Most buyers should pick Twin.
Choose Adept if your work centers on multimodal digital agents, model research or composing web interactions with Adept Workflow Language. Choose Twin if you want a web-based assistant for prospecting, marketing and business tasks, with named app connections and monthly plans starting at $29. For developers, neither homepage documents a general-purpose API, SDKs or self-hosting. Confirm supported interfaces, usage limits and data export with the vendor before making either part of a production stack.

02Pricing at real usage
Neither vendor lists a free plan, and neither publishes free-trial terms. Adept offers enterprise access by custom quote, with seat and usage limits unpublished. Ask sales for expected spend, quotas and billing terms before sizing a deployment.
Twin lists monthly prices: Plus is $29, Pro is $149, Store starts at $399, and Enterprise is custom. Plus includes unlimited agents and scheduled runs, with up to five customer dashboards; Pro also caps dashboards at five. Store adds customer dashboards as you grow. The listed prices are plan fees, not a per-agent or per-run schedule, and Twin publishes no annual price or discount. For a small team, Twin has a calculable entry price; Adept's cost is quote-dependent. Confirm whether limits or charges change at higher volumes.
03API, SDKs and integration
Adept describes Adept Workflow Language (AWL) as an expressive custom language for composing multimodal web interactions on its models. Fuyu-Heavy is designed for digital agents; Adept also announces Fuyu-8B and Persimmon-8B releases. That points to model and workflow work, not a documented general-purpose API contract. Adept's homepage does not document API endpoints, SDK language support, CLI commands or rate limits. Ask what developer access is available before planning an integration.
Twin is a web assistant organized around business tasks and app connections. Its pricing page names Gmail, Slack, Notion, Sheets and calendars; its homepage advertises more than 5,000 apps and website connections. The product can draft outreach for review and report results in Slack. Twin's homepage does not document developer API or SDK details, so confirm supported interfaces, authentication and failure handling before treating it as a code-integrated service.
04Open source, self-hosting and lock-in
Adept has open-sourced Fuyu-8B and Persimmon-8B. Adept describes Persimmon-8B as permissively licensed, but its homepage does not name a license for Fuyu-8B. Verify the repository license and model-use terms before shipping either. These releases do not establish that Adept's hosted product or AWL is open source.
Twin's open-source status and license are not published on its homepage. Neither vendor documents self-hosting or data-export procedures there. Ask whether prompts, outputs, connected-app data, logs and agent configuration can be exported, and in what formats. If workflows depend on AWL or Twin-specific agent setup, plan for migration work unless the vendor documents portable definitions. Keep credentials in your own secret store where integrations support it, and test reauthorization and rollback paths.
Questions people ask
What's better than Adept?
For business prospecting, marketing and routine tasks, Twin may be a better fit: it lists those workflows, app connections and monthly plans. Adept is the closer match for multimodal agent research and composing web interactions with AWL. Neither homepage establishes a general-purpose developer API.
Does Adept offer a public API?
Adept describes AWL, a custom language for composing multimodal web interactions on its models. Its homepage does not document general-purpose API endpoints, SDKs, supported languages or rate limits. Ask Adept about developer access and production terms before designing around an API.
Is Twin cheaper than Adept?
Twin lists Plus at $29 per month, Pro at $149 and Store starting at $399. Adept's enterprise access is quote-based, with no published price. Twin has a public entry price, but the products serve different purposes and the prices do not establish equivalent usage or functionality.
Can I self-host Adept or Twin?
Neither homepage documents a self-hosting option. Adept announces open releases of Fuyu-8B and Persimmon-8B, but that does not establish that its product or workflow service can run on your infrastructure. Ask each vendor about deployment, data handling and export before committing.
