Prometheus is Firecrawl's AI agent, launched in 2026, that turns a plain-English data request into a working TypeScript collector built on the Firecrawl SDK. It experiments against the live target site and tests the code before handing it back, then can run it on a schedule with automatic self-healing when the site's layout changes.
About Prometheus
Prometheus is a "Forward Deployed Agent for web data" built by Firecrawl, the web scraping API company founded in 2024 by Eric Ciarla and Nicolas Camara and backed by a $14.5M Series A from Nexus Venture Partners. Launched on Product Hunt in 2026 as Firecrawl's eighth product, Prometheus is built to replace the engineer who would normally be assigned to scope, test, and build a one-off web scraper for a specific data request. The product follows a simple loop: a user describes the data they want in plain English, such as "top 5 Hacker News posts" or "track this competitor's pricing page weekly." Prometheus then experiments against the live target site, writes a real Firecrawl SDK collector in TypeScript, and runs it to confirm the output before handing the code back. Unlike a black-box no-code scraper, the result is reviewable, versionable source code that a developer can read, modify, and run anywhere. Teams can either deploy the generated collector themselves, or let Firecrawl host and run it on a schedule with automatic error recovery when the target site's layout changes. This makes Prometheus most useful for data engineers building RAG pipelines, AI agent developers who need self-healing data feeds, and founders or growth teams who know what data they need but have no spare engineering time to build it. Firecrawl sells no separate license for Prometheus; usage draws on Firecrawl's existing credit-based plans, which span a free tier through a paid Scale tier, with custom Enterprise pricing above that. Prometheus is web based, accessed through Firecrawl's platform, and integrates with the Firecrawl SDK and MCP server used in Cursor, Claude, and Windsurf. During its launch weekend, Prometheus was offered free to try directly through Claude, and Firecrawl said the agent had already been saving its own engineering team hours of scraper building work each week before the public release. Firecrawl's core scraping engine is open source under the AGPL-3.0 license, and the company reports a roughly 63% average scrape success rate against an industry average of 59.3%.
Pricing
No standalone price; Prometheus runs on Firecrawl's credit plans. Free: $0/mo (1,000 credits, 2 concurrent requests). Hobby: $16/mo (5,000 credits). Standard: $83/mo (100,000 credits). Growth: $333/mo (500,000 credits). Scale: $599/mo (1,000,000 credits). Enterprise: custom. AI Extract is a separate token subscription from $89/mo.
Key Features
- Plain-English to working collector: Describe the data you want, like "top 5 Hacker News posts," and Prometheus writes a real Firecrawl SDK collector in TypeScript.
- Tested against the live site before handoff: Prometheus experiments against the live target site and runs the generated collector to confirm it works before returning the code.
- Managed scheduled runs with self-healing: Firecrawl can host the collector and run it on a schedule, automatically repairing it when the target site's layout changes.
- Reviewable, versionable SDK code: Output is real TypeScript source using the Firecrawl SDK, so engineers can read it, edit it, and commit it to git instead of a black-box config.
- Built on Firecrawl's scraping engine: Inherits Firecrawl's own scraping engine, which the company reports beats the industry average scrape success rate, across every credit-based plan.
Pros
- Generates actual reviewable TypeScript SDK code instead of an opaque no-code workflow, so engineering teams can audit and extend it.
- Tests the collector against the live site before handing it back, catching broken selectors before they reach production.
- Optional managed hosting with automatic self-healing means teams do not have to maintain scraping infrastructure themselves.
Cons
- No standalone pricing is published; usage draws entirely from Firecrawl's own credit plans, so heavy or frequent collector-building sessions can get expensive fast.
- Newly launched in 2026 (Firecrawl's 8th Product Hunt launch), so it lacks a long track record compared to mature scraping platforms.
- Tied specifically to Firecrawl's own SDK and credit system, so it adds little value for teams committed to a different scraping stack.
Data Handling
- Training-data policy
- Does not train models on customer scraped data; Enterprise plans include a zero data retention option
- Compliance
- SOC 2 Type II · GDPR/DPA · Zero Data Retention (Enterprise)
Frequently Asked Questions
What are Prometheus's pricing plans in 2026?
Firecrawl has not published a standalone price for Prometheus; it runs on Firecrawl's existing credit plans. The Free plan is $0/month, Hobby is $16/month (5,000 credits), Standard is $83/month (100,000 credits), Growth is $333/month (500,000 credits), and Scale is $599/month (1,000,000 credits), with custom Enterprise pricing above that. Every test run Prometheus performs while building a collector consumes credits from these plans. Firecrawl's separate AI Extract feature runs on its own token subscription starting at $89/month.
Does Prometheus have a free plan?
Yes, through Firecrawl's Free plan: $0 a month, 1,000 credits, 2 concurrent requests, and no card at signup. That allotment covers building and testing one small collector, such as a single-page scraper. Heavier or recurring use, especially a scheduled collector Firecrawl hosts for you, draws credits down faster and usually needs a paid tier.
Which tools compete with Prometheus in 2026?
Browse AI is the closest no-code option, letting non-developers train scraping robots by pointing and clicking instead of describing a request in English. Apify offers a marketplace of pre-built scrapers with scheduling and storage included, rather than one agent writing custom code on demand. n8n makes sense when scraping is one step inside a larger multi-app automation you are already building visually. What sets Prometheus apart is the output: reviewable, versionable TypeScript already tested against the live site.
Is Prometheus better than Browse AI?
Browse AI is a no-code, point-and-click platform for training scraping robots, while Prometheus takes a plain-English request and writes real, reviewable TypeScript code using the Firecrawl SDK. Browse AI runs its own separate credit system, while Prometheus draws on Firecrawl's plans starting free. Browse AI suits non-technical teams who want a visual robot builder and never need to see code, while Prometheus suits engineering and data teams who want to audit, version, and extend the generated collector themselves. Teams already using the Firecrawl SDK or MCP server get the added benefit of Prometheus's output slotting directly into that workflow.
How long does it take to get going with Prometheus?
Only as long as a Firecrawl signup takes, since the free plan needs no credit card. Describe the data you want in plain English, such as gathering pricing data from a specific webpage, and Prometheus experiments against the live site before handing back working TypeScript SDK code. You can run that code yourself, or let Firecrawl host and schedule it for you.
Top Alternatives
- Browse AI: Browse AI is the no-code, point-and-click robot builder, while Prometheus returns reviewable TypeScript generated from a plain-English request.
- n8n: n8n treats scraping as one node in a larger multi-app automation; Prometheus is the dedicated agent that builds and tests the scraper itself.
- Make: Make suits teams already building visual automations that need a scraping module, while Prometheus writes and validates the collector code.
