Aedeon vs Devin · Updated October 13, 2026

Aedeon vs Devin: what each one changes, and how each one proves it.

Devin is the AI software engineer your developers assign work to. Aedeon is the system of record for how your software actually works, and the engine that evolves it.

Devin moves a backlog of tickets faster. When a single change reaches across applications, databases, pipelines and business rules, use Aedeon. It finds every dependency before anyone writes a line, and checks the new system against the old one on production traffic before it ships.

The New York Times evolved PLATO off Oracle onto Aurora with Aedeon, verified against production traffic before it shipped.

The short answer

Devin speeds up the team. Aedeon changes the system safely.

Devin

Devin, built by Cognition, is an autonomous software engineer. Your developers hand it work from Slack, Jira, Linear or the Devin app. It plans, writes code, tests in its own virtual machine and opens a pull request. In 2026 it grew into a family of tools: Devin Cloud, Devin Desktop, the Devin CLI and Devin Review.

Aedeon

Aedeon is the system of record for how your software actually works, and the engine that evolves it. Every application, database, pipeline and business rule goes into one living graph, Aedeon Graph. You state an outcome in a sentence. Aedeon Supervisor writes the plan, a person approves each gate, and Aedeon Evolve verifies the result on production traffic.

Which to choose

Choose Devin when the work is a stream of well-scoped tasks and your engineers own every merge. Aedeon is the better fit when one change crosses many systems and the person accountable for the cutover needs every dependency found first, with proof from real traffic before anything ships.

Same intent, two workflows

One change, delegated two ways.

Take the change Aedeon is best known for: getting a billing system off Oracle. Here is how the work moves through each product, step by step, based on each vendor’s own published description.

Intent“Get us off Oracle.”

With Devin

  1. An engineer writes the task.In Slack, Jira, Linear or the Devin app, naming the repositories in scope.
  2. Devin plans and writes the change.It explores the code, splits large work across parallel cloud sessions and edits the files.
  3. Devin tests its own work.Builds and tests run in Devin’s virtual machine, with a recording of the browser checks.
  4. Devin Review checks the pull request.Bugs and security findings are flagged before your engineers open the diff.
  5. Your engineers review and merge.Release and production checks run through your team’s existing process.

pull request ready

Outcome: tested pull requests, ready for your review.

With Aedeon

  1. One sentence states the outcome.Your architect types “Get us off Oracle.” That sentence is the whole brief.
  2. Aedeon Graph has already mapped the blast radius.Schema, queries and ORM, plus the nightly reconciliation job, two compliance checks and the BI feed that live outside the billing repository.Nightly reconciliation jobTwo compliance checksBI feed
  3. Aedeon Supervisor writes the plan and its price.Eleven steps with target files and an estimated cost. Your architects edit and approve it.
  4. Aedeon Evolve works gate by gate.Nothing executes until a person approves the gate in front of it, and every claim cites the code.
  5. Production traffic decides.The new system runs against the old one on real traffic. A divergence stops the gate.
  6. The change lands in your Git.Plan, graph version, approvals and verification runs travel with the commit.

verified · shipped

Outcome: a verified change, plus a map kept current for the next one.

Devin hands your team a tested pull request. Aedeon hands your team a change already checked against the old system on production traffic, and keeps the graph for the next change.

Credit where it is due

Where Devin is strong

Devin has earned its place on engineering teams. Three strengths stand out in Cognition’s own documentation and customer stories.

Devin strength · 01

Throughput on a backlog

Developers assign work from the tools they already use. Devin splits big tasks across parallel cloud agents and keeps working after the laptop closes. EBANX says Devin writes 92% of its merged pull requests.

Devin strength · 02

It tests what it builds

Every session runs in its own virtual machine with a shell, browser and editor. Devin tests in that browser and records the run, and Devin Review checks each pull request for bugs and vulnerabilities.

Devin strength · 03

Large refactors, proven in public

Nubank used Devin to split an ETL monolith of more than 6 million lines. Comarch is rebuilding a 10-million-line ERP with it.

Where Aedeon is different

What a system owner gets from Aedeon

Aedeon is built for the part of a change that sits outside the pull request. It finds every other system the change touches, and it proves they still work before the change ships.

  1. The map comes first, and it stays.

    Aedeon Graph is the Code Intelligence Graph, a living map of how your systems actually work. It resolves 15 kinds of entity and 16 kinds of relationship across code, databases, stored procedures, pipelines and configuration. Every fact carries the commit or schema version it came from. It maps 94 to 98 percent of business logic automatically and flags the rest as gaps for your team.

  2. Every claim cites the code.

    When an Aedeon agent says “these seven services read this table,” it has to point to the files, line ranges and schema objects behind it, at specific versions. A claim without a valid citation is rejected before it reaches a plan step.

  3. Proof comes from your own traffic.

    Before anything lands, the changed system runs against the old one on production traffic, with data, application and behavior checks in parallel. On The New York Times change, 2,412,880 requests were replayed and the gate opened at zero divergences.

  4. Each change is priced before it runs.

    Aedeon Supervisor attaches an estimated cost in credits to every plan. You approve it, then pay for the credits the steps actually used.

  5. Built for the person who signs off.

    Your VP of Applications or VP of Engineering states the outcome and approves the gates without writing code. Engineering teams still review and own everything that lands in Git.

Devin in 2026

What changed at Devin this year, and what it means for you

Devin ships fast. These are the 2026 releases buyers ask about most, taken from Cognition’s own announcements, each followed by our reading of what it means for a team changing core systems.

  1. Windsurf became Devin Desktop.

    Cognition rebranded the Windsurf editor as Devin Desktop. Devin now spans Devin Cloud, Devin Desktop, the Devin CLI and Devin Review.

    What it means for you

    More places for developers to work with Devin. The buyer is still the engineering team, and the unit of work is still a task.

  2. Security Swarm and multi-repository code scans.

    Devin added Security Swarm, which runs parallel agents to find vulnerabilities, and code scans that cover several repositories at once.

    What it means for you

    Useful for a security backlog. Every Aedeon change carries an impact analysis, and on Max the audit logs include SOX, PCI and HIPAA impact diffs.

  3. SWE-2.

    Cognition released SWE-2, its newest in-house coding model, in Devin Desktop and the Devin CLI.

    What it means for you

    A new model changes how Devin writes code. Aedeon’s planning layer is a separate proprietary model, Aedeon Supervisor, which decides what to change and in what order, then routes each step to the frontier models your organization approves.

  4. Devin for MongoDB Modernizations.

    Devin now runs inside MongoDB’s Application Modernization Platform, where it rewrites code and data access layers while the platform moves and validates records into MongoDB Atlas.

    What it means for you

    A strong option when your destination is MongoDB Atlas. Aedeon works toward any destination: The New York Times change went from Oracle 12c to Aurora PostgreSQL.

  5. Memory and Dreaming.

    Devin now keeps personal memories of each user’s preferences and corrections, refined by a daily background process.

    What it means for you

    Devin remembers how you like to work. Aedeon Graph remembers how your systems work, shared across your team, version-stamped, exportable and cited by every change.

Decide

Which one fits your situation

Choose Devin if

  • Your bottleneck is engineering capacity on a steady stream of tickets.
  • Developers will direct the agent and review every pull request.
  • Your destination is MongoDB Atlas and you want the MongoDB pairing.
  • You want an AI teammate inside Slack, Jira and the editor.

Choose Aedeon if

  • One change touches applications, databases, jobs and reports owned by different teams.
  • Business rules live in stored procedures and database policies nobody has mapped.
  • Someone has to sign off the cutover and wants proof from production traffic.
  • You want the map kept after the change, so the next change costs less.

Plenty of enterprises will run both. Devin works the backlog, and Aedeon changes the systems underneath it. Aedeon’s changes land in your Git like any other commit, so your existing review flow sees them.

Answers

Questions buyers ask about Aedeon and Devin

What is the difference between Aedeon and Devin?
Devin is an autonomous software engineer that your developers assign tasks to. It writes code, tests in its own virtual machine and opens pull requests. Aedeon keeps a living map of every application, database, pipeline and business rule you run. From one sentence it plans a change across all of them, gates each step for approval, and verifies the result on production traffic before it ships.
Is Aedeon an alternative to Devin?
For a change that crosses systems, yes. Aedeon plans, performs and verifies one change across applications, databases, pipelines and business rules. For day-to-day tickets inside a repository, the two products do different jobs, and many teams will keep both.
Can Devin handle legacy application migration?
Yes. Cognition publishes customer stories about this work, including Nubank’s split of a 6-million-line ETL monolith and Comarch’s rebuild of a 10-million-line ERP, and it partners with MongoDB on moves to Atlas. Aedeon’s difference is how the change is grounded and checked: a version-stamped graph of every connected system, and verification against the old system on production traffic.
How much does Devin cost compared with Aedeon?
As of October 13, 2026, Devin lists a Free plan, Pro at $20 a month and Max at $200 a month. Its Teams plan is $80 a month plus $40 per full developer seat, and Enterprise is priced on request. On the Aedeon side there is a free 30-day trial, then Pro at $20, Team at $80 and Max at $200 a month, with Virtual Private Aedeon from $50,000 a year. Every Aedeon change shows its estimated cost before you approve it.
How does Aedeon check that a change is safe?
Three ways. Every claim an agent makes must cite files, line ranges and schema objects at a version. A person approves every gate before it runs. Then the changed system runs against the old one on production traffic, and any divergence stops the gate until it is fixed and replayed.
Does Aedeon or Devin train on our code?
Aedeon never trains on customer code, on any plan, and that includes its own planning model, Aedeon Supervisor. On its enterprise page, Devin states that inputs and outputs are your intellectual property and that it enforces zero data retention with its model providers. Check Cognition’s terms for your plan.
What is Devin for MongoDB Modernizations?
Announced on September 29, 2026, it pairs Devin with MongoDB’s Application Modernization Platform. Devin rewrites code and data access layers while the platform moves and validates data into MongoDB Atlas. It suits teams whose target is Atlas. Aedeon works toward any destination, and its published customer change moved PLATO from Oracle 12c to Aurora PostgreSQL.
Which systems can Aedeon read?
Application code, databases and stored procedures, data pipelines and ETL, configuration, infrastructure definitions, and project context from tools like Jira, Confluence and Slack. COBOL and PL/I go into the same graph as Java, .NET, C++, Python, SAP ABAP and Oracle Forms.
Do we need consultants to run Aedeon?
No. Aedeon is a product and your team runs it. Services partners can help with hands-on delivery under their own contracts, and Aedeon never bills engagement labor.
How long does a first change take?
Connecting one system and watching the graph build takes about an hour. A first production change usually lands inside a quarter. The New York Times change ran twelve weeks end to end.
