\begin{align*} y^{\prime }&=\frac {y+1}{1+t} \end{align*}

Solution by Maple

Time used: 0.003 (sec). Leaf size: 10

dsolve(diff(y(t),t)=(y(t)+1)/(t+1),y(t), singsol=all)
 
\[ y = c_{1} t +c_{1} -1 \]

Solution by Mathematica

Time used: 0.035 (sec). Leaf size: 18

DSolve[D[y[t],t]==(y[t]+1)/(t+1),y[t],t,IncludeSingularSolutions -> True]
 
\begin{align*} y(t)\to -1+c_1 (t+1) \\ y(t)\to -1 \\ \end{align*}
