Building autonomous AI agents. Notes from the team building Gravity. AI workflows, the future of recurring work, and what we learn along the way.
Prompt injection is the #1 risk on the OWASP LLM Top 10 (OWASP, 2025). Agents amplify every LLM risk by adding tools, persistence, and autonomy. This checklist gives you 47 controls across 10 categories. Each control…

A handoff is the contract between two agents (or one agent and a human) that specifies what gets passed, when, and what happens if the receiver is unavailable. Eight patterns cover most production cases. LangGraph,…

Naive retries amplify outages; smart retries absorb them. The Google SRE book defines a retry budget so retries can't exceed a fixed fraction of normal load (Google SRE, ch. 22). For AI agents the same logic applies…

You can build an AI agent in a weekend. Finding people who will pay to run it is the hard part. Most builders default to GitHub, get a few stars, and call it shipped. Three months later, the repo is collecting dust…

Builders ask the same question on day one: "How do I get my agent to the top of Gravity?" The honest answer is that we do not sell that spot. Not to the loudest builder, not to the highest bidder, not to ourselves.…

Most builders skip validation. They pick an agent idea on Saturday, build for 40 hours over two weekends, publish to a marketplace, and watch it sit at zero runs. According to CB Insights' 2024 post-mortem analysis…

n8n's community crossed 200,000 builders in 2024 according to n8n's own docs and community stats, and the GitHub star count sits north of 60,000. That's a small city of people who know how to chain APIs together. Yet…

If you can build an AI agent in n8n, LangChain, make.com, or any of the other workflow tools that have eaten the last three years, you can earn from it. The path from a working workflow to actual recurring revenue is…

Most first-time AI agent builders pick the wrong agent. They chase a clever idea instead of a boring, repeatable workflow that someone already pays a human to do. The five agents below all hit the same pattern: clear…

Restaurants typically run on a pre-tax margin of roughly 5 percent (National Restaurant Association, 2026) and food-away-from-home prices rose 4.1 percent year over year per USDA Food Price Outlook, 2026. A GM at an…

The short answer. Almost every profession can use an AI agent today, and the best results come from agents tuned to one job rather than tools that try to be everything. Gravity indexes expert-built agents across 55+…

Dental practices lose revenue in predictable places: 10 to 15 percent of scheduled visits to no-shows, recall lapse over 30 percent, treatment plans diagnosed but never scheduled, insurance verifications that consume…

Builders keep asking the same question: is this agent actually worth shipping? Most answers floating around treat AI agents like SaaS products with seat counts and CACs. They are not. An agent is a piece of software…

Most builders look at a marketplace headline split, 70/30, 80/20, 95/5, and stop reading. That's the expensive mistake. The percentage is the smallest variable in the equation. What matters is everything sitting…

Most teams don't need another tool to build an AI agent. They need an agent that already works. According to McKinsey's State of AI 2025 survey, 88% of organizations now report regularly using AI in at least one…

Open-source agent frameworks are not a competitor category to managed platforms. They are a different layer of the stack: libraries you build with, not products you buy. The choice between them comes down to…

Enterprise AI agent buying is a different category from founder buying. The shortlist is shorter, the requirements are heavier, and the procurement timeline is measured in quarters. The platforms that win enterprise…

"Cheapest AI agent platform" is the wrong question if you stop at the marketing page. The real cost includes LLM tokens, infrastructure, integrations, and time spent on glue code. A platform that looks free can be…

Bootstrapped founders read pricing pages differently. The question is not "what is the best agent platform" but "what is the cheapest agent platform that does not break when I scale to ten agents." The platforms that…

The phrase "personal AI agent" is a moving target. In 2024 it meant a chatbot. In 2026 it means an agent that runs for one person, on their behalf, against their actual apps and data, often without supervision. The…

The phrase "no-code AI agent" gets stretched. It can mean a chatbot wizard, a prompt chain in a spreadsheet, or a real autonomous runtime with a visual interface. This shortlist is the third meaning. Each platform…

Disclosure: Gravity is our own product. It is on this list for recurring SaaS ops, the job it was built for, and the reviews say plainly where a competitor is the better pick. Reviews are ordered alphabetically, not…

AI agent pricing pages are designed to look comparable when the models behind them are not. A flat-fee platform at one hundred dollars per month can be cheaper or more expensive than a usage-based platform at five…

"No vendor lock-in" is one of the most overused phrases on enterprise pricing pages. Every platform has some lock-in. The honest question is which lock-ins you can live with and which would be catastrophic if you had…

The "most integrations" claim is the cheapest one a SaaS marketing page can make. Counting connectors does not tell you whether the platform can do real agent work inside each one. A platform with five hundred…
