces something that needs a URL. The interaction is deliberately minimal: tell the agent to publish to here.now, and the files are online at a random subdomain seconds later with no account, no project setup and no deploy configuration. Any agent that can make an HTTP request can use it — Claude Code, OpenClaw, Cursor, Codex, Amp or anything else — and the homepage hands you a setup prompt to paste into whichever one you use. There is also an installable skill (npx skills add heredotnow/skill --skill here-now -g) for agents that support that pattern. What gets published is whatever the agent just built and you now need to look at or send to someone: dashboards, prototypes, one-off tools, visualisations, reports, presentations, galleries, media files. Anonymous sites expire after 24 hours; registering a free account makes them permanent. Access control is more thought-through than the pitch suggests — URLs are random and unguessable by default, and a site can be password-protected or restricted to specific email addresses and domains. Workspaces give a team a shared subdomain with memorable URLs and member-only visibility by default. Third-party API keys can be attached as environment variables so a published site can talk to Stripe, Notion or OpenRouter. Files sit on Cloudflare's network and serve from the nearest edge. Custom domains are supported.
Ideal use cases:
- •Teams or individuals who need publish over plain http from any agent, no sdk required
- •Teams or individuals who need no account needed for a 24-hour site
- •Teams or individuals who need random unguessable urls, with optional password or email allowlists
- •Teams or individuals who need team workspaces with their own subdomain
- •Anyone focused on hosting workflows
- •Anyone focused on agents workflows
Best for: Spanlens
Spanlens is an MIT-licensed LLM observability platform whose main design goal is that instrumenting an application should cost one line rather than an afternoon. A CLI initialiser rewrites the call sites for you, after which every OpenAI, Anthropic and Gemini request is logged with its cost, latency and token counts, and multi-step agent workflows are traced into a Gantt view that shows where the time and money actually went. Beyond straight logging it runs three checks that most cost dashboards do not: anomaly detection on a three-sigma basis, PII and prompt-injection detection on request content, and a model recommendation pass that proposes cheaper models with a dollar-figure saving attached rather than a vague suggestion. Recent SDK releases added Ollama support for local models and LangGraph tracing, so self-hosted and graph-structured agent stacks are covered alongside the hosted APIs. The licensing position is the sharpest part of the pitch: the vendor states the project is fully MIT with no `ee/` folder, meaning there is no enterprise-only directory carved out of the open-source repository — self-host with Docker Compose and every feature listed on the paid tiers is available at zero cost. The hosted tiers exist to sell managed retention, seats and alerting rather than to gate functionality, and the site publishes direct comparisons against Langfuse and Helicone.
Ideal use cases:
- •Teams or individuals who need one-line instrumentation via a cli that rewrites your call sites
- •Teams or individuals who need request logging with cost, latency and token counts for openai, anthropic and gemini
- •Teams or individuals who need agent workflow tracing in a gantt view
- •Teams or individuals who need pii and prompt-injection detection on request content
- •Anyone focused on llm-observability workflows
- •Anyone focused on tracing workflows
