Syndai vs Devin
Syndai and Devin are the two most alike products on this site. Both take assigned work and return pull requests from a cloud agent. The main difference is what comes back and how you drive the work.
| Dimension | Syndai | DevinCognition |
|---|---|---|
| What it is | A coding service. You write a spec. It opens a pull request in your repo. Syndai can then issue a signed delivery receipt for the checks it ran. | Marketed as 'the AI software engineer'. It is an autonomous agent you assign engineering tasks to. |
| Where the work happens | In an isolated cloud sandbox, one per run. Your repo is cloned into it. Secrets stay on the sandbox side. Nothing runs on your machine. | In the cloud (Devin Cloud, paid tiers) or through the Devin Desktop app. |
| How you drive it | You write the prompt and review the result. The run plans, builds, and tests without you in the loop between those steps. | Delegated: assign a task and stay in the loop to manage and approve. Large tasks can fan out to a team of Devins in parallel. |
| What you receive | A pull request that lists the checks that ran, failures first. Syndai can then issue a signed receipt that lists each check, its result, and what code was checked. It merges only when your repository settings allow. | Pull requests, shipped the way your team ships them. |
| Pricing model | Plans are live and start free with no card; anyone can sign up. Runs can use Claude Max or ChatGPT. Provider API keys are not supported. | Plans: Free, Pro $20/mo, Max $200/mo, and custom Enterprise. Teams is $80/mo base plus $40 per developer seat. Paid tiers raise usage quotas. |
