OpenAI Codex

Pros

• Comes with existing ChatGPT plans, including a free tier and an $8 Go plan, so trying it costs little or nothing.
• Works across a CLI, IDE, desktop app, web, iOS and sandboxed cloud tasks, so developers can stay in their usual environment.
• Business plans include SAML SSO, MFA and admin controls, and business data is not used for training by default.
• Enterprise adds SCIM, EKM, RBAC, Compliance API audit logs and data residency for regulated organizations.
• Credits let teams keep working after hitting included limits instead of waiting for the window to reset.

Cons

• Usage limits are published only as wide ranges per five-hour window, which makes capacity hard to predict.
• In 2026 users repeatedly reported quotas draining far faster than expected, which forced OpenAI to reset limits for everyone.
• Forum users say the usage dashboard was buggy or delayed and support replies were generic.
• Fast and Ultrafast modes use included usage 2.5 to 8 times faster.
• Running Codex with an API key gives up the cloud features.

Salesforce Sales Cloud

Pros

• AgentExchange (formerly AppExchange) and built-in Slack integration give it the widest ecosystem of add-on apps and connectors among CRMs.
• Admins can tailor objects, Flow automation and dashboards in great depth, and reviewers on Capterra and SoftwareFinder repeatedly praise its customization and reporting.
• It scales from a free two-user suite to enterprise editions with sandboxes, high API allowances and security tooling such as Security Center and Data Detect.
• Agentforce AI is built in, with prospecting agents, pipeline forecasting insights and call coaching added in the Winter 27 release.
• Gartner has named it a Leader in CRM Sales Platforms for 20 years in a row, according to Salesforce.

Cons

• List prices rose again in September 2026. Core costs $195 and Advanced $395 per user per month, roughly 11 and 13 percent above the Enterprise and Unlimited editions they replaced.
• Many capabilities are paid extras, including API access on Pro, Agentforce, Sales Dialer and Revenue Intelligence, so the real budget is well above the entry price.
• Pro Suite and higher editions require annual contracts, and analysts note that downgrading mid-contract is difficult.
• Reviewers say small businesses often need an in-house admin or paid partners to run it, and that they use only a fraction of the features they pay for.
• Capterra gives it 4.0 out of 5 for ease of use, and G2 reviewers cite a steep learning curve for new users.
