Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 35 stories with headroom
What would move Base44’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.
Agenticness — how well agents can access and operate the productPlug MCP servers into this product so it can use their tools
nonemoves agent-readyimpact 45
Evidence shows Base44 can expose its own app as an MCP *server* for external assistants (base44-docs-7), which is the reverse capability; there is no evidence Base44 itself can connect to and consume external MCP servers' tools as a client.
Openness — open source, data portability, and self-hosting storiesSelf-host the core product
nonemoves PA Scoreimpact 30
Evidence shows only that you can 'eject' an individual app's frontend/backend code into a new Base44-hosted project (still using Base44's platform with its own app ID), not that the Base44 platform/core service itself can be run on your own infrastructure.
Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models
nonemoves PA Scoreimpact 30
No evidence in the pack mentions any data-training opt-out, privacy controls over AI model training, or related policy language; the docs cover unrelated topics like CLI, SDK, domains, and login.
Agenticness — how well agents can access and operate the productGet AI-generated insights and suggestions from my data inside the product
nonemoves Built-in AIimpact 30
Missing: any documentation of data analysis/insight generation, dashboards, or suggestion features surfaced to end users.
Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background
nonemoves Built-in AIimpact 30
Missing: any mention of cron/scheduled jobs, background workers, autonomous triggers, or agents operating without live chat interaction.
Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent
nonemoves agent-readyimpact 30
Missing: any documentation of scoped API keys, permission levels, or least-privilege credential issuance for agents.
Agenticness — how well agents can access and operate the productSubscribe to events via webhooks
nonemoves agent-readyimpact 30
No evidence anywhere in the pack of webhook subscription/event functionality; documentation covers CLI, SDK, MCP server for external assistants, entities/CRUD, GitHub sync, but nothing about outbound webhooks or event subscriptions.
Agenticness — how well agents can access and operate the productExplore an interactive API reference with runnable examples
nonemoves API qualityimpact 30
Base44 provides static SDK/CLI docs with code snippets (e.g., docs-23, docs-28) but no evidence of an interactive API reference with runnable/executable examples; the probe explicitly found no OpenAPI/Swagger spec (404s across all candidate paths), indicating no such interactive reference exists.
