This comparison exists because the words overlap and the layers do not. A gateway sits in front of the model calls your software makes in production. Fastpace sits around the AI tools your engineers use to write that software.
Portkey pricing and capabilities were read from the vendor’s own pages in October 2026. Products change. If something here is out of date, tell us and we will correct it.
We write this section first. A comparison that only lists wins is an advert, and it reads like one.
A free forever developer plan and a self-hostable open source build. You can start without asking anyone.
Deterministic guardrails in production, with custom hooks at Enterprise, for the calls your product makes.
Granular budget and rate limits with role-based access and SSO at Enterprise.
$49 a month for Production, with clear overage pricing. Most of this market will not say.
Your developers’ coding agents do not route through your product’s gateway. Fastpace records them at the machine.
A signed, hash-chained record built to be read by an auditor years later, rather than an operational log.
Commit trailers tie a change to the run that produced it. A gateway has no view of your repository.
One rule set compiled into each agent tool’s own enforcement format, not configuration inside one proxy.
The same ten questions appear on every Fastpace comparison, so the pages can be read against each other. A tilde means partly, and it carries a note.
| Capability | Portkey | Fastpace |
|---|---|---|
| Governs more than one AI coding tool† | ✕ | ✓ |
| Enforces policy where the developer works | ✕ | ✓ |
| Writes a signed receipt for each AI call† | ∼ | ✓ |
| Records the model, endpoint and training opt-out per call | ∼ | ✓ |
| Keeps a tamper-evident chain an auditor can verify | ✕ | ✓ |
| Ties a commit back to the run that produced it | ✕ | ✓ |
| Produces an AI bill of materials | ✕ | ✓ |
| Maps evidence to compliance frameworks | ✕ | ✓ |
| Finds AI use outside the governed tools | ✕ | ✓ |
| Runs locally, with no prompt text leaving the machine† | ∼ | ✓ |
Run Portkey in front of the product and Fastpace around the people building it. One controls what your software sends to a model. The other proves what the models wrote into your software.
A gateway and a development-governance layer are not alternatives. If someone has told you a gateway covers AI governance for engineering, it does not cover the laptops.
Developer is free forever with 10,000 recorded logs a month. Production is $49 a month plus $9 per additional 100,000 requests. Enterprise is custom. An open source version can be self-hosted.
Free tier: Developer plan, free forever, not for production. · Checked October 2026.
Fastpace: Community is free. Team is $29 per editor seat per month billed annually, or $36 monthly, with the first five seats free for twelve months. Platform is $99 per editor seat per month billed annually. Enterprise is custom. Viewer seats for CISO and GRC are free on Team.
No tool does. Fastpace produces evidence and maps it to the controls a framework names. The judgment stays with your auditor, and Fastpace holds no certification on your behalf.
The policy compiler reports what each target can and cannot enforce. Some settings are protected by the operating system and some a determined developer can route around. We would rather print that than imply a guarantee.
We publish no customer logos we cannot name and no statistics we cannot source. Ask us for a pilot rather than a reference wall.
The CLI ships under the Elastic 2.0 licence. It runs locally in your repository, and we call that source-available because that is what it is.
Developer is free forever with 10,000 logs a month and is not for production. Production is $49 a month plus $9 per additional 100,000 requests. Enterprise is custom, and an open source version can be self-hosted. Checked October 2026.
For some tools you can route model traffic that way, and it gives you cost and request logs. It still does not enforce what the agent may run locally, tie the call to a commit, or give you a signed chain.
If you ship an AI product and your developers use AI to build it, yes. They cover different traffic.
No. It records them from the tool side and governs the tool. It is not in the request path of your product.
