Devin vs Frederick

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors.

The short answer

Cheaper paid plan: Devin — $20/mo vs $25/mo for Frederick
Free plan: Both have one
Public API: Devin has one; not confirmed by us for Frederick
Best fit: Devin: Engineering teams delegating well-specified tickets such as migrations, test coverage and dependency upgrades · Frederick: First-time founders who want automated coding, research and scheduled tasks in one place
Platforms: Devin: Web, macOS, Slack app · Frederick: Web

What our research says

Devin

Devin is the agent to hand a whole ticket to and walk away from, and the $20 Pro tier makes that affordable to try for the first time. The quota is the catch: a long autonomous session can exhaust a plan quickly, and once it does you are paying API rates, so it suits teams that batch well-scoped tasks rather than developers who want a tireless pair programmer in the loop.

Pros

End-to-end autonomy: plans, codes, tests and opens the pull request from its own cloud machine
Fans one large task out across parallel agents and manages them itself
Native Slack, Linear, Jira and GitHub integration plus Desktop and CLI clients
Entry price dropped to $20 a month, far below the original enterprise-only positioning

Cons

Quotas are described only qualitatively ('light', 'generous'), so cost per task is hard to predict
Overage is billed at API pricing, which is where a runaway agent session gets expensive
Team tier adds a flat $80 a month on top of $40 per full user
Pages are heavily client-rendered; the terms live on cognition.com, not devin.ai

Frederick

Frederick has shifted from a business-plan generator toward a broader set of AI teammates that code, browse and run background tasks, which makes it more of a general startup-automation product than its original positioning suggests. The free tier is credit-limited enough that it works mainly as a trial before you land on Plus or Pro.

Pros

Three distinct agent types (coding, browser, background) instead of one general chatbot
Retains market research, SEO and landing page automation from its earlier product focus
Custom domains and priority support included on every paid tier
Annual billing knocks 24% off the monthly price

Cons

Free tier's 15 credits run out quickly for anything beyond a quick test
Product positioning has shifted since its original business-plan focus, which can confuse expectations set by older reviews
No API documented for connecting Frederick's agents to other tools
