Agenta vs PromptPerfect

Agenta is an open-source workspace for teams building and automating AI coworkers. Teams can interact with agents in Slack or Telegram, start from templates for engineering, customer support, sales, company knowledge, and operations, and run them on a schedule or in response to events. Its observability tools include traces, logs, errors, version history, evaluations, and token usage with estimated model costs. Agenta connects with services such as Slack, Notion, GitHub, HubSpot, Google Drive, Linear, Zendesk, and Discord, and supports more than 1,000 integrations. Listed model providers include OpenAI, Anthropic, Gemini, Mistral, and others. Cloud Hobby is free and allows two team members and 5,000 runs monthly; runs stop at that limit. Pro costs $29 a month and includes 10,000 runs monthly, with extra runs priced at $5 per additional 10,000. Model-provider charges are separate. Self-hosting is available, with users operating the application, storage, runner, upgrades, and backups in their own infrastructure. A mobile app supports agent conversations, approvals, and workspace management.

PromptPerfect is an open-source prompt optimizer from Beagle, available as a web app, Chrome extension, and API. In the web app, users submit a draft, choose an optimization mode, and receive rewritten text with an explanation of the changes. Modes include better, specific, cot, developer, research, beginner, product, and marketing. The Chrome extension is described as working on sites including ChatGPT and Gmail. Its API accepts a draft prompt and returns optimized text, an explanation, changes, the original text, provider, and model. Gemini, OpenAI, and Anthropic providers are supported. API keys can be supplied in the request body or as a Bearer token, with the Bearer token taking precedence. The homepage says keys stay in the browser and the project uses the MIT License. The Free plan costs nothing. Hosted Gemini anonymous callers share configured server-key quota.
